A summarization of the data reported in this draft species/subject
report is intended for inclusion in the Draft Phase I final report for
the Adult Anadromous Fisheries subject area.
2.0 INTRODUCTION
This report presents the data collected on four species of adult salmon
in the Susitna River by the Alaska Department of Fish and Game (ADF&G)
during the 1981 Su Hydro Aquatic Studies.These studies are a part
of the Fish Ecology (Subtask 7.10)Phase I studies for the Susitna
Hydroelectric Project.
The primary objectives of the fish ecology studies for the Susitna
Hydroelectric Project are to:(1)describe the fisheries resources
of the Susitna River,(2)assess the impacts of development and operation
of the Susitna Hydroelectric Project on this fishery,and (3)propose
the mitigation measures to minimize adverse impacts (Alaska Power
Authority Susitna Hydroelectric Project,Environmental Studies
Procedures r~anual,Subtask 7.10,Fish Ecology Impact Assessment and
August 1981).The task"of meeting the first of these study objectives
is the responsibility of the ADF&G und2r a reimbursable services agreement
(RSA)with the Alaska Power Authority and the second and third are the
responsibility of Tet'restrial Environmental Specialists (TES).

The side scan sonar lSSS)counters used at the escapement monitoring
stations were deployed and monitored by trained personnel in accordance
with the 1980 Side Scan Sonar Counter Installation and Operational
Manual written by the Bendi~Corporation (J980).A brief narrative of
how a sonar works is provided in the following paragraph.
A sonar counter essentially converts electrical energy into acoustical
energy (sound waves}and counts underwater targets by measuring changes
in acoustical echoes.Each SSS counter is composed of a transducer,
aluminum substrate with reflector (target),an electronic-printer,a 12
volt battery,a solar charger and attendant cableware (Figures E.4.2 and
E.4.3).The transducer is vertically mounted on the shore end of the
substrate and emits repeating sound signals in a conical 2°and 4°
alternating beam just above the substrate.The transducer also receives
returning echoes from th~target which is mounted vertically on the
offshore end of the substrate.The entire substrate rests on the bottom,
perpendicular to the shore.As upstream migrant fish pass over the
substrate,they reflect transmitted sound waves back to the transducer
and are then recorded as counts on the electronic counter-printer.The
counter-printer tallys the counts and hourly provides a print-out of the
number of fish passing over each of 12 lineal substrate sectors.
During the 1981 season,each SSS counter was monitored a minimum of four
times daily for 30 minutes and fish related echoes displayed on an
oscilloscope were hand tallyed.The ratio of oscilloscope counts attributed
to fish and SSS counts were compared and used to adjust the counter for
accuracy.A fishwheel was operated near each counter to provide species

composition data for apportioning sonar counts.
The fishwheels used at each project location were of identical design
with two baskets and two paddles (Figure E.4.41.Floatation was provided
by styrofoam logs shielded by a plywood frame.The baskets had an
average length,width and depth of 2.4,1.7 and 0.6 meters (ml respectively
and were constructed of native spruce poles.The basket frames were
covered with three inch rubber coated fencing material which was replaced
during the season on most baskets by similar size creosote coated webbing.
The paddles were also made from spruce poles of the same length and
width as the baskets.The fishwheel axles were built from 20.3 centimeters
squared spruce logs capped at each end with a steel collar that held a
3.8 cm steel shaft set into self adjusting bearing blocks.The bearing
blocks were bolted to an adjustable wooded frame that permitted the axle
to be raised or lowered at 15.2 cm steps to a minimum and maximum height
of 30.5 and 122 cm,respectively,above the top of the floats.A 122 cm
long,76.2 cm wide and 122 cm deep live box was attached to the inshore
side of each fishwheel.
Each fishwheel was held in position in the river by a cable bridle
anchored to an onshore deadman and by an inshore mounted boom log lodged
between the bank and the inshore float.An inshore weir was used on
each wheel,except those at Sunshine Station to deflect inshore migrants
into the fishing area of the baskets.Weir panels were constructed of
alder and willow poles vertically spaced on one to two inch centers or
when available from three inch mesh,fencing material.

FigureE.4.4.FishwheeloperatingoffwestbankSusitnaRiveratCurryStation,AdultAnadromousInvestigation,SuHydroStudies,1981.
Each weir was built to conform to the river bottom at the location of
i nsta.ll ati on and extended from the shore perpendi cu1 ar to the downstream
end of the 1ivebox.Weirs were not used at Sunshine Station because of
debris problems.
All fishwhee1s were adjusted daily to insure that the baskets fished
within 15.2 cm or less of the bottom.Depending on site characteristics,
primarily river velocity,the wheels rotated at speeds ranging from 2.0
to 5.5 revolutions per minute (rpm).The preferred speed was 2.5 rpm
based on design.
All fishwhee1s were schedu1e.d to operate continuously 24 hours per day.
However,due to occasional flooding and excessive debris,maintenance
and repair work,and at Sunshine Station because of periodically high
catches which could not always be processed due to safety and personnel
constraints,continuous operation was not always possible.Sampling
checks were usually made four times daily at each fishwhee1.
Forty sockeye,25 chum,and 25 coho salmon were sampled daily for age,
length,and sex from fishwhee1 catches at sampling station.Age samples
were obtained by removing the "pre ferred lf scale located two rows above
the lateral line on a diagonal from the posterior insertion of the
dorsal fin to the anterior insertion of the anal fin.Sex was determined
from morphologic characteristics.Fork Length (FL)measurements were
taken from mid-eye to fork of the tail and recorded to the nearest
millimeter Cmm).Pink salmon,exclusively two year old fish,were
sampled only for length and sex at a rate of 40 per day per station.
Average processing time for collection of age,length and sex samples
E - 4 - 8
per fish usually ranged between 20 and 30 seconds.All fish were immediately
released following sampling.
All fishwheel intercepted sockeye,pink,chum,and coho salmon at Sunshine,
Ta"1 ke€!tna and Curry stati ons were tagged.An excepti on was that on
three non-consecutive days at Sunshine Station an insufficient number of
tags were on location to tag the entire catch.Two types of tags were
used (Table E.4.2.).At Sunshine and Talkeetna Stations color coded
Floy-4 spaghetti tags were deployed.One inch diameter Petersen disc
tags were used at Curry Station.The Petersen disc tags were inserted
throu9h the cartilage immediately ventral to the insertion of the dorsal
fin.Quarter inch diameter buffer discs were used to prevent the tagging
pins from wearing through the Petersen disc and causing tag loss.Floy
FT-4 spaghetti tags were inserted in same location as the Petersen disc
tags and each was secured against the back of the fish by a tightly
drawn overhand knot.Tagging time per individual fish ranged from 10 to
30 seconds.All fish were released immediately after tagging.

4.2 Survey Investigations
In mid July,a mobile crew was assigned to each of three subreaches of
the Susitna River mainstem between the estuary and Devil Canyon as
outlined below:
Susitna Station Survey Crew
Sunshine Station Survey Crew
Estua ry to (RM a to RM 61)
Kashwitna River
Kashwitna River (RM 61 to RM 108)

Canyon
(RM 108 to RM 151)
The crews used a combination of drift gill nets,e1ectroshockers,echo
recorders and egg deposition pumps to sample the mainstem Susitna River
for presence or absence of mainstem spawning activity.Drift gill nets
were deployed over a wide range of sites.Site selection was based on a
brief visual assessment of the following criteria which generally
suggested suitability of a particular site as a spawning area and the
feasibility of operating a drift net:
1.Substrate composition
2.Relative water velocity
3.Water turbidity
4.Water depth
E - 4 - 0
5.Presence of debris
6.Presence of spawned
out fish or fish surfacino.
Several times during the season high water conditions obscured many of
the visual clues used to identify potential spawning sites.When this
occurred,aerial photographs taken earlier during low water flows were
examined and from the photos likely spawninq areas were identified and
sampled.
Drift gill nets used in sampling the mainstem were 15.2 m long,1.5 m
deep,13.3 cm stretch mesh nylon web,fished from 6.1 m,flat bottom
riverboats each equipped with a 75 horsepower jet outboard.A net was
typically deployed by casting one end into the river from the bow of the
boat as it moved slowly in reverse.The other end of the net was tied
to the bow and the boat was then maneuvered in a manner that the net
extended semi-perpendicular to the river current.Surface and subsurface
debris along with fluctuating depths qenerally governed the distance
fished.These same nets were used in areas that were either too shallow
or too narrow to sample effectively by the drifting technique.In some
cases,the net was used as a set net by anchoring one end to the boat
bow and the other end to a portable anchor or natural deadman.In other
instances,the net was deployed as a seine by manual means.
Salmon caught by drift netting,seining or by set netting were not
assumed to be spawning at the catch location unless all of the criteria
listed below were met:
1.Fish exhibits spawning maturation color and morphology.
2.Fish expe1ls eggs or milt when slight pressure is exerted on the
abdomen.
E -4 -
3.Fish is in vigorous condition,with an estimated 25 percent or more
of the eggs or milt remaining in the body cavity.
4.Additional fish are provided from the site that meet criteria 1
through 3 above.
Survey crews were equipped with a Lowrance Model LRG~15l0B echo recorder
to survey the Susitna River mainstem for salmon spawning activity.The
plan was to locate fish by directing the transducer beam horizontally
across the river bed.A horizontal mode was chosen because of the
limitation of vertical scans due to restricted water depths in the
mainstem.In conducting a horizontal side scan the recording unit was
nearly always tuned to record at the 9.1 or the 18.2 m range to take
advantage of refined dimension in resolution and detail on the graph
printout.The sensitivity setting on the recorder was set at the 3/4
point or higher for additional detail.The transducer was attached to
an adjustable aluminum gunnel bracket that allowed it to be lowered into
the water column at various depths.Echo recordings were taken with the
transducer in the horizontal mode at depth ranges from two feet from the
surface to one foot from the bottom.Sites surveyed were ~enerally
semi-placid areas of the river due to the limited ability of the transducer
bracket to withstand water force without bending or breaking.
The Sunshine and Gold Creek survey crews conducted salmon enumeration
counts on all spring fed sloughs and tributary streams between the
Chulitna River and Devil Canyon on a scheduled weekly basis.In addition
the Sunshine survey crew made tag recovery counts at pre-selected times
on several known spawning tributaries between Sunshine Station and the
E -4 - 1 2
Chulitna River confluence (Table E.4.3.}.

