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 Manual, Subtask 7 .10, Fish _Ecology Impact Assessment and August 1981). The tas~·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 Terrestrial Environmental Specialists (TES). E-2-1 3.0 OBJECTIVES The data contained in this draft Anadromous Adult project species/subject report was collected by the Alaska DepartmGnt of Fish and Game to meet the specific objective and tasks outlined in the ADF&G Aquatic Studies Procedure Manual for Phase I in 1981 as follows: Objective 1. Task 1.1 Task 1.2 Task 1.3 Determine the seasonal distribution and relative abundance of adult anadromous fish populations produced within the study area. Enumerate and characterize the runs of the adult anadromous fish. Determine the timing and nature of migration, milling and spawning activities. Identify spa\vning locations within the study area (i.e., subreaches of the mainstem sloughs and side channels, tributary confluences, lakes and ponds,_ etc.) and estimate their comparative E-3-1 4. t·1ETHODS 4.1 Mainstem Investigations Five escapement monitoring stations were established in early June 1981 at the locations identified in Figure E.4.1. Individual site description maps are provided in Figures EA-1 through EA-5. The operating dates and gear deployed at these sites were as listed in Table E.4.1. The Yentna, Sunshine, Talkeetna and Curry stations were operated under the direction of Su Hydro, Adult Anadromous Investigations personnel. Susitna Station was run by Alaska Department of Fish and Game, Commercial Fisheries Division staff. Table E.4.1.

Figure E.4.1. Susitna Basin with field stations and major glacial streams defined, Adult Anadromous Investigations, Su Hydro Studies, 1981. The side scan sonar (SSS) 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 C1980). A brief narrative of how a sonar works is provided in the following ~aragraph. 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 the' 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 . .

The fishwheels used at each project location were of identical design with two baskets and two paddles (figure E.4.4}. 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 (m} 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 em 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 em steps to a minimum and maximum height of 30.5 and 122 cm,·respectively, above the top of the floats. A 122 em long, 76.2 em wide and 122 em 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. E -4 -6 Figure E.4.4. Fishwheel operating off west bank Susitna River at Curry Station, Adult Anadromous Investigation, Su Hydro Studies, 1981. Each weir was built to conform to the river bottom at the location of installation and extended from the shore perpendicular to the downstream end of the livebox. Weirs were not used at Sunshine Station because of debris problems. All fishwheels were adjusted daily to insure that the baskets fished within 15.2 ern 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 fishwheels were scheduled 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 constraints3 continuous operation was not always possible. Sampling checks were usually made four times daily at each fishwheel. Forty sockeye, 25 chum, and 25 coho salmon were sampled daily for age, length, and sex from fishwheel catches at sampling station. Age samples were obtained by removing the 11 preferred 11 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 (mm). 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, Talkeetna and Curry stations were tagged. An e~ception 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 through 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. Table E.4.2.

Orange Station E - 4 - 9 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 Gold Creek Station Survey Crew Estuary to Kashwitna River (RM 0 to RM 61) Kashwitna River (RM 61 to RM 108) to Chase Chase to Devil (RM 108 to RM 151) . ·.. , · · ·· Canyon· The crews used a combination of drift gill nets, electroshockers, 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 5. Presence of debris 2. Relative water velocity 6. Presence of spawned 3. Water turbidity out fish or fish surfacing. 4. Water depth E - 4 - 1 0 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 spawning areas were identified and sampled. Drift gill nets used in sampling the mainstem were 15.2 m long, 1.5 m deep, 13.3 em 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 d~bris along w-it.h fluctuating depths generally 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 expells eggs or milt when slight pressure is exerted on the abdomen. E -4 -1 1 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~l510B 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 refi-ned dimension in reso.lution-and deta.il 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 l·owered 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 generally .. 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 CTable 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 em stretched mesh E - 4 - 1 nylon gill net in eddies in the mainstem between Devil 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 Susitna 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 att'ached 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 em. Samplino with this gear was E - 4 - 1 4 ~~Figure E.4.5.

