PREFACE
This report is one of a series of reports prepared for the Alask~Power
Authority (APA)by the Alaska Department of Fish and Game (ADF&G)to
provide information to be used in evaluating the feasibility of the
proposed Susitna Hydroelectric Project.The ADF&G Susitna River Aquatic
Studies Program was initiated in November 1980.
This report covers winter studies (RSA Task 34)conducted from October
15,1984 through May 15,1985 on juvenile salmon and resident fish
species of the Susitna River.In addition,some radio telemetry moni-
toring data is also included for resident fish that were radio tagged in
September and early October 1984.This report has two parts which were
published in separate volumes.
Part 1 presents the results of winter resident fish studies in both the
lower and middle river.Monitoring of selected resident fish movements
through the use of radio tags was continued.Efforts were also made to
describe the overwintering habitat associated with rainbow trout,
burbot,and Arctic grayling,and to identify the timing and locations of
burbot spawning in the lower river.
Part 2 discusses the winter studies of juvenile chinook and coho salmon
that were conducted in the middle river.Findings from this study
define the distribution and relative abundance of fish within specific
overwintering sites,document limited movements of marked fish between
overwintering sites,and present information on fish lengths over the
course of the winter.This report also presents mark-recapture data
which can be used to generate site specific population estimates of
juvenile chinook salmon that overwinter in the middle reach of the
Sus i tna Ri ver.

1.0 INTRODUCTION
The Alaska Department of Fish and Game Susitna Aquatic Studies Program
initiated winter studies of juvenile salmon in November 1980 to gather
baseline data in preparation for proposed hydroelectric development on
the Susitna River.These studies were designed to provide a winter
inventory of the juvenile salmon and to determine factors that were
limiting to their winter survival.
Initial winter studies (1980-81)of juvenile salmon were restricted to
cataloging the distribution of juvenile salmon and their overwintering
habitat (ADF&G 1981c).Later wi nter studies conducted duri ng 1982-83
and 1983-84 were primarily concerned with embryo incubation and fry
emergence (ADF&G 1983f;Vining et al.1985)and surface and intragravel
water temperatures (ADF&G 1983F;Keklak and Quane 1985;and Keklak and
Withrow 1985).
The original purpose of the 1984-85 winter program was to describe the
response of juvenile chinook and coho salmon to changes in mainstem
river discharge as it affected their overwintering habitat,and to
describe their utilization of microhabitat types within their overwin-
tering habitat.
It became evident very early in the winter of 1984-85 that the intended
purpose of the study could not be met because the prevailing river ice
and climatic conditions exceeded the design capabilities of the program.
The study design,therefore,was modified to provide:(1)population
1
estimates of juvenile chinook salmon at selected overwintering sites,
(2)data to detect possible increases in length of fish occupying
selected overwintering habitats,(3)potential movement of fish between
overwintering habitats and,(4)the abundance index of juvenile chinook
and coho salmon (as catch per unit effort;CPUE)in various microhabitat
partitions of the overwintering habitat.
The data from the cold branding/mark-recapture study was designed to be
analyzed using an open population model to generate population estimates
of juvenile chinook salmon at the 1984-85 winter sampling sites.A com-
puter program called POPAN-2 was selected for this purpose.A copy of
this computer program was obtained and implemented on the Boeing
Computer Services TSO (Time Sharing Option)operating system.Due to
funding cuts to the Alaska Department of Fish and Game Susitna Aquatic
Studies Program which were implemented in March 1986,funds for use of
the contract with Boeing Computer Service were "zeroed out"for this
study and the population estimates were not completed.Therefore,the
data which is necessary to generate these population estimates,the
references which are needed to use and understand the computer model,
and the name and phone number of a department biometrician who is
familiar with this data set and can be contacted regarding use of the
POPAN-2 model is provided in this report.