The spawning ground surveys were performed on foot by two crew members.
One counted live fish and the other counted carcasses.Tag recovery
counts were made at the same time by the crew member enumerating live
fish.Tag type and color were recorded by species on each live fish
bearing a tag.The second crew member removed tags from carcasses and
recorded the tag type,number,color and species.
From late July to mid September,the Gold Creek crew fished four hours
every five days,one -15.2 m long,1.5 m deep,13.3 cm stretched mesh
E - 4 - 3
nylon gill net in eddies in the mainstem between Deyil Canyon and at RM
149.4,1!2 mile above Portage Creek.The gill net was staked at one end
to the shore and held off shore at the other end in a slight downstream
arc by a 35 pound Navy anchor.The species and spawning condition of
the fish caught in the net was recorded.
The survey crews electroshocked areas of the mainstem Sus;tna River with
a Model VVP~3C Coffelt electroshocker,using a 3500 watt Homelite generator
as a power source (Figure E.4.5).Input to the electroshocking unit was
230 volts alternating current (A.C.)and output voltage was one of three
types,A.C.,direct current (D.C.),or pulsating D.C.One to three and
one half amps of D.C.or pulsating D.C.was found to be effective
capturing adult salmon.The output power was split with one lead going
to a foot switch and the other to the electrodes;the anode (+)electrode
being the dip net and the cathode (-)electrode the boat.Depression of
a foot switch allowed the flow of current through the water.The activation
period ranged from five to ten seconds followed by a 20 to 40 second
pause to avoid a possible herding effect on fish.Safety was accomplished
through the use of rubber boots and gloves;in addition,a kill switch
was attached to the generator and kept in a ready position by the boat
operator at all times.
Egg deposition sampling was conducted with a Homelite two cycle,single
stage,backpack mounted water pump and two circular,standing screen
baskets with cod and nets.Each basket sampled a 1,800 cm 2 area.
The height of the basket was 45.7 cm.Samplin9 with this gear was

limited to areas of not more than 45.7 cm deep and where electroshocking
or gill netting produced fish which met the previously defined criteria
for spawning or where visual surveys earlier in the season revealed
suspect redds or spawning activity.
4.3 Radio Telemetry Investigations
Radio tracking operations targeted on chum and coho salmon,a sample
size of 11 chum and 10 coho salmon was chosen in this study.The radio
telemetry transmitters,receivers,and antennas were obtained from the
Smith-Root Corporation.Transmitters were individually identifiable and
operated on a carrier frequency ranging from 40.650 to 40.740 mHz.
Transmitter life expectancy was 75 to 90 days.
Each transmitter was encased in a rubber coated,waterproof plastic case
and anchored to an insulated,water tight antenna wire.The transmitters
were cylindrical in shape,weighed 23.6 grams each and measured 7.6 em
long,by 1.6 cm in diameter.They were fitted with a 13.0 cm long
antenna.A small bar magnet was taped to each transmitter to break the
electrical circuit and conserve battery life until used.
Prior to field operations,the radio transmitters were immersed in water
for 48 hours and tested for signal strength and frequency on both manual
and scanning receivers.Malfunctioning transmitters were returned to
the manufacturer for repair.To enable anglers to return the transmitter
and catch data to project personnel,adhesive waterproof labels were
then affixed to those transmitters which tested satisfactorily.
E - 4 - 6
Preliminary literature research revealed no information about internal
radio transmitter implants on chum salmon.During late July three adult
chum salmon were experimentally radio tagged with dummy transmitters to
insure that proposed techniques would not injure the fish.Sample
specimens were taken from Sunshine Station fishwhee1s.Each fish was
transferred by net from the fishwhee1 holding box to a wooden,two
compartment tank containing approximately 60 liters of fresh Susitna
River water in each compartment.Within 2 to 5 minutes the fish would
usually relax and be measured (FL)before being examined briefly for
external wounds and spawning condition.Vigor was appraised prior to
and during this inspection and any fish displaying little or no movement
or loss of equilibrium was deemed "stressed".Fish with fresh wounds or
those fitting the definition of "stressed"were classified as unsuitable
for tagging.Stressed fish were gently removed from the tank and held
in shallow,slow moving water by hand until they revived and forcefully
sv.Jam away.
Three fish were found to be suitable for experimental tagging and preparations
were made to implant the radio transmitter.Tricaine methanesu1fonate
(MS~222),an anesthetic,was sprinkled sparingly in the water of one
compartment in an amount that caused a slight decrease in opercular
movement followed by loss of equilibrium within 2-5 minutes.Slightly
more anesthetic was added if the fish remained active after the first
applications.
Before implantation,a #2,nickel finish,beak hook was tied to the free
end of the antenna wire.The antenna,with attached hook,was placed
E -4 -7
hook first into a 1.95 cm diameter,50.2 cm long plexiglass tube which
served as an insertion instrument.A wider 1 2.5 cm diameter,32.4 cm
long plexiglass tube was slid over the small tube until the transmitter
was cradled in the larger tube.Glycerine,a water soluble lubricant,
was liberally poured on the transmitter to ease insertion in the fish.
As one person held the fish ventral side up with the head elevated at
about a 45 0 angle,the other person inserted both tubes and the transmitter
to the fish's esophagus.The smaller rod was slowly pushed inward until
the transmitter disappeared from view into the stomach.The fish was
immediately immersed for 20 to 30 seconds and lifted again at the same
angle.The antenna hook was positioned slightly off center in the roof
of the mouth to prevent rupturing a major artery and pressure applied
until the barb protruded (Figure E.4.6).The transmitter was verified
to be in its original positton.The fish was transferred to the adjacent
compartment of the tank containing fresh water and revived.
The first experimentally implanted transmitter was positioned in the
poste~rior of the stomach [Figure E.4.7(A)J.Immediately after tagging,
the fish was pithed and necropsied.The stomach was found to be very
thin walled and had ruptured.The tear was 5.3 cm long and extended
from the posterior end of the transmitter toward the fish's mouth.The
second and third chum salmon experimental implants were made in progressively
anterior positions,posterior of the esophagial sphincter muscle.
Despite the anterior transmitter location the thin walled stomachs
ruptured IFigure E.4.7lB~C)J.The antenna also extended too far forward
in the fish's mouth;allowing it to sag and become entangled in the
lower jaw and gills.

From these results the decision was made to implant the transmitter in
the anterior portion of the stomach cavity in chum salmon [Figure
E.4.7(0)J.This location was determined to be when the anterior (antenna)
end of the transmitter just disappeared from sight behind the esophagial
sphincter.When so positioned,the rubber coated reinforcement at the
antenna/transmitter connection point is visible in the rear of the
fish's mouth.
The problem of antenna placement was remedied by lacing the antenna
through the fish's kype.To accomplish this the hook method was rejected
and an extension was added to the antenna.A six inch piece of heat-to-
shrink material,a wire insulating material made of plastic,was fastened
to the anterior two cm of the antenna.Following transmitter implantation
a hollow Floy tagging needle was used to pierce the kype from inside the
mouth.Care was taken to avoid puncturing the major artery that lies at
the center of the roof of the mouth.The heat-to-shrink material was
slid into the hollow needle and the needle pulled through the kype.
lacing the elongated antenna through the tissue.This allowed maximum
extension of the antenna without damage to gills and simultaneously
suspended the antenna so that signal transmission was enhanced.The
antenna extension was secured to the dorsal surface of the kype by
crimping one-half of a precut size 10/12 electrical butt splice on the
heat-to-shrink material.A plastic buffer pad was placed between the
flesh and the butt splice to prevent tissue damage.Any excess heat-to-
shrink material was then removed above the butt splice.
~-d -?1
During live fqdio transmitter implants the procedures outlined above for
fish capture qnd selection were used.Prior to insertion however,the
tag was checked a final time while submerged in a contqiner of water and
tested for signal strength and frequency of transmission.The heat~to
shrink material was installed on the antenna wire qnd the fish anesthetized
as described previously.Sex of the fish was determined by external
examination of morphological characteristics.The fish was then suspended
in a moistened canvas sling and weighed to the nearest 0.1 kg and returned
to the anesthetic tank.As the fish was held firmly against one side of
the tank a numbered Petersen disc with buffer pad was mounted on a pre-
sharpened needle and inserted about 2.5 cm beneath the second dorsal fin
ray.A blank Petersen disc was then slipped on the protruding needle,
and the disc snugged against the flesh by twisting the needle firmly
against the blank disc.The measuring,weighing and Petersen disc
tagging process usually took 60 to 90 seconds.
The radio transmitter was next inserted and the antenna anchored through
the kype.Four to six fresh river water changes were made while the
fish recovered.When the fish displayed increased muscu1ar and gill
activity it was carefully removed from the tank and held by hand in the
river until it forcefully swam away.Tag implanting and antenna anchoring
usually took two to three minutes.Total elapsed time for the entire
tagging process between introduction of MS~222 and first addition of
fresh river water varied from eight to 12 minutes,depending on how long
it took the fish to become sedated.Recovery times from the anesthetic
ranged from seven to 30 minutes depending on how much MS-222 was required
to sedate the fish.
E -4 -2 2
During the tagging process the fishwheel was deactivated for 20 minutes
to prevent recapture upon release.Movement of the fish was noted with
a loop or paddle antennae for ten to 20 minutes after release (Figure
E.4 .8).
Fish tracking was conducted by boat along the mainstem Susitna River
from (RM)99.0 to as far upstream as RM 142.0.Tracking was conducted
from a 6.6 m Wooldridge riverboat powered by a 460 cm 3 four cylinder
inboard engine with a two-stage Hamilton jet.Tracking occurred at one
to four day intervals depending on stream flow conditions and fish
distribution.
Fish tracking was conducted with a manual and a scanning receiver powered
by battery packs:The receivers and battery packs were encased in a
wooden,waterproof box.A large loop antenna and an outdoor speaker
were connected to the scanning receiver to detect and signal the occurrence
of a radio tagged fish while monitoring from the boat.A smaller paddle
antenna was connected to the manual receiver to pinpoint a tagged fish's
location to within six meters.While the scanning receiver automatically
searched all transmitter frequencies in use,the individual operating
the manual tracker scanned for transmitter frequencies when a tagqed
fish was detected.A triangulation procedure was implemented by rotating
the loop antenna slowly from various river locations.The position of
the fish was determined and its location plotted on black and white
aerial photographs (scale 1 :4,000}of the river.Its position was then
logged to the nearest 0.1 river mile.