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 em in diameter. They were fitted with a 13.0 em 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 - 1 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 fishwheels. Each fish was transferred by net from the fishwheel 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 11 • Fish with fresh wounds or those fitting the definition of "stressed 11 were classified as unsuitable fo~ tag·gi ng .-, stFessed:' fi sn w~re ·'gently reinoved from· the' tank and held. in shallow, slow moving water by hand until they revived and forcefully swam away. Three fish were found to be suitable for experimental tagging and preparations were made to implant the radio transmitter. Tricaine methanesulfonate (M$~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 - 1 7 hook first into a 1.95 em diameter,. 50.2 em long plexiglass tube which served as an insertion instrument. A wider, 2.5 em diameter, 32.4 em 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° 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 positforr. · Ttie ·fish· was-transferred to the adjacent compartment of the tank containing fresh water and revived. The first experimentally implanted transmitter was positioned in the posterior of the stomach [Figure E.4.7(A)]. 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 em 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.4.7(B,..C)]. 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. E - 4 - 1 8 Figure E.4.6.

E - 4 - 2 0 From these results the decision was made to implant the transmitter in the anterior portion of the stomach cavity in chum salmon Ifigure E.4.7(D}]. This location was determined to be when the anterior (antenna} end of the transmitter just disappeared from sight behind the esophagial sphincter. Hhen 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 em of the antenna. Following transmitter implantation a h01'1ow·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. F. -.1 -? ...... 1 During live radio transmitter implants the procedures outlined above for fish capture and selection were used. Prior to insertion however, the tag was checked a final time while submerged in a container of water and tested for signal strength and frequency of transmission. The heat~to~ shrink material was installed on the antenna wire and 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 em 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 . a'gainsfthe blank disc. The-~easDring, ~eighing 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 muscular 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 M$~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 cm3 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 pa~ks:··.·-rh~ r~ceive.rs and ba'ttery 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 tagged 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. Monitoring of tagged fish vJas conducted by air at one to four day intervals 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.

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 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 . ·,. :· , .. ·. ~ , . ' : ·; . . . .

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 = R X 100%. 1 + t ·ThE: percentage \vas· then multiplied 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 reader 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.

Fishwheel catches are summarized in Table E.5.2. Daily sonar counts and fishwheel catches by sampling station are provided in Tables EB-1 through EB-8 and ED-1 through 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 coun~ed 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. Fishwheels 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 E - 5 - 1 m 01 (\) ~ -. ,,.

Ninety~two percentmigrated 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.5.2). Seventy-five percent of the fish passed in a 12 day period between 12 July and 23 July. A total of 7,000 sockeye were caught in fishwheels at Yentna Station. Fishwheel catches indicate that the peak of migration occurred between 13 July and 15 July with the majority of fishwheel interceptions (70.0%) on the south bank (Figure 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.

Based on 'fishwheel ~atch records-(TabTe ED.:.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~2l it qppears that the peak of migr~tion occurred between 27 July and 1 August w-ith sockeye showing no apr:>arent bank preference. Curry Station fishwheels intercel'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 o.f 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 ~nd p.ink salmo~· usually migrate near''shore withi~· 6o 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}.

At Talkeetna Station~ 4.9 percent and 2.2 percent were recorded in the saJTie 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. Sockeye 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 along with the components used to calculate them are presented in Table E.5.3. ThesepopuTation estimates, as with others which w-ill 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 mainstem well upstream of their spawning d~stination (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. al., 19751. Tag induced mortalities were not considered significant due to minimal amount of time (10-20 E - 5 - 1 0 Table E.5.3.

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 tagging 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 . per~ent). based on survey crews. not finding any. shed Petersen disc tags during spawning ground surveys and the general difficulty encountered in removing these tags from carcasses.

It should not be assumed that all fish pass over the SSS substrate. As previously discussed, the sector distribution of sa.lmon 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 irr 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 vart~nc& 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 mortality 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 loss, 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 population 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 mi9rational 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 Talkeetna Station had an average travel time of 8 days and T3days res.pectively (FigureE.5.5). Thfs 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 E - 5 - 1 4 m 1-z w 0 0: w a. w ;:: 1- 80 60 :s 40 ::J ::::!: ::J 0 20 (A) 6/20 _,.-·-· ,.'' .-' ~' I ,• I l . .