2.1 Study Locations
In mid-October~after water levels had lowered and stabilized,the
following locations in the middle reach of the Susitna River were
selected as winter sampling sites:Slough 9A (RM 133.6),Slough 10 (RM
133.8),Slough 22 (RM 144.3),and Indian River (RM 138.6)(Figure 1).
An important consideration in the selection of winter sampling sites was
that each had to contain sufficient numbers of juvenile chinook salmon
to provide adequate catches throughout the winter.This was necessary
to generate a population estimate of the number of juvenile chinook
salmon at selected overwintering sites in the middle reach of the
Susitna River which may be affected by the proposed hydroelectric
project.
2.2 Field Data Collection and Recording
Mark-recapture studies of juvenile chinook and coho salmon using cold
branding marking techniques were conducted at the winter sampling sites
from October 15,1984 through ~lay 15,1985.
To better descri be the habitat present at juveni 1e chi nook and coho
salmon overwintering sites and to compare the relative abundance of
these juvenile salmon in different microhabitat conditions within
individual sites,each of the four winter study sites were stratified

into "partitions"for sampling.Partitions were defined as sections of
a study site havi ng s imil ar cover types,substrate,water depth,and
flow.Partitions at Slough 9A,Slough 10,and Slough 22 were contiguous
and numbered consecutively from the mouth of the slough to the upper
limit of each of these sampling areas (Figures 2,3,and 4).Indian
River was too large to stratify into contiguous partitions,therefore
one partition was established at each of two sloughs in the lower reach
of Indian River and one slough in the upper reach were juvenile chinook
and coho salmon were found (Figure 5).
Initially the frequency of sampl ing was scheduled to be at 3-5 day
interval s.After three weeks of sampl ing,it was determined that the
sampling effort could be reduced to 10-15 day intervals •
During November,biologists established that winter sampling should be
conducted every 10-15 days.Sampling at intervals of less than 10 days
seemed to produce artificially low catches which were attributed to
overfishing and/or fish avoiding the minnow traps.
~linnow traps baited with salmon eggs were used to capture juvenile
salmon.Five minnow traps were set for about 24 hours in each parti-
tion.Minnow traps were set in the same gene.ral area each trip.All
juvenile chinook and coho salmon that were captured were marked by cold
branding and held overnight for observation prior to release in the
partition where they were collected.

Cold branding procedures similar to those outlined by Mighell (1969)and
Raleigh et al.(1973)were used for marking fish in this study.Each
brand consisted of a single,3 millimeter (mm),brass letter or symbol
that was soldered onto a threaded brass cap.Liquid nitrogen was used
as the cooling agent.
Juvenile chinook and coho salmon were marked with a distinct brand that
signified the day or dates of capture and the location.Fish were
branded at one of six branding locations on their bodies (Figure 6)
using a branding time of 2 seconds.Branding locations were identified
on field data forms by a two-letter code which was recorded in front of
each brand.The first code letter (F,M,or B)indicated whether the
brand was applied on the front,middle,or back of the fish.The second
code letter (Lor R)indicated if the brand was placed on the left or
right side of the fish.The third letter or symbol recorded was the
actual mark that was cold branded on the fish.Therefore a typical
brand on a field data form might be "FRTU,indicating that the fish was
branded on the front section of its right side with the symbol liT".
Recaptured fish were rebranded if they did not already have a brand at
the designated location for the new sampling period.
Date,location,branding symbol,and fishing effort were recorded for
each sampling site.Total number of fish captured by species and total
numbers and symbol s of recaptures were recorded for each partition.In
addition,total length (Tl)measurements of 50 juvenile chinook and 50
coho salmon were recorded once each month at each sampling site in an