Mon itori ng of tagged fi sh was conducted by air at one to four day i nterva 1s
from a Cessna 185 aircraft.A loop antenna was fastened to each wing
strut with hose clamps.The antennas were fixed parallel to the fuselage
with the handle facing forward.The broad face of the loop faced the
fuselage and the narrow surface of the loop was perpendicular to the
ground.One antenna was connected to a manual receiver and the other to
a scanning receiver inside the airplane.Each antenna cord was reinforced
with duct tape where it passed through the doorway.A speaker was
connected to the scanning receiver and headphones to the manual receiver.
The manual receiver was monitored by one person while the other monitored
the scanning receiver and plotted the position of the aircraft.Locations
of tagged fish were identified by signal strength to +0.1 mile and
marked on vinyl encased,black and white aerial photographs (scale
1 :40,000).
Radio transmitter implantation methodology for coho salmon was initially
identical to that described for chum salmon,however transmitter and
antenna modifications were required to prevent transmitter regurgitation
by adult coho salmon.The first two tagged coho salmon carried extremely
anterior implanted transmitters with the heat-to-shrink material antenna
modification.However,the third tagged coho salmon regurgitated the
transmitter while recovering from tag implantation.
To prevent future transmitter regurgitation by coho salmon,a wire
modification was adopted.A 30 cm long piece of 16 gauge baling wire
was wrapped twice around the anterior tip of the transmitter and extended
forward,parallel to the antenna.Several wraps of waterproof plastic

extended and taped to the wire to enhance signal transmission and prevent
it from causing possible abrasion to the fish.
Implantation techniques were identical to those for chum salmon although
prior to pushing the sharpened wire through the kype,an outward facing
loop was made,so that it rested against the inside of the kype.A
buffer was then snugged against the dorsal side of the kype and one half
of an electrical connection was crimped over the wire and against the
buffer.The wire loop and buffer-crimp combination prevented the transmitter
from moving forward and being regurgitated by the fish.
4.4 Data Analysis
Population estimates presented in the report were calculated using the
following formulas (Ricker,1975):
AN =mc/r
Where:m =Number of fish marked (adjusted for tag loss).
c =Total of fish examined for marks during sampling census
r =Total number of marked fish observed during sampling census

The 95%confidence limits around N were determined by using the formula

Tag loss was calculated using data derived from repeated spawning ground
surveys of placid sloughs where survey condHions permitted unrestricted
(visual)observation of tag loss through inspection of spawning areas
for shed tags and accurate enumeration of fish with tags in place.In
calculating tag loss,the number of tagged fish examined (t)were
summed with the number of loose tags (1)respective to tag type.The
resulting summation (1 +t)was then divided into the number of fish
with tags (t)in place to provide a percentage on tag retention (R).The
above is mathematically stated in the formula:t
+t
=R x 100%.
The percentage was then mu1tip1fed by the number of fish by species tagged
at the particular tagging location being examined,for an appropropriation
adjustment to the number of fish released.
Age determination was made by scale examination using a portable microfiche
readE!r and the age class described using Gilbert-Rich notation.By the
notation,age 42 fish are those fish in their fourth year of life that
migrated from freshwater to the marine enviornment in their second year
of life having spent one winter rearing in fresh water.

5.0 Results and Discussion
5.1 Mainstem Investigations
Table E.5.1.summarizes the salmon escapement estimates by species at
each of the mainstem Susitna River and Yentna River stations (Figure
E.5.l.)as determined from SSS counters and Petersen tag and recapture
operations.Fishwhee1 catches are summarized in Table E.5.2.Daily
sonar counts and fishwheel catches by sampling station are provided in
Tables EB-l through EB-8 and ED-1 throuqh EC-10,respectively.The
following subsections outline by species the specific results of escapement
sampling at the above defined stations.
Sockeye Salmon
At Susitna Station 340,232 sockeye were counted (Table E.5.1 .).Fifty-
one percent of those counted migrated across the east bank SSS counter
and 49 percent over the west bank counter.The migration principally
extended from 29 June to 24 August with the mid-point occuring on 17
July (Figure E.5.2).Seventy-five percent of the sockeye escapement
passed in a 13 day period from 11 July to 23 July.Fishwhee1s operating
at Susitna Station intercepted a total of 4,087 sockeye salmon.Fishwheel
catch per hour plotted against time (Figure ED-1)indicates the peak of
migration occurred between 10 July and 19 July with the majority of the
sockeye salmon migrating along the west bank.
A total of 139,401 sockeye salmon were logged by the SSS counters at

Yentna Station ~ab1e E.5.11.Ninety-two percent migrated over the
south bank and eight percent over the north bank counters.The beginning,
mid-point and end of migration occurred on 1 July,16 July and 3 August
respectively (Figure E.5.2l.Seventy-five percent of the fish passed in
a 12 day period between 12 July and 23 July.A total of 7,000 iockeye
were caught in fishwhee1s at Yentna Station.Fishwhee1 catches indicate
that the peak of migration occurred between 13 July and 15 July with the
majority of fishwhee1 interceptions (70.0%)on the south bank (Fiaure
ED-l}.
Sunshine Station passed 89,906 sockeye salmon over the SSS counters.
Sixty eight and nine-tenths percent were counted on the east bank sonar
and 31.1 percent on the west bank counter.The migration began principally
on 16 July,reached a mid-point on 23 July and was over on 20 August
(Figure E.5.2).Seventy-five percent of the sockeye migrated over the
counters in an 11 day period between 19 July and 28 July.A total of
9,528 sockeye salmon were intercepted by fishwhee1s at Sunshine Station.
Based on fishwheel catch records (TcibTe EO-2)the peak migration occurred
between 18 July and 23 July.The highest catches (83.2%)were made on
the east side of the river.
At Talkeetna Station 3,464 sockeye salmon were counted.The majority of
the fish (54 percent)were enumerated on the west bank SSS counter.The
migration principally began on 23 July and was complete by 8 August.
The mid-point occured on 31 July (Figure E.5.2).Seventy-five percent
of the fish were counted between 23 July and 6 August.Talkeetna Station
fishwheels intercepted 391 sockeye salmon.from a plot of the mean
E - 5 - 6
hourly fishwheel catch (Figure ED~21 it ~ppears that the peak of migr~tion
occun'ed between 27 July and 1 August with sockeye showing no apparent
bank preference.
Curry Station fishwheels interce~ted a total of 470 sockeye salmon with
the majority (87.2%)caught on the east bank.A plot of fishwheel catch
per hour indicates that migration began,reached a mid-point and ended
on 18 July,5 August and 29 September respectively (Figure ED-3).
Accuracy of population numbers generated by SSS is dependent upon site
location and species enumerated.Recognizably,sonar counters do not
enumerate every fish that migrates upstream.They accurately count
those which pass over the counting plane or substrate of the counter but
not those which migrate outside or offshore of the range of the sonar.
Water depth,velocity,channel configuration and location or absence of
obstructions are variables which influence where salmon migrate in the
river'at a particular time and location.It has been shown that sockeye
and pink salmon usually migrate near shore within 60 feet or less of the
bank (Tarbox,et.al.,1980).This appears to be generally less true of
other salmon species.However,at Sunshine Station chum salmon were
found to migrate closer inshore than sockeye salmon at either Susitna,
Yentna,or Sunshine stations (Figures E.5.3 and E.5.4).
Sonar sector count data indicates that salmon,of all species,tend to
display greater bank preference the further they progress up the Susitna
River (Figures EE-l to EE-8).To illustrate this,42.6 percent of the
counts on the east bank and 18.7 percent on the west bank at Susitna

Station were registered in offshore sectors 6 to 12.At Talkeetna
Station,4.9 percent and 2.2 percent were recorded in the same sectors
on the east and west bank respectively,an indication that SSS counters
become more effective counting all salmon species in the upper reaches
of the Susitna River.This is probably due to water velocities,channel
configuration and river gradient.
Socke'ye salmon population estimates derived from fishwheel tagging
operations at Sunshine,Talkeetna and Curry Stations indicate that
approximately 130,450,4,800 and 2,800 sockeye salmon were present at
each site respectively.The 95%confidence limits on these estimates
a10n~1 with the components used to calculate them are presented in Table
E.5.3.
These population estimates,as with others which will be presented on
the in this report,should not be considered to be the actual number of
fish"in this case sockeye salmon,that spawned upstream of the tagging
location.The sockeye estimates represent only the number that were
present at the particular tagging station.Other Susitna River investigations
have revealed that all adult salmon species mill to some degree in the
mainstem and that it is not uncommon to find adult salmon in the Illainstem
well upstream of their spawning destination (Barrett,1974 and Friese,
1975).
A further factor in considering the population estimates is tag loss and
tag induced mortalities.Both are capable of introducing positive bias
to the estimates (Everhart,et.a1.,1975}.Tag induced mortal ities
were not considered significant due to minimal amount of time (10-20

seconds)required to tag a fish,and the general vigorous condition of
the fish caught in the fishwheels.Tag loss was taken into consideration
by adjusting the total number of fish tagged by species according to
percent occurrence of loose tags found during foot surveys of clearwater
spawning sloughs.This provided an independent tag loss factor for
Sunshine Station and Talkeetna Station which was 7.5 percent and 3.4
percent respectively (Table E.5.4).The difference in tag loss factor
between the two stations can be attributed to the difference in tag~inq
quality.At Sunshine Station the total number of fish tagged was 24,159
compared to 2,176 at Talkeetna Station.The maximum number of fish
tagged in a single day at Sunshine Station was approximately 1,700 fish
versus 250 fish at Talkeetna Station.The tag loss factor of Curry
Station tagged fish was presumed to be insignificant (less than one
percent)based on survey crews not finding any shed Petersen disc ta~s
during spawning ground surveys and the general difficulty encountered in
removing these tags from carcasses.

There is some discrepancy between populations estimates from sonar
counts of fish,versus estimates from the tag and recapture project
(Tabl,:E.5.1l.Both estimates have deficiencies that must be recognized.
It should not be assumed that all fish pass over the SSS substrate.As
previously discussed,the sector distribution of salmon will vary with
site and species,with an undetermined number of salmon passing beyond
the SSS counting range.A major source of error present in SSS counts
is related to the methods of apportionment and the bias inherent in
those methods.Although all fishwheels used to apportion the SSS counts
were in close proximity to the counters it must be recognized that
fishwheels can be species selective.The apportioned sonar counts would
then reflect the selected catchability of the fishwheel.In addition,
SSS counters are adjusted for fish velocity and sensitivity,thereby
introducing an unknown variance component into the counts.Methods of
calculating confidence intervals around the population estimates are not
available for SSS counts because,at this time,it is not feasible to
duplicate a counting sample at one site at the same time,which does not
allow for a sampling estimate for the variance.It should be realized
that SSS counts are not absolute population numbers and at this time
should be considered an index of species abundance at a specific location.
Tag and recapture methods of estimating the population and the Petersen
estimate in particular make six assumptions which are listed in Begon
(1979).It is realized that failure to meet these assumptions will bias
the population estimate and consequently the confidence intervals.The
following assumptions were made in estimating population size:fishwheel
capture of salmon was random with respect to the population;there was
no mortality as a result of the tagging process;there was no differential
E -5 -1 3
morta"lity between tagged and untagged salmon;tagged salmon mixed randomly
within the population;and recovery of tagged salmon was not influenced
by the tag.The net result of tag 10ss 1 if not accounted for,will
result in an overestimation of the population and conversely if tagged
salmon are more readily visible than untagged salmon the resulting bias
will cause the population estimate to be low.In summary,it should be
recognized that both methods of enumerating salmon have potential drawbacks
but at this point they represent the state of the art in estimating
popu1,~tion sizes in glacial river systems.The discrepancy,where they
exist,between Petersen population estimates and SSS counts reflect the
limitations inherent in both techniques.
From the sonar data the miqrational timing of sockeye salmon between the
mainstem sampling stations indicates that those passing Susitna Station
bound to the Yentna River made the six mile trip in one day or less,and
of the fish migrating past Susitna Station to Sunshine Station and
destined to Ta'lkeetna Station had an average travel time of 8 days and
13 days respectively (Figure E.5.5).This is an average travel rate of
6.8 miles/day between Susitna Station and Sunshine Station and 4.6
miles/day between Sunshine Station and Talkeetna Station.These migrational
rates are considered valid if there is no fundamental variation in
timing between Susitna River sockeye salmon stocks.
An insufficient number of tagged sockeye salmon recaptures were made at
Talkeetna Station to determine the average travel time rate between
Sunshine Station and Talkeetna Station.The data indicates that the
minimum travel time between these stations was three days or a travel