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 di.splay 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 · · inore than 26' ·days ear·l i er at Sunshine· Stati an 1 ocated 23 mi 1 es 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 bath 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 E - 5 - 1 6 :-~. :-...s 100 -100 ~~ 25 25 -. 20 >-0 z w :::> 0 15 w a: u.. -SOCKEYE Rltnge. 3 -44 .. n • 24 20 >-(.) z ·.~ 15 w [f -PINK Range 2 • 3Q n•8 - 1-z w 10 0 a: llJ Q.. . ffi 10 0 :· ~ .... r- - 5 5 -u I 0 10 20 30 40 45 0 10 20 30 40 (A) NUMBER OF DAYS BETWEEN CAPTURES (B) NUMBER OF DAYS BETWEEN CAPTURES 100 ----. 100-r----------------------------------·----------~ -p II I 20->-0 z w :::> 0 15-w a: u.. >- CHUM I ·0 15~ COHO z Range 2-9 w Range 5 -4.1 :::> n .. 9 0 n. 31 w [f 20 1-II r' ...., ,---z w 10-0 a: w Q.. 1-z 10 lU (.) \ a: lU Q.. 5-5 0 10 20 30 .. 40 0 10 20 30 40 (C) NUMBER OF DAYS BETWEEN CAPTURES (D) NUMBER OF DAYS BETWEEN CAPTURES Figure E.5.6.

The migrational preference displayed by sockeye salmon for a particul~r 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 bet\'Jeen 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 s2 (Table E.5.5). The next abundant were age 42 sockeye followed by age 62 sockeye. Five year old sockeye, 1976 brood year, comprised apprqximately 86 percent of the return at Susitna and Yentna stations, 73 percent 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 E - 5 - 1 9 m 01 1\) 0 11 10 9 8 1-z w 0 7 cr: w 0.. 6 5 2 0 \ \ 0 \ '\ O··---~ II \ \O·.. \ ~ . .

Table E.5.6 provides a summary of the sockeye salmon length data collected at each of the sampling stations. Graphic representation of this information is provided in Figures EF-1 through EF-5 and Figures EF-21 through EF- 23. Five year old male sockeye salmon averaged 590mm, 605mm, 604mm, 57lmm, 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, 55lmm and 560mm. The combined sockeye salmon lengths of all ages ranged from 230mm to 675mm at Susitna Station, 310mm to 684mm at Yentna Station, 395mm to 635mm at Talkeetna Station and 335mm to 640mm at Curry Station. Male sockeye salmon were larger than females in all age classes (Tabl.e 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 .6 to 1.0).

The migration essentially began on 23 July, peaked on l 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 fishwheels intercepting 91.3 percent and the west bank fishwheels catching the remaining 8.7 percent. Figure ED ... 5, a plot of fishwheel 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 fishwheels operating at Talkeetna Station intercepted a total of 379 pink salmon. Fifty-nine point four percent were caught by the east bank fishwheels and 40.6 were caught by the west bank fishwheels. Figure ED-5 graphically illustrates that peak fishwheel 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 f.ishwheel catch (69.9 percentl at Curry Station was made on the east side of the river. Population estimates. derived from tag and recapture data indicate that 48,459 pink salmon were present at Sunshine Station, 2,574 present 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 mi 1 es per day. These trave 1 rates are· va 1 i d 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. E -5 - 2 7 Table E.5.7 provides a summary of the pink salmon length data collected at ea·ch of the mainstem sampling stations. Graphic representation of this data is provided in Figures EF~6 through EF~lO and Figure EF~24 . . The average length .. af male pink salmon at Susitna Station was: 444mm, 478mm at Yentna Station, 445mm at Sunshine and 4321nrn at Curry Station. In comparison females averaged 433mm, 47lmm, 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 an: sampling stations except at Talkeetna Station where females were 20 percent more numerous (1:1.2) than males. Chum Salmon A total of 46,461 chum salmon were enumerated· at Susitna Station with SSS counters. The majority (91.1%) of the fish were enumerated along the east side of the river and the balance (8.9%) along the west bank counter. The migration arrived at Susitna Station, on 10 July, reached a mid-point on 27 July and passed on 25 August (Figure E.5.10). Seventy five percent of the escapement was counted between 15 July and 6 August. A total of 250 chum salmon were caught in the fishwheels operated at Susitna Station.