attempt to evaluate any tendency for an increase in size during the
ice-covered season.
Data on surface and intragravel water temperatures,percent ice cover,
and ice thickness were scheduled to be collected within each partition
during each sampling period.At the beginning of the study,water
temperatures were measured with a Digi sense thermometer.Because of
frequent malfunctions,use of the Digisense was discontinued early in
the study and a hand-held mercury thermometer was used instead.
Cover and percent cover data were collected from each partition at
winter sampling sites,once in March.A visual assessment of cover type
and percent cover was recorded using criteria defined in Suchanek et al.
(1985)•
2.3 Data Analysis
The catch per unit effort (CPUE)data presented in this report is
calculated as catch per minnow trap day.
Due to problems with the Digisense thermometer and dissatisfaction with
the variability of measurements obtained with the hand-held mercury
thermometer,surface and intragravel water temperature data pod measure-
ments from Keklak and Withrow (1985)were used in the analysis of water
temperatures at Slough 10.
11
Apparent increases in mean size between groups of juvenile chinook
salmon,and between specific sites over time will be proven or disproven
by an analysis of variance.
The 1984-85 cold branding/mark-recapture studies were conducted on open
populations of juvenile chinook and coho salmon at selected over-
wintering sites.Open populations are subject to dilution (recruitment
of new fish into the catchable population by birth,growth,or immi-
gration)and/or losses (by handling,death,or permanent emigration).
The most widely used methods for obtaining population estimates of open
popul ati ons are based on methods that were fi rst proposed by Jolly
(1965)and Seber (1965)and/or their derivatives.For the analysis of
these mark-recapture data,a computer software system written by Arnason
and Baniuk (1978)was selected.This system,called POPAN-2,was
designed for mark-recapture analysis of open populations and it provides
the user with easy access to the full range of variations on the basic
Jolly-Seber analysis and many associated tests (as explained in Arnason
and Baniuk 1978).

3.0 RESULTS
3.1 Biological Data
3.1.1 Chinook Salmon
3.1.1.1 Distribution and relative abundance
Catch per unit effort (CPUE)data given in Figures 7,8,9,and 10
present a general picture of the distribution and relative abundance of
juvenile chinook salmon by partition at each winter sampling site over
the course of the wi nter of 1984-85.CPUE I S were generally highest
between late October 1984 and early January 1985 and then they dropped
off steadily thereafter.At Slough 22 and Slough 9A,catch rates were
higher in the upper partitions,while catch rates at Slough 10 were
generally higher at the mouth.Indian River catch rates were highest at
Len's Slough,the furthest downstream site.
Statistical comparisons of catch per unit effort (CPUE)trends between
partitions at each site was not attempted because the direct use of CPUE
as a measure of population abundance is generally only valid if:1)a
fi shes ca tchabil ity is constant throughout the whole experiment and,
2)if each fish has an equal probability of being caught.The biometric
revi ewer of these data questions the val idi ty of these assumpti ons,

thought to vary during the winter with changes in water temperature,ice
cover,and photoperiod (Bingham 1986).
Catch per unit efforts recorded between November 13 and November 19,
1984 are believed to be artificially low.Sampling during this time was
repeated at 3-to-5-day intervals and it is believed that lower CPUE's
resulted due to overfishing and fish avoiding the minnow traps.For
example,a total of 540 juvenile chinook were captured and released at
Slough 22 on November 11 and 12 respectively.However,on November 15,
only 155 juvenile chinook were captured at Slough 22 using the same
amount of effort.One would expect to catch a similar number of fish
with the same amount of effort,if there are no other factors influenc-
ing the numbers or behavior of the fish.This problem was addressed by
extending the period between sampling trips to 10 to 15 days.
3.1.1.2 Length
In an attempt to evaluate an increase in size of juvenile chinook salmon
over the winter a comparison of juvenile chinook length data by site and
by two-week periods was prepared (Figure 11).Based on this data set,
we cannot verify winter growth in juvenile chinook salmon however we can
detect a tendency for an increase in size within sites and between
specific sites.A visual observation of Figure 11 indicates a slight
difference in the median lengths of juvenile chinook between Indian
River and Slough 22 stocks.The median lengths of juvenile chinook in
Indian River also appear to be larger than their Slough 22 counterparts.
A one-way analysis of variance performed on these data indicated that