speed of 7.7 miles/day (Figure E.5.6}.Tag recaptures of sockeye salmon
at Curry Station indicates a minimum travel time of five days from
Sunshine Station to Curry Station and one day from Talkeetna Station to
Curry Station (Figure E.5.71.The average migration time between Talkeetna
Station and Curry Station based on the tag recapture data was approximately
five days or a travel speed of approximately 3.5 miles/day.
Our investigations reveal that sockeye salmon generally reduced their
travel speed the farther they migrate upstream.A possible explanation
for this observation is that sockeye salmon dtsplay greater milling
behavior as they approach their natal stream therein reducing their net
travel speed.This behavior was indicated by a significant number of
sockeye salmon recaptures at Talkeetna Station that were intercepted
more than 26 days earlier at Sunshine Station located 23 miles downstream
from Talkeetna Station (Figure E.5.6).
The sonar counts and fishwheel catches at Susitna Station,Yentna Station,
and Sunshine Station indicate a strong preference by sockeye salmon to
favor one bank of the river depending on the location.Sockeye salmon
were more abundant on the west side of the Susitna River at Susitna
Station and were more numerous on the east bank at Sunshine Station.
Yentna Station recorded higher sonar counts and fishwheel catches along
the south bank along off the north bank.At Talkeetna Station,sockeye
salmon utilized both sides of the river without any notable preference.
The fishwheel catches at Curry Station indicate that sockeye are significantly
more abundant on the east side of the river than on the west side (Figure
ED~3).

The migrational preference displayed by sockeye salmon for a particular
side of the river appears to be closely tied to site characteristics
when proximity or distance to a spawning area is not a factor.Agents
influencing bank preference in a specific reach of the river may be
velocity,water depth and channel configuration and presence or absence
of navigational obstructions.
Evaluation of hourly passage rates indicate distinct behavior patterns
of sockeye salmon migrants at Susitna Station.Yentna Station and Sunshine
Station (Figure E.5.8).Higher than average passage rates occurred
between 1900 hours and 0100 hours at Susitna Station and lower than
average passage between 0700 hours and 1100 hours.At Yentna Station
sockeye salmon exhibited greater upstream movement between 2300 hours
and 0500 hours and displayed lower than average upstream movement between
1100 hours and 1500 hours.Sockeye salmon at Sunshine Station moved
less between 0700 hours and 1100 hours than at any other time and displayed
a higher than average preference for movement between the hours of 1900
and 0100.
Sockeye salmon age composition samples,collected in fishwheels,revealed
that the majority of the sockeye salmon at each of the sampling stations
were age 52 (Table E.5.5).The next abundant were age 42 sockeye followed
by age 62 sockeye.Five year old sockeye,1976 brood year,comprised
approximately 86 percent of the return at Susitna and Yentna stations,
73 pl:rcent at Sunshine and Talkeetna stations and 70 percent of the
sockeye at Curry Station.four year old sockeye,1977 brood year made
up 8.5 percent of the escapement return both at Susitna Station and

571mm,and 584mm at Susitna,Yentna,Sunshine,Talkeetna and Curry
stations respectively.The average length of five year old female
sockeye salmon in the same order respective by station as defined above
was 568mm,577mm,553mm,551mm and 560mm.The combined sockeye salmon

females in all age classes (Table E.5.6)but were more numerous than
female sockeye at only Talkeetna Station (1.2 to 1.0).At Sunshine
Station sex ratios indicate that male and female sockeye were equally
abundant (1.0 to 1.0).Males were less abundant than females at Susitna

Pink Salmon
Side Scan Sonar counters at Susitna Station enumerated 113,349 pink
salmon;88 percent on the east side and 12 percent on the west side of
the Susitna River.The pink salmon migration essentially began,reached
a mid-point and terminated on 10 July,25 July and 21 August respectively
(Figure E.5.9).Seventy-five percent of the pink salmon migration
passed Susitna Station in 15 days between 15 July and 29 July.The
fishwheels at Susitna Station caught a total of 691 pink salmon.Of the
691 pinks caught,57.5 percent were intercepted by the west bank fishwheel
and 42.5 percent intercepted by the east bank fishwheel.Figure ED-4
indicates the peak of migration occurred between 21 July and 3 August.
At Yentna Station,36,053 pink salmon we~e enumerated by sonar counters.
The south bank sonar counter recorded 82 percent of the counts while 18
percent were registered by the north bank sonar counter.The beginning,
mid-point and end of the migration approximately occurred on 14 July,27
July and 20 August respectively (Figure E.5.9).Seventy-five percent of
the pink salmon were counted in 13 days between 21 July and 2 August.
The two fishwheels located at Yentna Station intercepted 2,729 pink
salmon.Sixty-three and seven tenths percent of the pink salmon were
intercepted by the south bank fishwheel and 36.8 percent were cau~ht by
the north bank fishwheel.A graphic representation of the fishwheel
catctl per hour indicates that the peak of the migration was during the
17 days between 21 July and 6 August (Figure ED-4).

At Sunshine Station SSS counters enumerated 72,945 pink salmon.Eighty~
four and five-tenths percent of the counts were registered on the east
side of the river and 15.5 percent on the west side of the river.The
migration essentially began on 23 July,~eaked on 1 August and terminated
on 20 August (E.5.9).Seventy five percent of the fish were counted in
13 days from 28 July to 9 August.Sunshine Station operated four fishwheels;
two on the west bank and two on the east bank of the Susitna River.A
combined total of 7,099 pink salmon were caught with the east bank
fishwhee1s intercepting 91.3 percent and the west bank fishwheels catching
the remaining 8.7 percent.Figure ED~5,a plot of fishwhee1 catch per
hour,shows the peak of migration occurred between 29 July and 9 August.
Talkeetna Station counted 2,529 pink salmon.Fifty-seven and three-
tenths'percent of the counts were recorded by the west bank sonar and
42.7 percent by the east bank sonar.The migration principally began on
27 July,reached a midpoint on 6 August and terminated on 20 August
(Figure E.5.9).Seventy-five percent of the escapement was intercepted
between 29 July and 9 August.The four fishwhee1s operating at Talkeetna
Station intercepted a total of 379 pink salmon.Fifty-nine point four
percent were caught by the east bank fishwhee1s and 40.6 were caught by
the west bank fishwhee1s.Figure ED-5 graphically illustrates that peak
fish ....'hee1 catches of pink salmon occurred between 1 August and 10 August.
The pink salmon migration at Curry station started on 31 July,reached a
midpoint on 8 August and terminated 19 August approximately (Figure ED-
6).Seventy five percent of the escapement passed the site between 4
E - 5 - 2 6
August and 19 August.The majority of the pink salmon fishwheel catch
(69.9 percentl at Curry Station was made on the east side of the river.
Population est1mate~derived from tag and recapture data indicate that
48,459 pink salmon were present at Sunshine Station,2,574 ~resent at
Talkeetna Station and 1,052 present at Curry Station.The 95%confidence
limits along with the parameters used to calculate these estimates are
presented in Table E.5.3.
The migrational rate based on plots of sonar and fishwheel catch data
indicate that pink salmon took an average of three days to reach Yentna
Station from Susitna Station,a distance of approximately six miles
(Figure E.5.5 and ED-5).This represents an average travel of about 2.0
miles per day.These travel rates are valid only if there is no fundamental
variation in migrational timing between Susitna River pink salmon stocks.
Pink salmon averaged of about nine days of travel time between Susitna
Station and Sunshine Station (Figure E.5.5).This represents an average
travel rate of 6.0 miles/day.Travel time between Susitna Station and
Talkeetna Station was approximately 12 days or a travel speed of 6.4
miles/day.
Tag and recapture data on pink salmon indicate that travel time between
Sunshine Station and Talkeetna Station ranged from two to 30 days (Figure
E.5.6).Pink salmon averaged three days of travel time or six miles/day
between Talkeetna Station and Curry Station with a range of one to 13
days (Figure E.5.71.

The average length of male pink salmon at Susitna Station was 444mm,
478mm at Yentna Station.445mm at Sunshine and 432mm at Curry Station.
In comparison females averaged 433mm.471mm.449mm,434mm,and 432mm in
the same order by station.The data indicates that pink salmon stocks
in the Yentna River subdrainage were larger than the pink salmon stocks
utilizing the Susitna River upstream of the Yentna River confluence
(Table EF-24).
Table E.5.7 summarizes the sex composition of pink salmon sampled from
fishwheel catches at each of the stations.Male pink salmon were more
abundant than females at all sampling stations except at Talkeetna
Station where females were 20 percent more numerous (1:1.2)than males.

the east bank.
The Yentna Station SSS counters enumerated 19,J65 chum salmon.Sixty~
four and four-tenths percent of the counts were recorded by the south
bank sonar and 35.6 percent by the north bank sonar.The chum salmon
migration essentially began at Yentna Station on 13 July,reached a mid~
point on 29 July and terminated on 24 August (Figure E.5.101.Seventy
five percent of the fish were counted in a 29 day period between 18 July
and 15 August.Fishwheels operated at Yentna Station caught a total of
1,415 chum salmon.Chum ~a1mon passage by Yentna Station reached a peak
between 20 July and 23 July as indicated by fishwheel catch data (Figure
ED-7).The north and south bank fishwheel chum catches during this
period were 66.3 percent and 33.7 percent respectively.
Side scan sonar counters at Sunshine Station counted 59,630 chum salmon.
The E!ast bank counter recorded 77.9 percent of counts and the remainder,
22.1 percent,were registered on the west bank counter.The chum salmon
migration began on 22 July,reached a mid-point on 6 August and terminated
on 6 September,approximately (Figure E.5.10).Seventy five percent of
the fish were counted in a 29 day period between 27 July and 24 August.
A total of 9,167 chum salmon were caught in the four fishwhee1s at
Sunshine Station.The peak of chum salmon migration at Sunshine Station,
as indicated by daily fishwheel catches,occurred between 17 August and
19 August (Figure ED-8).The east bank fishwhee1s intercepted more chum
salmon than the west bank wheels by the ratio of 9.1 :1.
A total of 10,036 chum salmon were counted at Talkeetna Station.The
west bank SSS counted 59.6 percent of the chum salmon and 40.4 percent

were enumerated on the east bank SSS,The migration approximately began
on 28 July~reached a mid~point on 8 August and ended on 29 August
(fi gUire E,5.101.Seventy-five percent of the escapement was counted in
a 32 day period between 30 July and 30 August.A total of 1 ,285 chum
salmcln were intercepted by the fishwheels at Talkeetna Station.Seventy~
five percent were caught between 4 August and 7 September with 48.7
perCE!nt and 51.3 percent of the total catch intercepted on the east and
west bank respectively (Figure ED~81.
Fish~/heel catches at Curry Station indicate that the migration essentially
began on 29 July,reached a mid-point on 16 August and terminated on 2
September (Figure ED-g).The majority (89.6%)of the catch made on the
east side of the river.
Tag 2lnd recapture data indicates that 256,667 chum salmon were present
at Sunshine Station~20~244 at Talkeetna Station and 12,934 at Curry
Station.The 95%confidence limits and variables used to calculate the
estimates are presented in Table E.5.3.
Chum salmon averaged four days of travel time between Susitna Station
and Yentna Station for a travel speed of 1.5 miles/day.The average
travel time between Susitna Station and Sunshine Station was ten days
which computes to a travel speed of 5.4 miles/day.The migration period
between Susitna Station and Talkeetna Station averaged 14 days or 5.5
miles/day.The migration timing and travel rates presented above are
considered valid if there is no fundamental variation in timing between
Susitna River chum salmon stocks.