The Yentna Station SSS counters enumerated 19,765 chum salmon. SiAty~ 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.5.10l. 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 ~almon 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 east 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 fishwheels 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 fishwheels 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 E - 5 - 3 1 were enumerated on the· east bank SSS. The migration approximately begqn on 28 July, reached a mid~point on 8 August and ended on 29 August (figure E.5.10l. 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 salmon were intercepted by the fishwheels at Talkeetna Station. Seventy~ five percent were caught between 4 August and 7 September with 48.7 percent and 51.3 percent of the total catch intercepted on the east and west bank respectively (Figure ED~8l. Fishwheel 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-9). The majority (89.6%) of the catch made on the east side of the river. Tag and recapture data indicates that 256,667 chum saimon were present at Sunshine Station, 20,244 at Talkeet~a Station and 12 3 934 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.

Percent daily sonar counts of churn salmon by two hour blocks at Sunshine Station, Adult Anadrornous Inv~stigations, Su Hydro Studies, 1981. Chum salmon tagged at Sunshine-Station took between t~ro and nine days to reach Talkeetna Station (figure E,5.6l. Between Talkeetna Station Md 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.5.7l. 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. 11}. 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 ~ther stations due to the absence of discrete periods when chum salmon comprised 90 Rercen.t 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 comprising an average of 86 percent of the fish. Next abundant were age s1 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 s1 and 31 fish respectively. This is a considerable variation from the above cited averages for the combined stations. -.... 5 ... - 3 3 .' Table E.5.8.

Chum salmon of all age classes at Susitna Station ranged in size from 445mm to 658mm, at Yentna Station from 436mm to 697mm, at Sunshine Station from 455mm to 718mm, at Talkeetna Station from 480mm to 720mm and at Curry Station from 440mm to 680mm. Four year old male chum salmon had an average length of 593mm, 60lmm, 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 58lmm, 585mm, 588mm, 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 Susitna Station. Seventy percent were registered by the east bank SSS and the balance by the west bank SSS. The migration began, reached a mid-point and ended on 20 July, 28 July and 25 August respectively (figure E.5.12).

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 fishwheels 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 ~nd 25 August (Figure ED"ll}, The SSS counters at Talkeetna Station recorded a total of 3,522 coho ":<.: salmon.

Seventy five percent of the coho salmon were counted in 22 days from 11 August 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.

This represents a travel rate of 3.9 and 3.2 miles/day respectively. These migration rates are based on the' assumption 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 trave 1 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.

Eight of the radio tagged chum salmon moved upstream from th~ir respective tagging locations. Two others moved downstream and one remained within +0.2 river miles of its tagging location (Figure E.5.21 .) 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 Si;ilmon bearing transmitters numbered 650-3, 680-2 and 710-2 (Figure E.5.21l. Indirect movement was displayed E - 5 - 5 9 ',, -Table E.5.14.

The five remaining radio. tagged chum salmon exhibited other movements (Figure E.5.21). 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 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'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 11 Cz l. speeds. E - 5 - 6 3 The fastest documented rate of chum salmon migration was 1,0 miles per hour Cmphl (Jable E.5.15l. Fish bearing transmitter number 710 ... 2 moved 1.9 miles U!'Stream within 1.9 hours after release. Perhaps more typical of sustained rapid movement is the subsequent 11Jovement 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 ~ 0.13 mph or 3.1 miles/day. Rates of movement of two radio tagged chum salmon which migrated 11 directly" 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 ~prtver of Curry Station 48 hours after being radio tagged at Talkeetna Station. ~. •.

One hundred six chum salmon tagged with Flay ta~s at Talkeetna Station were recaptured by fishwheels at Curry Station 16.5 river miles upriver. Twenty of the 106 fish were recaptured after one day of 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 E - 5 - 6 4 Table E.5.15.