the null hypothesis (Ho)should be rejected,therefore there is a
significant difference between the lengths of fish at these two sites
(Table 1).A comparison of juvenile chinook salmon mean total lengths
(TL)with 95%confidence intervals for five time periods at Indian River
and Slough 22 is presented in Figure 12.There is a statistical signif-
icance in the TL's between these two sites during the first four periods
and the TLls of fish in Indian River are larger than the TLls of fish in
Slough 22.In the last period,the confidence intervals of the TL's of
juvenile chinook at Indian and Slough 22 overlap and therefore the
difference of their TL's during the last period is not statistically
significant.
3.1.1.3 Movement
Mark recapture techniques were used to monitor the winter movements of
juvenile chinook salmon between sites.A total of 9,744 juvenile
chinook salmon were marked by cold branding between October 15,1984 and
April 30,1985 (Table 2).Of these,3,265 were later recaptured (Table
3).All but two of the recaptures were made at the same site where the
fish were originally branded and released.One fish was branded and
released in Slough 22 on November 15 and recaptured at the mouth of
Slough 10,10.5 miles downstream on March 30.The other fish was
branded on November 16 in Indian River and recaptured at the mouth of
Slough 10,5.4 miles downstream on February 6.

3.1.1.4 Population estimate data
Population estimates of juvenile chinook salmon at the winter study
sites were not generated due to recent budget cuts.However,a site by
site summary of the mark-recapture data which is needed to produce these
population estimates using the POPAN-2 computer program are presented in
Tables 4 through 9.
Appendix B provides a step-by-step procedure for preparing data from
Tables 4 through 9 for use in the POPAN-2 computer model.
3.1.2 Coho Salmon
3.1.2.1 Distribution and relative abundance
In general,juvenile coho salmon were not found to be widely distributed
or very abundant at the 1984-85 winter study sites in the middle reach
of the Susitna River.Juvenile coho salmon were caught regularly at
Slough 10 and in Indian River,however very few juvenile coho (10
fish)were caught in Slough 9A and Slough 22.Figures 13 and 14 present
the general distribution and relative abundance of juvenile coho salmon
by partition at Slough 10 and Indian River between October 1984 and May
1985.At Slough 10,the largest catch rates occurred in the upper
partitions of the slough (below a beaver dam)on November 9,December 1,
and February 6.The largest catch rates of juvenil e coho sa lmon in
Indian River occurred in 0.0.0.Slough on December 4,January 9,and
January 17.

3.1.2.2 Length
A comparison of juvenile coho salmon length data by site and by two-week
period is presented in Figure 15.These data indicate a general trend
of increase in size of juvenile coho salmon at Indian River over time
which can possibly be attributed to growth or movements of fish into or
out of the sample population.
3.1.2.3 Movement
The winter movements of juvenile coho salmon between sites was monitored
using mark-recapture techniques.A total of 393 juvenile coho salmon
were marked by cold branding between October 15 and April 30 (Table 10).
Thirty of these fish were later recaptured;all but one were recaptured
in the same site where they were branded and released (Table 11).The
one exception was branded and released in Indian River on November 15
and recaptured 4.8 miles downstream in Slough 10 on February 6.The
majority of the recaptures,like the catch,occurred prior to January.
3.1.2.4 Population estimate data
Due to the small number of recaptures,no population estimate were
attempted for juvenile coho salmon.

3.2 Habitat Data
Slough habitat and morphology for the open-water season have been
recorded for each of the study sites in previ ous ADF&G reports (ADF&G
1981a,1983c;Marshall 1983;Estes and Vincent-Lang 1984).
Discharge in the middle Susitna River averaged 2,100 cubic feet per
second (cfs)during the winter study,ranging from a high of 5,600 in
October to a low of 1,600 in April (Figure 16).
Table 12 presents the cover characteristics which were observed at the
study sites during March 1985.Cover ranged from none to boulders and
included debris and aquatic vegetation.
Figures 17, 18,19,and 20 show the percent ice cover present at the
four winter study sites by partition.Ice cover was a highly variable
habitat characteristic during the winter study at most of the par-
titions.Partitions with higher velocities had less ice cover,deeper
partitions had more ice cover,and rising and lowering air temperatures
decreased and increased ice cover,respectively.
Figure 21 shows the average of the mean air temperatures as recorded at
the Sherman Weather Station at RM 129.2 (R&M Consultants 1985)and
compares it with the surface water temperatures measured at Partition IV
in Slough 10.Surface water temperatures for this partition seem to
follow the same general trend as the mean air temperatures observed at
these times.