Chum salmon tagged at Sunshine Station took between two and nine days to
reach Talkeetna Station (Figure E.5.61.Between Talkeetna Station and
Curry Station the number of travel days ranged from one to 24 days with
an average travel time of approximately 4.5 days and a mean travel speed
of 3.8 miles/day (Figure E.5.71.
Evaluation of the hourly passage rate of chum salmon at Sunshine Station
suggests a distinct behavior pattern with a high percentage of the fish
passing the counters between 2100 hours and 0100 hours and between 0300
hours and 0500 hours (Figure E.5.ll}.The lowest hourly passage rate
occurred between 0700 hours and 1100 hours.East bank SSS sector counts
at Sunshine Station indicate that chum salmon displayed a strong migrational
preference for near-shore travel.More than 60 percent of the chum
salmon were counted in the first sonar sector and 30 percent in the
second sector (Figure E.5.4).Comparison data is not available for the
other stations due to the absence of discrete periods when chum salmon
comprised 90 percent or more of the counts.
Table E.5.8 outlines the age structure of the chum salmon sampled at
each of the stations.Age 41 chum salmon from the 1977 brood year
dominated the catch at each site comprisinq an average of 86 percent of
the fish.Next abundant were age 51 fish followed by age 31 fish which
made up ten percent and four percent of the age samples respectively.
The most notable difference in age class structure was among the chum
salmon sampled at Curry Station which were 14.1 percent and 1.9 percent
age 51 and 31 fish respectively.This is a considerable variation from
the above cited averages for the combined stations.

salmon had an average length of 593mm,601mm,624mm,586mm,and 593mm at
Susitna,Yentna,Sunshine,Talkeetna and Curry stations respectively.
Female chum salmon of the same age at the same lncations had an average
length of 581mm,585mm,588nnn,578mm,and 614mm respectively.
Table E.5.9 provides a comparison of sex ratios between age classes by
sampling location.Combined age class sex ratios indicate that male
chum salmon were less abundant than females at Susitna Station (1 :1.6)
and Sunshine Station (1 :1.2)and equally numerous as males at Yentna
Station (1 :1).Male chum salmon were dominate at Talkeetna Station
(1 :0.7)and Curry Station (1 :0.9).
Coho Salmon
A total of 33,470 coho salmon were enumerated across the SSS counters at

a total of 329 coho salmon.Coho salmon showed a strong bank preference
with 76.3 percent moving up the west bank and 23.7 percent migrating
along the east bank.A plot of fishwheel catch per hour indicates the
~eak of migration occurred between 25 July and 30 July
(Figure EO-101.
The Yentna Station SSS counters enumerated a total of 17,017 coho salmon.
The south bank counter registered 83.6 percent of the count and the
north bank counter registered 16.4 percent of the count.The migration
principally began on 22 July,reached a mid-point on 31 July and ended
on 20 August (Figure E.5.l2).Seventy five percent of the fish passed
between 23 July and 16 August.A total of 1,122 coho were intercepted
by Yentna Station fishwheels with 75.7 percent and 24.3 percent of the
catch caught along the south and north bank respectively.The peak of
migration,as shown by a plot of fishwheel catch per hour,occurred
between 23 July and 6 August (Figure EO-10).
Side Scan Sonar counters at Sunshine Station counted a total of 22,793
coho salmon.Sixty-six and six-tenths percent of the fish passed over
the west bank sonar and the remaining 33.4 percent over the east bank
sonar.The migration principally began at Sunshine Station on 29 July,
reached a mid-point on 18 August and terminated on 5 September,approximately
(Figure E.5.12).Seventy five percent of the migration was counted in
21 days from 4 August to 24 August.Sunshine Station fishwhee1s intercepted
2,928 coho salmon.There was no apparent preference between river banks
with 51.6 percent and 48.4 percent migrating up the east and west bank
respectively.A plot of the fishwheel catch per hour graphically
E - 5 - 3 8
illustrates that coho salmon passage peaked between 18 August qnd 25
August (Figure EO~lll,
The SSS counters at Talkeetna Station recorded a total of 3,522 coho
salmon.The west bank sonar enumerated 62.0 percent of the fish and the
east bank sonar,38 percent.The migration approximately began,reached
a mid-point,and ended on 30 July,24 August and 11 September respectively
(Figure E.5.12).Seventy five percent of the coho salmon were counted
in 22 days fronl 11 Auqust to 1 September.The four fishwheels operated
at Talkeetna Station intercepted a total of 533 coho salmon with 59.5
percent caught in the two west bank fishwheels.Fishwheel catch per
hour plots indicate that the peak of migration occurred between 19
August and 30 August (Figure ED-ll).
Curry Station fishwheel catches indicate that the coho salmon migration
f..,'.,
began,reached a mid-point and ended on 5 August,22 Auqust and 4 September
respectively (Figure EO-12).The majority (64.8%)of the fish at Curry
Station were intercepted on the east side of the river.
Population estimates derived from tagging and recapture operations
indicate that 24,416 coho salmon were present at Sunshine Station,3,291
were present at Talkeetna Station and 1,164 were present at Curry Station.
The parameters used to calculate the estimates along with the 95%confidence
limits are presented in Table E.5.3.
The average migrational travel time between Susitna Station and Yentna
Station was two days which is an upstream travel speed of 3.0 miles/day
E - 5 - 3 9
(Figure E.5.5}.Fourteen days were spent between Susitna Station and
Sunshine Station.The total travel time from Sus.;tna Station beyond
Sunshine Station to Talkeetna Station was approximately 24 days.This
represents a travel rate of 3.9 and 3.2 miles/day respectively.These
migration rates are based on the assum~tion that there is no fundamental
variation in timing between Susitna River coho salmon stocks.
Tag recaptures of marked coho salmon from Talkeetna Station at Curry
Station indicate that coho salmon migrated between these stations in two
to 15 days (Figure E.5.7).The average travel time was 4.5 days or a
travel speed of 3.8 miles/day.
Table E.5.10 summarizes the coho salmon age composition by sampling
location.The data indicates that the majority of the fish were age 43
from the 1977 brood year followed by age 32 from the 1978 brood year.
Less than ten percent of ·the coho"escapement was compri sed of other a~e
classes.
A summary of coho salmon lengths (FL)collected by sampling station is
presented in Table E.5.11.This data is also graphically displayed in
Figures EF-16 through EF-20 and Figures EF-28 through EF-30.Lengths
ranged from 216mm to 645mm at Susitna Station,365mm to 635mm at Yentna
Station,325mm to 680mm at Sunshine Station,320mm to 650mm at Talkeetna
Station and 370mm to 605mm at Curry Station.The average lengths of

5.2 Survey Investigations
Mainstem Surveys
Presented in Table EG-l is a list of the locations and catch results of
more than 300 sites sampled with gill nets and electroshocking gear on
Susitna River mainstem.Twelve mainstem spawning locations were identified
(Table E.5.l2).Chum salmon were found spawning at 10 of 12 sites.
Coho salmon were found spawning alone at one site and both coho and chum
salmon were recorded sharing spawning sites in two mainstem areas.One
of the 12 spawning areas was located at RM 100.5.This site was determined
on the basis of visual sightings of redds on 24 September and egg deposition
sampling on 30 October.Salmon eggs were found in subsurface gravels at
the same site,but it was not possible to confirm which species spawned
there.Maps of each of the 12 spawning areas are presented in Fi9ures
EH-l through EH-12.All spawning areas are located between RM 68.3 and
RM 135.2.
Echo recorders did not prove effective in identifying mainstem spawning
areas.They were tested in mainstem sloughs and although adult fish
were located through vertical scanning,interception of recorder print-

outs on the mainstem Susitna River was difficult because debris echoes
had a similar appearance to fish and turbulence produced false recordings.
Further compounding the problem was the inability to operate echo recorders
against the force of the river current.The gunnel mounted transducer
brack·ets commonly bent and become inoperative particularly in areas
where water velocity was greater than three feet per second.
Drift gill nets were effective in locating five of the 12 mainstem
spawning sites previously referenced.They were not however,considered
an efficient means of sampling due to variable water depths encountered.
Many areas were several meters deeper than the 1.5 m depth limit of the
nets.In shallower areas,debris caused nets to be torn and resulted in
several hours of mending for each hour fished.
Electroshocking gear was not available to the survey crews operating
.'~..'.""~
above RM 61 until 21 September.Although only one mainstem spawning
site was found with this gear type,it worked efficiently in all areas
of the river in which it was used and was considered superior to drift
gill nets and depth recorders.It is probable that additional spawning
areas would have been located had the gear been used earlier in the
season particularly in late August and early September.
Results of set netting in the area immediately below Devil Canyon between
RM 150.1 and 150.4 (Figure E.5.13)are presented in Table E.5.13.The
data confirms that sockeye,chum and coho salmon used the Susitna River
mainstem above portage Creek for migration purposes.A catch comprised
of sockeye,chum and coho salmon was made on 26 August at RM 150.2 and a

sing"le cOho salmon was captured on 2 September at RM 150.4.All gill
nettE:d fish were in pre spawning condition.The one coho ~almon caught
on 26 August had been tagged earlier at Talkeetna Station on ]August.
Set netting conducted between 29 July and 5 August and also from 25
September to 19 September did not produce fish.No set netting was
performed between 6 August and 25 August due to high water conditions.
Escapement Surveys
Escapement surveys were conducted on 32 sloughs and 15 tributary streams
of the Susitna River reach between the Chulitna River and Devil Canyon
(Figure E.5.14).Eight new sloughs and streams were located which
supported salmon spawning.The sloughs are referenced as Moose (RM
123.5),A1 (RM 124.6),98 (RM 124.2)and 21A (RM 145.5).The new streams
are Gash Creek (RM 111.6),Lower McKenzie Creek (RM 116.2),5th July
",-.-....::..'"",.
Creek (RM 123.7)and Jack Long Creek (RM 144.5).The location of these
streams and sloughs relative to the Susitna River mainstem are defined
in Figure.
Adult sockeye salmon were observed in Sloughs 38,3A,6A,SA,9,9A,98,
11,17,19,20 and 21 and in Lower McKenzie Creek (Tables EJ-l through
EJ-2).Peak spawning occurred during the last week of August and the
first three weeks of September (Figures E.5.15 through E.5.17).Sockeye
salmon were most numerous in Slough 8A,98 and 11 where peak spawning
ground counts were 177,81,and 893 sockeye salmon respectively.