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 131.0}. 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 98.6). Fish bearing transmitter 730=2 was last detected at RM 127.0 Radio tagged chum salmon entered spawning areas between 8 August and 23 August. Fish bearing transmitter number 710-2 entered Slough 11. (RM 135.5) about 13 August and was observed building a redd on 21 August. It had completed spawn.ing by 2 September when it was captured and necropsied. Fish bearing transmitter number 740-1 entered Moose Slough (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.

A necropsy indic~ted the fish had spawned, ~s evidenced by the l~ck of eggs in the coelom. Individual movements 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.5.16). Eight bore wire reinforced radio transmitters where~s two carried non-reinforced transmitters (660-2 and 680 .. 1).

Fish bearing transmitter number 650-1 moved downstream and remained in the Talkeetna River (RM ~7.0) 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-l 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 0 Little Portage Creek, through early October and apparently did not spawn. Movements of coho salmon apparently were not influenced by fiow conditions ·-w-fthin the Susttna River· (Figure E. 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 relatively long periods of time separating some successive fish positions probably under-estimated the upstream migratton rates (Table E.5.17}. 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 equal to or exceeding ( ~ ), except. for those successive fish positions :·separated by less .·than-five·'-hours·~.,--: .. · .. c_o:' .... ' • .. • Behavior o.f adult radio tagged coho salmon near the mouths of Susitna River tributaries was variable (Figure E.5.22). Some individuals, such as fish bearing transmitter numbers 650-1 and 660-2, occupied positions in the mainstem Susltna 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 CRM 131.0} and Little Portage Creek (_RM 117.8}, 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 E - 5 - 7 1 Table E.5.17.

Susitna River tributaries in September. A female fish beat~ing 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 CRM 131.0). on 20 September, On 23 E - 5 - 7 3 Septem.ber it was .detected in the Susitna River at RM 130.0. The sp~wning status of this fish was not determined. Individual movements ~f radio tagged coho salmon are further described tn Appendi-x EK. Other telemetry studies have detected radio transmitter regurgitation among adult coho salmon and steelhead trout~ salmo qairdneri. Two of twenty three aqult 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 esophageally implanted with the .·.: .:. :-:·,::·~ ··::·· <.,· .. · ... : •. .-... ~"'.· .::;.~~·;;;::' ~ _ ... ·-.:: -.~ ~.~: .... · .. · .. : ... · .

Three adult steelhead trout in the Clearwater River, Idaho also were presumed to have regurgitated transmitters, measuring 9.7 em 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.

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 Indian River confluence (RM 139.6). Sometime during the following three days the fish entered the Indian River (RM 138.6) where it was found 1. 3 miles above the confluence on 13 August. It remain e.,.. in the Ir:.d · an River between RM 2.1 and 0.6 for the remainder of the season, fifteen tracking flights.

During the next eight hours the fish~._moved downstream about 0.8 mile. Within 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.

This fish was apparently captured by a predator. This female chum salmon was radio tagged on 12 August at RM 119.5 (Figure EK-3). It displayed very little movement following release. Within 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 RM 119.8, a position only 0.3 miles upstream from its release site. During 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. : -~. .. -.· ..• l.~. : ·. · ... :·. '.·. . :· ... -. · .. :::.

On 23 August it moved to the east side of the river near the confluence with Sherman Creek (RM 130.8). On 24 August it was observed in Sherman Creek, approximately 55 yards upstream of the confluence with the Susitna River (RM 130.8). Between 26 August and 30 August it returned to the west shore of the Susitna River at 130.8. On 3 September the transmitter signal became weak.

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 ll. 6 !niles ·.downri"Ver "at ,RM 109 .l. 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 downstrQam to RM 107.7 and wns observed in Chase Creek (RM 106.9) at RM o. 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 perfo~~ce of this fish was apparently adversely influenced by insertion of the radio transmitter. The fish departed Chase Creek (RM 106.9) sometime before llOOh the . foilcSw:frig-'-day a~ it was. io~ated in the· Su~itn'a 'Riv~r· at RM 109.0. rr·-- 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. O) ·, 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.

This fish was consitently encountered in the mainstem Susitna River near the mouth of Little Portage Creek at RM 117.8 from 17 Sept~~er thru 30 September. It was gillnetted 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 t.o 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.