4.0 DISCUSSION
4.1 Chinook Salmon
Adult chinook salmon returning to the middle reach of the Susitna River
are not known to spawn in the turbid mainstem.Spawning takes place in
clear-water tributaries to the mainstem river during July and August.
Emergence of fry takes pl ace the foll owi ng Apri 1.Juvenil e chi nook
salmon rear in fresh water for up to two years.Scale analysis of adult
chinook return"ing to the middle reach of the Susitna River indicates
that the majority (98.5%over the past four years)of chinook juveniles
were age 1+juveniles which had reared one year in fresh water.
Juveniles rearing in fresh water for two years (age 2+)have never been
documented in the Susitna River drainage and it is theorized (Roth &
Stratton 1985)the three remaining 1.5%of chinook juveniles migrated to
sea in their first year (as age 0+)of fresh water life and may
experience high mortality.
Chinook salmon juveniles in the middle reach appear to be separated into
two behavioral groups:(1)those that spend a portion of their first
summer in the mi ddl e reach,then mi grate out of thi s reach before
winter;and (2)those which spend their entire first year within the
middle reach.The first group was reported in Roth and Stratton (1985),
whil e the second group is the subject of thi s report.The rel ative
contribution of these two groups with respect to returning adult salmon
is not known at this time.
41
"------------~---------------------------
Within the second group are two sub-groups:(a)those which remain an
entire year within their natal tributaries before beginning their
smolting migration,and (b)those which leave their natal tributaries
and overwinter in slough and side channel habitats in the middle reach.
Previous winter studies (ADF&G 1981c,1983a,1983b)and data from this
study indicated that little overwintering other than migrational move-
ments occurs in the mainstem Susitna River.
From late October through mid-January there appears to be a redistribu-
tion of juvenile chinook in Indian River from the upper sites to the
lower sites (Figure 9).By the middle of January,catch rates at all
three Indian River sites had decreased to 1.5 -3.0 fish per trap day
and remained at or below this level for the rest of the ice-covered
season.During this same period,catches in the two sloughs downstream
from Indian River increased (Figures 7 and 8).These data,combined
with the fact that one juvenile chinook and one juvenile coho branded in
November in Indian River were recaptured in January and February in
Slough 10,suggest that some juvenile chinook may have migrated out of
Indian River between mid-December and mid-January.Catches at all
winter sampling sites dropped dramatically after mid-January,suggesting
that this outmigration of juveniles was not confined to Indian River,
but occurred throughout the middle river.The recapture of a fish
(branded in November at Slough 22)at Slough 10 in March also lends
support to this hypothesis.
The reason or reasons for this movement out of Indian are not known at
this time but several possible reasons are suggested by graphically

.....
comparing juvenile CPUE and percent ice cover.Although these data are
speculative,when percent ice cover and air temperature are compared to
the catch rates at most sites (Figure 22),the catch seems to correspond
with the increases and decreases of these two pa rameters duri ng the
first half of the season.This is most evident in Indian River where
water temperatures reach the freezi ng poi nt by early November.Duri ng
the period when the juvenile movement was thought to have occurred in
the Upper Indian River,air temperatures had just risen from their first
extreme low of the season (-10 to -24°C in late November and early
December),the most extensive ice cover to date was in place.When air
temperatures approached the second extreme low of the season in late
December,the extent of ice cover remained high and the juveniles were
thought to have been in the process of leaving the lower areas of Indian
River.The temperatures then rose and were warmer until mid February,
after which the coldest weather of the season occurred and virtually all
of the sites were ice covered.During the warming period in January,we
had expected that catches at all sites would increase due to increased
activity by the fish,but this was not the case.Catches at mainstem
slough sites increased,but catches at Indian River continued to fall.
This could be the result of:(1)a large number of fish moving into the
mainstem slough sampling sites.(2)a large number of branded fish
moving out of the Indian River sampling sites,or (3)a high winter
mortality of juvenile chinook salmon at the Indian River sites •
A similar trend is believed to have taken place within the mainstem
slough sites over the course of the winter.In September.large numbers
of juveniles were visually observed at the mouths of mainstem sloughs.