Pink salmon were found in Sloughs 3A~8 and A,also in Whiskers Creek~
Chase Creek~Lane Creek,Fourth July Creek,5th July Creek,Skull Creek,
Sherman Creek,Indian River and Jack Long Creek (Tables EJ ...1 and EJ-2).
The highest peak sfjawning count within an index area was in Lane Creek
where 291 fish were recorded.Peak spawning occurred in a ten day
period from 19 August to 28 August (Figure E.5.18).The stream survey
counts are index counts and do not reflect total number of spawning fish
present in the stream surveyed.

July Creek and Indian River (Table EJ-2).The peak of spawning activity
in the sloughs occurred during the 1as~two weeks of August and the
first two weeks of September-(Figures E.5.15 through E.5.17).The
highest counts were recorded in Sloughs 8,8A,9,11 and 21 where 302,
620,.260,411 and 274 chum salmon,respectively were found spawning
(Figure E.5.19).Based on the limited stream survey data the peak
spawning period was approximately one week earlier than that observed in
slough spawning areas.The highest peak count in an index area was
registered on Lane Creek where 76 chum salmon were counted on 23 August
(Figu:re E.5.18).
Coho salmon were not found in any of the sloughs surveyed but were
observed in Whiskers Creek,Chase Creek,Lane Creek,Gash Creek,Lower

EJ~l and EJ~21,The highest densities of coho salmon,based on pe~k
index counts,were in Whiskers Creek,Chase Creek,Gash Creek and tndian
River where 70,80,141,and 85 coho salmon respectively were recorded
spawning in a single survey.The survey data indicates that the spawning
peak probably occurred in the second and third week of September.
5.3 Radio Telemetry Investigations
Chum Salmon
Eleven chum salmon were radio tagged between 30 July and 12 August and
their movements monitored during 30 and 31 July and August,1981 (Table
E.5.l4).Ten of of the 11 fish were tagged between 6 and 12 August.
Seven fish were tagged at Curry Station and four were tagged at Talkeetna
Station;five-were females-and six were males (Figure E.5.20).
Eight of the radio tagged chum salmon moved upstream from their respective
tagging locations.Two others moved downstream and one remained within
+0.2 river miles of its tagging location (Figure E.5.2l.)
Radio tagged chum salmon that moved upstream after tagging exhibited two
types of movement.Upstream movement,with cessations of less than 72
hours was termed "direct movement".Upstream movement with cessations
in excess of 72 hours,was termed,"indirect movement".
Direct movement was exhibited by chum salmon bearing transmitters numbered
650-3,680-2 and 710-2 (Figure E.5.2l}.Indirect movement was displayed

by fi~h bearing transmitters numbered 660-1,680-3 and 720-1.Fish
bearing transmitters numbered 680-3 and ]20-1 remained in the Susitna
River within 0.3 mile of the mouth of Fourth July Creek (RM 131 .O}for
three and 11 days respectively,and fish carrying transmitter number
660-1 remained at the mouth of Lane Creek (RM 113.6)for at least six
days.
The f"ive remaining radio tagged chum salmon exhibited other movements
(FigU1"'e E.5.2l).Two individuals bearing transmitters numbered 700-1 and
700-3 moved downriver,the first individual entered a slough at RM 96.9
whereas the other chum salmon ascended the Chulitna River.Fish bearing
transmitter number 670-2 remained within 0.2 miles of its tagging location
at RM 119.5.A chum salmon carrying transmitter number 730-2 was last
detected at RM 127.0.
A female chum salmon regurgitated transmitter number 740-1 at RM 121.1
several days after being tagged 1.6 miles downriver but was detected
spawning without it's radio transmitter in Slough 11 (RM 135.3).
Determination of radio tagged,chum salmon upstream,migration rates was
influenced by the time separating consecutive tracking detections.
Eighteen percent of the detections,e.g.location of a fish 1 s positions
in the river,were made within a frequency of 24 hours or less while 43
percent were made with a frequency of between 24 and 48 hours.Because
of these relatively long intervals and because exact arrival times at
upstream locations are unknown,the movement rates,with few exceptions,
are expressed as "greater than or equal to"(2 }speeds.
E - 5 - 6 3
The fastest documented rate of chum salmon migration was 1.0 miles per
hour (mph}CTab1e £.5.lSi.Fish bearing transmitter number ]10~2 moved
1.9 miles upstream within 1.9 hours after release.Perhaps more typical
of sustained rapid movement is the subsequent movement of this fish when
it traveled 22.2 miles within 32.5 hours for a rate .2:0.68 mph or 16.4
miles/day.In contrast,fish bearing transmitter number 650~3 moved 5.1
miles within 39 hours for a rate .2:0.13 mph or 3.1 miles/day.
Rates of movement of two radio tagged chum salmon which migrated lIdirectly"
upstream suggest that radio tag implantation did not interfere with
their upstream migration as their rates of movement were similar to that
exhibited by some Flay tagged chum salmon.Two chum salmon radio tagqed
at Talkeetna Station on 6 August reached Curry Station within two days.
Fish bearing transmitter number 730-2 was detected 0.3 miles upriver of
Curry Station 48 hours after being ~adio tagged at Talkeetna Station.
Another chum salmon,supporting transmitter number 710-2,9.2 miles
upriver of Curry Station,51 hours following transmitter implantation at
TalkE!etna Station.One hundred six chum salmon tagged with Flay tags at
Talkeetna Station were recaptured by fishwhee1s at Curry Station 16.5
river miles upriver.Twenty of the 106 fish were recaptured after one
day Clf release,42 after two days,53 after three days,74 after four
days and 86 after five days.The number of recaptures progressively
decreased each day until 106 recaptures were recorded.
The influence of flow on the movements of radio tagged chum salmon in
the Susitna River is not apparent due to the small number of chum salmon
tagged,and the limited flow conditions encountered by these fish (figure

The p'rimary destinations of radio tagged churn salmon were Susitna River
sloughs,clear water tributaries and the confluence zones of tributary
streams (Figure E.5.211.The four fish bearing transmitter numbers 66Q~

three fish bearing transmitter numbers 650 ..3,680-2 and 680~3 entered
the Indian River CRM 138.9}.One fish bearing transmitter number 720~1
entered Sherman Creek (RM 130.8)before returning to the mainstem Susitna
River where it held within 0.3 miles of the Fourth July Creek confluence
zone (RM 131 .O}.One fish bearing transmitter number 670-2 stayed in
the mainstem Susitna River at RM 119.6.One fish bearing transmitter
number 700-3 swam down the Susitna River and entered the Chulitna River
(RM ~B.6).Fish bearing transmitter 730~2 was last detected at RM 127.0
in the Sus itna Ri ver...
Radio tagged chum salmon entered spawning areas between 8 August and 23
August.Fish bearing transmitter number 710-2 entered SloU9h 11 (RM
135.5)about 13 August and was observed building a redd on 21 August.
It had completed spawning by 2 September when it was captured and necropsied.
Fish bearing transmitter number 740-1 entered Moose Slou9h (RM 123.5)
between 13 August and 18 August.On 29 August it was observed over a
redd and netted.A brief external examination revealed that most eggs
were still present in the body cavity although the transmitter was
absent.The transmitter had been found earlier at RM 121.1,the site of
apparent regurgitation.On 4 September the carcass of this fish was
E - 5 - 6 6
found in Moose Slough.A necropsy indicated the fish had spawned,as
evidenced by the lack of eggs in the coelom.
rndiv"idualmo-vements of radio tagged chum salmon are described in Appendix
EK.
COho Salmon
Ten coho salmon were radio tagged from 31 August through 4 September.
Four were tagged at Curry Station and six at Talkeetna Station (Table
E.5.l6}.Eight bore wire reinforced radio transmitters whereas two
carried non-reinforced transmitters (660-2 and 680-l).Coho salmon
displayed three types of directional movement:downstream,upstream or
milti-directional movement (Figure E.5.22).
.,
Three radio tagged coho salmon from Talkeetna Station and one from Curry
Station moved downriver upon release.Three of the four fish entered
tributaries downstream of RM 102.8 of the Susitna River (Figure E.5.22).
Fish supporting transmitter number 700-2 entered the Chulitna River (RM
98.6}and moved upstream to RM 31.9.Another individual bearinq transmitter
number 710-1 entered the Talkeetna River and acended Chunilna Creek (RM
5.9)where it was last detected at Chunilna Creek mile 9.1.Fish carrying
transmitter number 710-3 moved downstream in the Susitna River to RM
88.0 and ascended Birch Creek (RM 88.0)to Fish Lake and spawned in an
inlet stream.The fourth fish,supporting transmitter number 720-2,was
apparently adversely influenced by transmitter implantation as evidenced
by observations of the fish while it occupied Chase Creek (RM 106.91.