By mid-October the juveniles seemed to have slowly dispersed within the
sloughs with the major concentrations in areas having more cover and
groundwater sources (Roth and Stratton 1985).
In early May,as the days became longer,water and air temperatures
increased,ice cover receded,and fish became more active.One might
expect that catches would increase with improved conditions,especially
at partitions in the lower sections of the sites.As can be seen in
Figures 7,8,9,and 10,this did not occur.Either the majority of
juvenile chinook had left the sites prior to this time or the winter
mortality among juvenile chinook salmon was very high.
4.2 Coho Salmon
Adult coho salmon spawning in the middle Susitna River has been docu-
mented almost exclusively in tributary streams.Very small numbers of
coho salmon have also been observed spawning in sloughs and at mainstem
sites used by other species of salmon.Spawning occurs from August to
October and the alevins emerge in March and April.Coho salmon juve-
niles remain in freshwater for up to three years,but scale analysis of
returning adults indicates that approximately one-half of the returning
adults were age 1+juveniles and the other half age 2+(ADF&G 1981b,
1983d,1983e;Barrett et al.1984,1985).A total of 472 juvenile coho
salmon were captured during the 1984-85 winter studies.Of these,only
18 were age 2+,indicating that the majority of the 2+fish overwinter
in habitats below the middle reach.
45
f ....
Few juvenil e coho were captured compared to chi nook (472 coho versus
11,543 chinook).In general,coho salmon juveniles were found to
exhibit similar movements and responses to mainstem changes as chinook
salmon juveniles.
Since so few juvenile coho salmon were captured and subsequently recap-
tured,no population estimates were calculated.
4.3 Habitat Data
Before freeze-up (prior to mid-October)mainstem discharges were crit-
ical for passage of juvenile chinook and coho into the mouths of certain
sloughs (e.g.,Slough 22).Juvenile chinook and coho salmon that
outmigrate from tributaries (e.g.,Portage Creek)into the mainstem
between mid-August and late September have greater access to sloughs for
winter rearing during higher discharges (>4,000 cfs).
During freeze-up (mid-October through November)winter rearing areas in
sloughs and side channels are affected by ice jams which back up
mainstem water and result in localized flooding and the formation of
overflow ice.Breaching of sloughs and side channels with cold mainstem
water duri ng freeze-up can fl ush out fry whi ch have sought out the
warmer ground waters in these areas for overwintering.The formation of
overflow ice also reduces the area within a site which is suitable as
overw"j nter-i ng habitat.For exampl e,at Slough 22,overflow events
during November covered the lower 400 feet of the slough with ice that
was 20 inches thick.

After freeze-up (December through mi d-May)rnai nstem di scharges in the
middle Susitna River were basically stable for the remainder of the
winter.During February,staging was observed at Slough 10 after a
heavy snowfall.The additional weight of the new snow on the surface
ice in this area backed up mainstem water over 2,000 feet into Slough
10,increasing the average water depth at most sampl ing partitions by
about two feet and decreasing the surface water temperature in the
slough by about 0.5°C.Although this event increased the wetted area
that was available to juvenile salmon in Slough la,no large influx of
fish was observed.
The only major difference observed between chinook and coho juveniles
duri ng these winter studi es was habi tat preference.Cohos preferred
areas with greater depth and cover consisting of debris,vegetation,and
undercut banks,whereas chinooks preferred shallower,slightly higher
velocity and cover consisting of rocks and boulders.Beaver dams and
ponds were found to be excellent coho habitat.(Partition V of Slough
10 and Beaver Pond and 000 Slough in Indian River are prime examples.)
This corresponds with the findings of Suchanek et ale (1984)for summer
coho habitat preference.

Grouping Sampling Periods
For this analysis,it was necessary to group sampling periods (days)
with the same brands.These groups have been called "occasions"and
they may represent from one to three sampl ing days when a particular
brand was used or the last sampling day or sampling days when branded
fish were recaptured at a particular site.Appendix Table B-1 defines
the occasions at each 1984-85 winter sampling site by sampling dates
when branded fish were released or recaptured.
Creating Record Files
A program entitled CTAGREC.PLI (Appendix Table B-2)was used to create
the initial tag records for juvenile chinook salmon that were branded at
Slough 9A using the information provided in Table 4.An example of how
CTAGREC.PLI interacts with the computer operator us i ng the Slough 9A
data is given in Appendix Table B-3 and a sample printout of a partial
record file for Slough 9A is shown "in Appendix Table B-4.A diskette
containing the CTAGREC.PLI program will be transmitted to Harza-Ebasco
Susitna Joint Venture with this report.Tag record files for Slough 10,
Lenis Slough,0.0.0.Slough,Beaver Pond Slough,and Slough 22 can be
generated using the CTAGREC.PlI program and the data presented in Tables
5 through 9.

Creating History Files
After the initial tag record files have been created,the histories of
each tagged fish needs to be completed.The recapture histories for all
tagged fish by sampling location and occasion are presented in Appendix
Tables B-5 through B-lO.An explanation of how these history tables
should be interpreted is presented using Appendix Table B-5 as an
example.The first column indicates the occasion.The headers in
columns two through nine give the branding location code,the cold
branding symbol that was used,and the occasion that each was deployed.
Column ten presents the number of fish which were recaptured by occasion
and each number corresponds with a particular brand or brands that are
indicated on the same line by one or more XiS.The last column refers
back to the tag numbers that were assigned to each fish in column one of
Appendix Table B-4 and it presents the range of tag numbers that make up
this category.The last column in Appendix Table B-5 is provided only
to help the reader understand how this table was derived and it is not
used in the POPAN-2 analysis.Therefore,in occasion 4 of Slough 9A,3
fish were recaptured that had an FR -brand which had been deployed in
occasion 1;2 fish were recaptured that had FR and FL -brands which
had been deployed in occasion 1 and 2 respectively,etc.In addition to
requiring information on recaptures of tagged fish,the POPAN-2 model
also needs information on mortalities of tagged fish.There were no
known mortalities of tagged juvenile chinook salmon at Slough 10 or at
Len's Slough,0.0.0.Slough,or Beaver Pond Slough on Indian River.
Mortalities of tagged fish at Slough 9A and Slough 22 are presented in
Appendix Table 8-11 and 8-12.

The recapture and mortality histories for each site are then used to
update the occasions that individual fish were captured and the number
of times each fish was captured in their original tag record file.An
example of the updated record file for Slough 9A is presented in Appen-~
dix Table B-13 and a brief explanation of how these updates were made is
presented below.This record file indicates that there were 265 juve-
nile chinook salmon that were captured,branded,and released during
occasion 1 at Slough 9A.Information from Appendix Table 8-5 indicates
that fourteen of these occasi on-I-branded fi sh were recaptured duri ng --
occasion 2;22 of the occasion-I-branded fish were recaptured during
occasion 3;and 3 of the occasion-I-branded fish were recaptured during
occas ion 4,etc.Of the fi rst fourteen fi sh whi ch were captured in -occasions I and 2,two were subsequently recaptured in occasion 4,two
were recaptured in occasion 5,and two were also recaptured in occasion
6.Each of these first six fish were captured a total of three times,
therefore the updated record file should indicate each occasion when
these fi sh were captured and the total number of times that each of
these fish were captured.Appendix Table 8-11 shows that five of the
-
--
twenty-two occasion-I-branded fish,which were recaptured in occasion 3,-
di ed.Therefore,a mi nus sign (-)was added as a prefi x to the 1ast
five fish in this group to indicate that these fish had died.Similar
procedures were used to update the remainder of the record fi 1e for
Slough 9A.A copy of the updated record fil e for Slough 9A entit1 ed
SL9A041.POP will be contained on the diskette that is transmitted to
Harza-Ebasco Susitna Joint Venture with this report.