Length of stay of the above three radio t~gged coho salmon in the Susitna
River upstream of RM 100.1 was variable;a fish bearing transmitter
number 700-2 moved downstream to Whiskers Creek (RM 101.21 and remained
there for several days prior to moving further downstream and ascending
the Chulitna River.The other two fish su~portin9 transmitter numbers
710-1 and 710-3 moved downriver after tagging.
Two coho salmon tagged at Talkeetna Station bearing transmitter numbers
650-2 and 730-3 exhibited upstream movement after ta~ging.The fish
Iwithtransmitternumber650-2 entered Indian River (RM 138.6)eight days
after tagging and the fish with transmitter number 730-3 remained at the
mouth of Fourth July Creek (RM 131.0)for several weeks before moving up
the creek.Both fish were implanted with transmitters having modified
antennas.
Four coHd salmon tagged at Curry Station exhibited multi-directional
movements in the Susitna River (Figure E.5.22).Two fish carrying
transmitter numbers 650-1 and 660-2,entered and spawned in Gash Creek
(RM 111.6).Fish bearing transmitter number 650-1 moved downstream and
remained in the Talkeetna River (RM '97.0)prior to moving up the Susitna
River and entering Gash Creek (RM 111.6)whereas fish supporting transmitter
number 660-2 moved upriver to RM 141.1 then descended to and entered
Gash Creek (RM 111.6).Another coho salmon supporting transmitter
number 680-1 moved downriver to RM 101.5 and held there for several days
before migrating upstream to RM 109.8 where transmitter reception was
lost..The other fish bearing transmitter number 720-3,moved upriver to
RM 131.0,then descended to and remained at RM 117.8,near the mouth of
E - 5 - 7 a
Little Portage Creek,through early October and apparently did not
spawn.
Moveml=nts of coho salmon apparently were not "influenced by flow conditions
wHhin the SusHna River (Figure £.5.22).Flows'decreased from about
23,000 cfs in late August to 11 ,000 cfs in mid~September.
Adult,radio tagged coho salmon moved upstream at various rates,although
the rl=latively long periods of time separating some successive fish
posit-ions probably under-estimated the upstream migration rates (Table
E.5.l7),The fastest upstream migration rates,0.67 to 1.00 mph,generally
occurred at intervals of less than five hours.However some coho salmon
moved upstream at 0.23 to 0.60 mph during longer intervals of 20 to 60.8
hours.Consequently,all upstream migration rates are expressed as
equa 1 to or exceed"j ng (~),except for those success ive fi sh pos iti ons
separated by less than five hours.'
Behavior of adult radio tagged coho salmon near the mouths of Susitna
River tributaries was variable (Fiqure E.5.22).Some individuals,such
as fish bearing transmitter numbers 650-1 and 660-2,occupied positions
in the mainstem Susitna River at or within 0.1 mile of the mouth of Gash
Creek (RM 111.6)for several days prior to entering that tributary.
Other coho salmon such as those carrying transmitter numbers 650-2 and
720-3,remained in the Susitna River within 0.1 mile of the mouth of
Fourth July Creek (RM l31.0)and Little Portage Creek (RM 11].8),respectively,
for two or more weeks.Fish bearing transmitter number 650~2 entered
Fourth July Creek after holding at it's mouth for about two weeks whereas

fish bearing transmitter number 720~2 remained near little Portage Creek
(RM 1·17.8}for about three weeks and apparently did not ascend that
stream.
Three radio tagged female coho salmon spawned in streams connected to
lakes as evidenced by their spawned out condition upon necropsy.However.
actual spawning activity was not observed.Two spawned out individuals
supporting transmitter numbers 650-1 and 660-2 were detected in Gash
Creek (RM 111.6);one carried a wire modified transmitter whereas the
other supported the heat-to-shrink material style transmitter.The
other fish bearing transmitter number 710-3 spawned in Cabin Creek a
tributary of Fish Lake (RM 4.7 Birch Creek)and bore a wire modified
transmitter.
The ab?ve thr~e individuals spawned within one week after entering
Susitna River tributaries in September.A female fish bearing transmitter
number 710-3 was found spawned out and dead less than one week after
entering Cabin Creek (RM 4.7 Birch Creek)in September.Two fish bearing
transmitter numbers 660-2 and 650-1.were detected in a spawned out
condition within seven days after entering Gash Creek (RM 111.6)on
about 22 and 21 September.respectively.
A female coho salmon bearing transmitter number 650-2 displayed a similar
pattern of tributary occupancy in Fourth July Creek (RM 131.0).This
individual entered the stream on 20 September after remaining in the
Susitna River near the mouth of this stream for about two weeks.It was
detected at RM 1.25 Fourth July Creek lRM 131.0)on 20 September.On 23
E - 5 - 7 3
September it was detected in the Susitna River at RM 130.0.The spawning
status of this fish was not determined.
Individual movements of radio tagged coho salmon are further described
in Appendi-x EK.
Other telemetry studies have detected radio transmitter regurgitation
amongl adult coho salmon and steel head trout,sa1mo qairdneri.Two of
twenty three adult coho salmon evidently regurgitated radio transmitters
(identical in dimension to those used in this study but without antenna
modifications)downstream of their release sites.along the White River,
Puget Sound,Washington (personal communication,Don Chapman).Location
of the transmitters remained static during the White River study whereas
had they been within carcasses they probably would have moved downstream.
The transmitters were lubricated and esophagea11y implanted with the
~:~
antenna trailing through the operculum rather than being anchored to the
roof of the mouth or kype,as they were in the Susitna River study.
ThreE!adult steel head trout in the Clearwater River,Idaho a1 so were
presumed to have regurgitated transmitters,measuring 9.7 cm long and
1.2 em in diameter.They were presumedly regurgitated in the spring,in
response to development and expansion of the gonads prior to spawning
(personal communication,Steven Pettit).The antenna of each transmitter
was anchored to the roof of the fish's mouth.Another individual was
captured with the transmitter dangling from the mouth,suspended by the
antenna.

Chum Salmon,Radio Transmitter #650-3
This Inale chum salmon was radio tagged at river mile (RM)119.5 on
7 August (Figure EK-l).Within 33.5 hours of tagging the chum salmon
moved 14.3 miles upstream,at a rate greater than or equal to
(»0 ..43 miles per hour (mph).During the next 39 hours the fish moved
an additional 5.1 miles upstream to a position 0.3 miles above the
Indi~l River confluence (RM 138.6).Sometime during the following three
days 1:he fish entered the Indian River (RM 138.6)where it was found
1.3 miles above the confluence on 13 August.It remaineA in the Ir.d·an
River between RM 2.1 and 0.6 for the remainder of the season,fifteen
tracking flights.
Chum Salmon,Radio Transmitter #660-1
On 10 August this male chum salmon was radio ~agged at RM 102.9
(Figure EK-2).Within several hours this fish moved 1.9 miles downriver.
Nineteen and six tenths (19.6)hours later,however,it had moved
8 milE~s upstream.This upstream movement was ~0.41 mph.During the
next eight hours the fish_moved downstream about 0.8 mile.Wi thin
fifteen hours it had resumed upstream migration and was detected 5.4
miles upstream,at the mouth of Lane Creek (RM 113.6).The salmon
remained there for at least three days and then began moving upstream.
Sixty one hours later,on 18 August,it was found at RM 123.3;this
upstream movement was ~0.16 mph.Within five days it had proceeded
18.7 miles upstream to the head of Slough 21 (RM 142.0),movement to
this location occurred at a rate>0.15 mph.Aerial surveys on 26 and
28 August indicated the fish was moving down Slough 21.On 30 August

Slough 21 was surveyed by foot.The functional radio transmitter was
found about 20 feet from the water amongst the remains of the fish
carcass.This fish was apparently captured by a predator.
Chum Salmon,Radio Transmitter #670-2
This female chum salmon was radio tagged on 12 August at RM 119.5
(Fi~~e EK-3).It displayed very little movement following release.
Withi.n 2.4 hours it moved 0.2 miles upstream.Almost 21 hours later it
was found 0.8 miles upstream at RM 120.5.Two days later it had dropped
to ~[119.8,a position only 0.3 miles upstream from its release site.
Durin.g the remainder of the season and a total of 27 more tracking fixes
the fish stayed between RM 119.9 and 119.6.During this time it periodically
moved between the east and west banks.Several attempts to recover the
fish failed.

Chum Salmon,Radio Transmitter #680-2
On 6 August this male chum salmon was radio tagged at RM 120.7
(Figure EK-4).Immediately upon release this chum salmon moved downriver;
wi thin 45 minutes it was 0.1 mile downstream.Less than 2 days later
(42.5 hours),however,it had migrated 21.3 miles upstream to a position
3.3 miles up the Indian River (RM 138.6).Movement rate to this location
was>0.50 mph.For the next ten days the fish was found between Indian
River mile 3.3 and 2.4.On 23 August it had moved downstream to Indian
RM1.7.For the remainder of the season it was found between RM 1.8
and 1.1 of the Indian River.

Chum Salmon,Radio Transmitter #680-3
On 9 .~ugust this male chum salmon was radio tagged at RM 119.5
(Fi~re EK-5).Within 17.3 hours following transmitter insertion,
the fish moved 4.2 miles upstream to RM 123.7 for a movement rate
~.0.24 ",ph.I:~or at least 'cb.e ney~t:30 hours it held position at RM 123.7.
On 13 August it was found approximately 1.3 miles upriver of Four~~July
Creek (RM 131.0)at RM 132.3 along the west shore of the Susitna River.
Moveml~nt to this location was:0.18 mph.It then moved downstream to
within.0.05 miles of the mouth of Fourth July Creek (RM 131.0)and
remain.ed there about six days.Sometime after 1100 hours on 21 August
the fish began moving upstream.On 23 August it was located in the
Indian River about one half mile above the confluence with the Susitna
River (RM 138.6).Movement rate to this location was:0.172 mph.The
fish stayed in the Indian River approximately one week and was consistently

confluence,about 20 miles downriver from its last known position.By
31 August the fish had moved into Slough S-14 (RM 96.9)on the west side
.of the Chulitna-Susitna confluence area.On 8 September the transmitter
was recovered from the car·::ass along the ba.'rJ.k.of Sloug1:1 S-~4,located at
RM 96.9.Spawning condition could not be det2~mined due to the-adval'1c2d
state of carcass decomposition.
Chum Salmon,Radio Transmitter #700-3
On 3 July this female chum salmon was radio tagged at RM 102.9
(Figure EK-7).After tagging this fish moved downstream and remained in
the Susitna River at RM 99.5,just above its confluence with the Chulitna
River,until 6 August,a period of about one week.It then moved into
the.Chulitn~River anq was found on 8.August,12.miles upriver of the
TRA.Movement during this time was>0.24 mph.Ten days later the fish
was found at RM 16.1 of the Chulitna River.During the remainder of the
season this fish could not be found,probably due to transmitter failure;
erratic transmitter signa~s were.detected during the 6 and 7 August
aerial tracking flights.
Chum Salmon,Radio Transmitter #710-2
Radio tagging of this female chum salmon occurred on 6 August at RM 102.9
(Figure EK-8).This fish displayed the most rapid upstream movement for

the radio transmitter,which was located at RM 121.1.Oft 4 September
the fish was found dead in Moose Slough.It was necropsied and determined
to be~spawned-out.The transmitter continued to emit weak signals at
RM 121.1 for the remainder of the season.Numerous attempts_to retrieve
the t:ag failed.
Complete radio-tagged chum salmon movement data are shown on Table EK-l.
Coho Salmon,Radio Transmitter #650-1
Fish 650-1 was tagged on 3 September at RM 120.7 (Figure EK-12).This
coho salmon progressively moved downriver and eventually entered the
Talkeetna River between 4 and 11 September.Six hours after being
released it was detected.at RM 116.1.The following day,4 September at
l450h,it was located at RM 107.0;about 6 hours later it was detected
downriver at RM 102.5.An overflight on 11 September detected the fish
in the Talkeetna River (RM 97.0)at RM 2.7.Subsequent overflights on
the 13 and 16 September detected the individual at RM 2.7 and 3.2,
respectively.
Sometime between 16 and 18 September this coho salmon departed the
Talkeetna River (RM 97.0)and moved upstream the Susitna River.The
individual apparently remained in the Talkeetna River at or near RM 2.7
on 17 September,as it was not detected by boat while tracking round
~rip along the lower 0.75 mile of the Talkeetna River (RM 97.0)and the
Susitna River from RM 96.8 to 120.8.However,the next day,18 September,