Persons interested in generating population estimates for Slough 10,
Len's Slough,0.0.0.Slough,Beaver Pond Slough,and Slough 22 will have-
to create and update the history files for these sites using the same
procedures indicated for Slough 9A.After all of these history files
have been updated,they can be used in the POPAN-2 computer model to
generate population estimates of juvenile chinook salmon at the 1984-85
winter sampling sites.
Generating Population Estimates
Due to funding cuts,population estimates of juvenile chinook salmon at
the 1984-85 winter sampling sites were not completed.Therefore,anyone
wishing to generate population estimates from this data set will have to
complete the analysis him/herself using the POPAN-2 computer model which
is discussed in Arnason and Baniuk (1978).
An individual who can be contacted regarding use of the POPAN-2 model
is:
Allen Bingham

Mr.Bingham secured a copy of this computer program for this analysis
and has implemented the program on the Boeing Computer Services TSO
operating system.

FIELD OBSERVATIONS ON PREDATION
AND FOOD AVAILABILITY

Predation on Juvenile Chinook and Coho Salmon at Winter Sampling Sites
Winter predation on juvenile salmon was observed frequently during the
1984-85 winter studies.As winter ice formation progresses,the amount
of area available to the juvenile salmon shrinks,thereby concentrating
the fi sh and maki ng them more suscepti b1e to predators.A1though ice
and snow cover do replace turbidity as a source of cover from ter-
restrial predators,juvenile fish are still vulnerable to these
predators through open 1eads.The most acti ve and successful terres-
trial predator observed during this study was a bird called a dipper
(Cinclus mexicanus).Dippers were observed throughout the winter at
almost all open-water areas of the Susitna River.Concentrations of
dippers were observed at partitions containing large numbers of fish and
were frequently observed capturing juvenile fish.
A species of shrew was also found to prey upon juvenile salmon.On at
least three occasions,shrews were found in minnow traps which had been
set with a portion above the water surface.The only remaoins of the
fi sh were pi eces of heads and tail s.Although no shrew predati on on
juvenile salmon outside of minnow traps was observed,it is believed to
occu r.
Other terrestrial predators known to prey upon fish also occur within
this area,including mink,marten,and otter.However,no evidence of
juvenile salmon predation was documented for these species.

The most abundant and probably the most successful predator of juvenile
salmon that we observed is the slimy sculpin (Cottus cognatus).Slimy
sculpin are found throughout the Susitna River~with highest
concentrations occurring in the sloughs and tributaries containing high
numbers of fi sh (ADF&G 1981c).Scul pin were captured inci dentally at
all sampling sites throughout the winter.Sculpin were also observed,
both in minnow traps and lyi ng on the substrate,dead wi th j uvenil e
salmon protruding from their mouths.The fish had apparently choked or
strangled on a juvenile salmon that was too large for it to swallow.
Sculpin predation could be an important factor in winter survival of
juvenile salmon~especially the smaller fish.
Other resident fish species are present in the middle reach of the
Susitna River,but few have been documented in the sloughs and tribu-
taries during the winter (Sundet and Wenger 1984;Sundet and Pechek
1985).Although these fi sh do not.appear to be a threat to juvenil e
salmon in the shallower sloughs and side channels,species such as
burbot and rainbow trout could present a threat to outmigrating juve-
niles in the mainstem.
Food Availability for Juvenile Chinook and Coho Salmon at Winter
Sampling Sites
With the exception of Partition IV at Slough 22~food was available at
all sites throughout the winter.At DOD Slough in Indian River~the
rocks were literally covered with larval and pupal stages of aquatic

insects.(Partition IV shrank to a single pool approximately 20 feet in
diameter,completely cut off from the rest of the slough.)Fish
stomachs examined occasionally throughout the season were ~lways found
to contain insects.From mid-April on,large hatches of aquatic insects
were present at all sites and still little increase in lengths were
recorded.