it was monitored in the Susitna River adjacent to the mouth of Chase
Creek"(RM 106.9)and by 21 September was located in the east channel of
the Susitna River at RM IlLS,immediately downstream of Gash Creek,
(RM 11L 6)•
The fish \.,ras first detected in Gash Creek (RH Ill.6)at Pl'1 0.375 by
overflight on 23 September;later the same day,the fish was located by
telemE~try,during a stream survey,in a pond immediately above a beaver
dam a1t RM 0.375 with about 18 other adult coho salmon.Numerous attempts
to capture the individual with a net and assess it's spawning condition
were not successful.An overflight on 30 September did not locate the
fish.However,later that same day the spawned out,live female was
capt~red in a riffle-run stream reach ~river of the pond at RM 0.375.
The t:ransmi tter was missing.
A nec:ropsy was performed.It had spawned,as evidenced by the 18 eggs
retained in the coelum.
The ~{pe was torn where the transmitter wire modification had been
removl:!d by someone.The Peterson disc tag remained intact and no other
external injuries or abnormalities were noted.It is not known if
spawning took place prior to and/or after the removal of the transmitter.
Coho Salmon,Radio Transmitter #650-2
This individual was tagged at RM 102.9 on 1 September (Figure EK-13).
Ten minutes after release this fish entered (and was immediately removed
from)a fishwheel on the opposite bank at RM 102.8;forty ~inutes later

it was located upstream at RM 103.5.It was detected the following day
in Oxbow II at RM 119.3;this movement is equivalent to an upstream
migration rate ~0.56 mph or 13.4 mi/day.It reached RM 131.0 on or
before 5 September and remained wi thin 0.1 mile of the mouth of Fourth
of July Creek (RM 131.0)through at least 16 September.
Indirect evidence suggests this fish moved upstream Fourth July Creek
(RM 131.0)sometime during 17 or 18 September.It was consistently
detected by boat and airplane at RM 131.0 from 5 through 16 September.
However,on 18 September it was not encountered at or downstream of
RM 131.0 or along the lower 0.5 mile of Fourth July Creek (RM 131.0).Two
days later (20 September)it was detected by overflight at RM 1.25 Fourth
July Creek (RM 131.0).The individual probably would have been detected
on 18 September upriver of mile 0.5 of Fourth July Creek (RM 131.0)had the
ground telemetry survey extended further upstream.-Sometime between 20 and
23 September the fish departed this stream;it was last located in the
Susitna River at RM 130.2,downstream of the mouth of Fourth July Creek,
(RM 131.0),on 23 September.
Coho Salmon,Radio Transmitter #660-2
This I=oho salmon was radio tagged at RM 120.7 on 30 August (Figure EK-14).
Upon :r:elease the individual swam 0.1 mile upstream and remained there
for at least 45 minutes.However,the following day (36 hours later)
the fish was detected 11.0 miles downstream at RM 109.8;this movement
is equivalent to a downstream migration rate of about 0.35 mph.The
individual moved upstream to Oxbow I,RM 110.4,where it was monitored
durinq 1 and 2 September.

This individual began moving upstream sometime during 2 or 3 September
and IAras located at RM 141.1 on 8 September.This movement corresponds
to an overall upstream migration rate of 0.22 mph but the fish demonstrated
consi.derably faster upstream movement.For example,during 3 SepteIIl1Jer
it mClved upstream 2.2 miles in 2.5 hours,a rate >0.88 mph.
Somet.ime between 9 and 10 September the fish began mov:i..ng downriver and
entered Gash Creek,(RM 111.6),about 10 days later.On 10 September
the individual was located in Slough 6A at RM 112.5;this movement is
comparable to a downstream migration rate>0.53 mph.The fish exited
Slough 6A,as it was detected the following day at RM 113.3,and then
progressively-moved downriver and remained within 0.1 to 0.3 mile of the
mouth of Gash Creek during 17 and 18 September.It was detected at
RM 0•.1 Gash Creek (RM 111.6)on 20 September.
'.....----"
The fish was located by telemetry on 21 September at RM 0.2 Gash Creek
(RM Ill.6),netted and inspected.The transmitter was intact and the
fish had apparently spawned.The anterior one third of the coelomic
cavi~r appeared gravid and firm whereas the remainder of the coelom was
flacid and apparently devoid of eggs.The fish was returned to the
strea~nl alive,immediately swam 5 meters downriver and occupied an undercut
bank.
A 23 September overflight did not encounter the individual along Gash
Creek (RM 111.6);later the sarne day the live fish was detected visually
within 15 meters of it's release site,netted and inspected.The fish
was without the transmitter;neither telemetry or a search 25 meters up
E K 2 8
and downriver from the capture site detected the transmitter.It was
apparently removed from the fish sometime after 21 September.
A necropsy revealed only 25 eggs in the coelom.The stomach was intact
and displayed no apparent damage from the transmitter.
Coho Salmon,Radio Transmitter #680-1
Coho salmon number 680-1 was radio tagged at RM 120.7 on 31 August
(Figure EK-15).Forty five minutes after being released it had moved
upstream 0.1 mile but within 8.1 hours it was detected 13.6 miles downriver
at RM 107.2.This movement is equivalent to a downstream migration rate
~1.69 mph.The fish continued moving downriver to RM 101.9,where it
was monitored on 3 September.The coho salmon was consistently encountered
in the.Susitna River from RM 101.6 to.~~2.l through 1045h 10 ~epternber.'.
as determined by telemetry on 3,4,5,8,9 and 10 September.
The individual began moving upstream sometime between 1045h and 1950h on
10 September an.d was last detected at RM 109.7 on 11 September (1600h).
This upstream movement represents an upstream migration rate ~0.28 mph
or 6.7 mi/day.Extensive tracking efforts during the remainder of the
season failed to locate this fish.
Coho Salmon,Radio Transmitter #700-2
Fish 700-2 was tagged at RM 102.9 on 3 September (Figure EK~16).This
fish moved downstream to the mouth of Whiskers Slough,(RM 101.2),
within four hours of release,and remained there thru 5 September.It

was next detected at RM 25.9 Chulitna River (RM 98.6)on 11 September.
Overflights detected this individual at or within 0.3 miles of RM 32.1
Chulitna River (RM 98.6)on the 13,16 and 30 September.
Coho Salmon,Radio Transmitter #710-1
This fish was radio tagged at RM 102.9 on 4 September and remained undetected
until 8 September,when it was located in the Talkeetna River (RM 97.0)at
the mouth of Chunilna Creek,(RM 5.9)(Figure EK-17).Flights on 11 and
13 September detected the individual at RM 9.0 Chunilna Creek.It was not-
located thereafter.
Coho Salmon,Radio Transmitter #710-3
This female coho salmon was radio tagged at RM 102.8 on 4 September
(Figure EK-18):--Within 7.1 hours after being released this fish was
detected 1.7 miles downriver at RM 101.1.It was next detected 9 days
later by airplane in Fish Lake,about 4.7 miles upriver of the mouth of
Birch Creek,(RM 88.0).The individual ascended a northwest side inlet
(Cabin Creek)to Fish Lake,sometime between 13 and 16 September and remained
at or near RM 0.1 of this stream thru 19 September.A 19 September ground
telemetry survey detected the spawned-out,dead coho salmon at RM 0.1
Cabin Creek.The caudal fin of the female fish was worm.About 25 eggs
remained inside the fish.The stomach was ruptured along its entire length,
probably from the radio transmitter;no other apparent tissue or organ damage
associated with the radio transmitter was noted.

Coho Salmon,Radio Transmitter #720-2
This male coho salmon was radio tagged at RM 120.7 on 2 September'
(Figure EK-19).Within 32 hours after release the fish was detected
11.6 miles downriver at RM 109.1.About two hours later the same day,
3 September,it was located 1.4 mile upriver at RM 110.5.During 4 and
5 September it was encountered at RM 111.2.However,on 8 September it
moved downstream to RM 107.7 and was observed in Chase Creek (RM 106.9)
at RM 0.3 with two other adult coho salmon.The individual supported
itself on the substrate by it's pectoral and pelvic fins;it appeared
lethargic and did not actively swim away when touched by hand.The
swimming performance of this fish was apparently adversely influenced by
insertion of the radio transmitter.
The fish departed Chase Creek (RM 106.9)sometime before 1100h the
following-day as it was located in the Susitna River at RM 109.0.It-
moved upriver and by 13 September was located at RM 111.3.However,3
days later it was detected at RM 96.8 of the Susitna River,downstream
of the Talkeetna River (RM 97.0),and was consistenly encountered there
thru 7 October.Attempts to retrieve the carcass were unsuccessful.
Coho Salmon,Radio Transmitter #720-3
Coho salmon 720-3 was radio tagged at RM 119.5 on 4 September
(Figure EK-20).Within 21 hours after release this individual migrated
8.6 miles upriver,which represents an upstream migration rate ~0.41
mph.By 8 September it was detected by airplane at RM 131.0,the upstream
migration extent of this individual.Two days later it was detected

downstream at RM 130.4;it continued moving downstream until 17 September
when it was detected at RM 117.8,near Little Portage Creek at the same
milepost.
This fish was consitenEly encountered in the mainstem Susitna River near
the mouth of Little Portage Creek at RM 117.8 from 17 Septe~ber thru
30 September.It was gi1lnetted on 17 September along the east bank of
the mainstem Susitna River at RM 117.9;the fish had not attained spawning
condition,as evidenced by it's silver-pink coloration and non-fluid
character of the gonads.It was detected at or within 0.2 mile of RM 117.9
on 20,23 and 30 September.
The individual was captured alive at RM 117.8 in the outlet of Little
Portage Creek (RM 117.8)on 7 October and necropsied.The necropsy
revealed that the fish had not spawned due to the fullness of the gonads,
although the kype was eroded.
Coho Salmon,Radio Transmitter #730-3
Fish 730-3 was radio tagged at RM 102.9 on 31 August (Figure EK-21).Four
and one half hours after being released it was detected 3.0 miles upstream,
which is comparable to a 0.67 mph upstream migration rate.It was next
detected at RM 111.7 on 4 September,although 3.6 hours later it was
monitored at 2.1 miles downstream.Within 20.3 hours the fish had moved
upstream 12.2 miles;this is equivalent to an upstream migration rate of
0.601 mph.The fish apparently continued migrating upstream,as evidenced
by it being detected at RM 1.9 of Indian River (RM 138.6)on 8 September.
