ABSTRACT<br />

The 2006 Shell <strong>Lake</strong> adult escapement was the first time since 1986 that CIAA monitored Shell<br />

Creek by use of weir. The adult escapement was enumerated from 15 July and continued daily<br />

until 19 August when the weir became inoperable due to extreme flooding conditions. During<br />

this time 69,800 adult sockeye (O. nerka) salmon returned to Shell Creek.<br />

Based on adult sockeye samples collected, 83.24% were age 1.2, 7.63% were age 1.3, 8.75%<br />

were age 2.2, 0.19% were age 1.4, and 0.19% were age 2.3. Of the returning salmon population,<br />

47% were male and 53% were female. The average length of adult sockeye population was 488<br />

mm. The average length of adult sockeye males was 496 mm and average length of adult<br />

sockeye females was 481 mm.<br />

The 2007 Shell <strong>Lake</strong> smolt migration was enumerated from 28 May and continued daily until 26<br />

June. During this time, an estimated 80,600 (±68,600) sockeye (O. nerka) smolts and 70 (±23)<br />

coho (O. kisutch) smolts migrated from Shell <strong>Lake</strong>. Personnel conducted the 10% sub-sampling<br />

procedure to estimate 68%, or 55,010 (±68,600), of the sockeye smolts and 29%, or 20 (±23), of<br />

the coho smolts were sub-sampled.<br />

Based on the sockeye smolt samples collected, an estimated 95% (±0.02%) were age 1 and 4%<br />

(±1.08%) were age 2. The average length and weight of age 1 sockeye smolt were 110 mm<br />

(±0.6 mm) and 12.7 g (±0.3 g). The average length and weight of age 2 sockeye smolt were 143<br />

mm (±11 mm) and 27.7 g (±5.7 g).<br />

Too few Coho smolt samples were collected to statistically evaluate during the smolt migration.<br />

The 2007 Shell <strong>Lake</strong> adult salmon escapement was enumerated from 16 July and continued daily<br />

until 13 September. During this time, 26,863 adult sockeye (O. nerka) and 6 adult coho (O.<br />

kisutch) salmon returned to Shell Creek. Two habitat surveys were conducted and observed<br />

active beaver dams hindering the migration of fish into Shell <strong>Lake</strong>. Fish were observed below<br />

the lowest dam and at the confluence of Shell Creek and Skwentna River. CIAA crew notched<br />

active beaver dams by hand to allow the passage of fish into the lake.<br />

Based on adult sockeye samples collected, 3.23% were age 1.2, 87.65% were age 1.3, 0.29%<br />

were age 2.2 and 8.82% were age 2.3. Of the returning salmon population, 46% were male and<br />

56% were female. The average length of adult sockeye population was 535 mm. The average<br />

length of adult sockeye males was 548 mm. The average length of adult sockeye females was<br />

523 mm.<br />

During the 2007 adult salmon escapement, CIAA conducted fecundity sampling to assist<br />

ADF&G estimate the maximum reproductive potential of the Shell <strong>Lake</strong> sockeye salmon<br />

population.<br />

The 2008 Shell <strong>Lake</strong> smolt migration was enumerated from 4 June and continued daily until 28<br />

June. During this time, an estimated 3,200 sockeye (O. nerka) and 30 coho (O. kisutch) smolts<br />

xi


migrated from the lake.<br />

Based on the sockeye smolt samples collected, an estimated 84% (±0.1%) were age 1 and 16%<br />

(±0.8%) were age 2. The average length and weight of age 1 sockeye smolt were 100 mm (±0.8<br />

mm) and 9.0 g (±0.9 g). The average length and weight of age 2 sockeye smolt were 137 mm<br />

(±3.8 mm) and 20.2 g (±1.9 g).<br />

Too few Coho smolt samples were collected to statistically evaluate during the smolt migration.<br />

The 2008 Shell <strong>Lake</strong> adult salmon escapement was enumerated from 14 July and continued daily<br />

until 3 September. During this time, 2,620 adult sockeye (O. nerka) salmon returned to Shell<br />

Creek.<br />

Based on adult sockeye samples collected, 8.69% were age 1.1, 17.07% were age 1.2, 53.73%<br />

were age 1.3, 1.37% were age 1.4, 0.69% were age 2.1, 13.91% were age 2.2, 4.19% were age<br />

2.3, and 0.34% were age 3.3. Of the returning salmon population, 34% were male and 66% were<br />

female. The average length of adult sockeye population was 511 mm. The average length of<br />

adult sockeye males was 539 mm. The average length of adult sockeye females was 496 mm.<br />

In Spring 2009, an ash plume emitted from Mt. Redoubt was carried north by winds and settled<br />

in the Skwenta and Talkeetna areas. Shell <strong>Lake</strong> accumulated a heavy fall of ash which resulted<br />

in an earlier than usual ice-out. Based on Shell <strong>Lake</strong> residents’ reports, ice-out occurred on 14<br />

May and field crew began monitoring on 16 May. The 2009 Shell <strong>Lake</strong> smolt migration was<br />

enumerated from 16 May and continued daily until 24 June. During this time, an estimated<br />

68,700 (±8,700) sockeye (O. nerka) and 7 coho (O. kisutch) smolts migrated from the lake.<br />

Personnel conducted the 10% sub-sampling procedure to estimate 64%, or 44,120 (±8,700), of<br />

the sockeye smolts were sub-sampled.<br />

Based on the sockeye smolt samples collected, an estimated 94% (±0.01%) were age 1 and 6%<br />

(±0.4%) were age 2. The average length and weight of age 1 sockeye smolt were 101 mm (±0.6<br />

mm) and 10.6 g (±0.3 g). The average length and weight of age 2 sockeye smolt were 149 mm<br />

(±4 mm) and 28.9 g (±2.2 g).<br />

Too few Coho smolt samples were collected to statistically evaluate during the smolt migration.<br />

Water chemistry and zooplankton samples were collected 4 times during 2007, 5 times in 2008,<br />

and 5 times in 2009. A summary of average open water quality characteristics are listed in Table<br />

1. ADF&G provided the analysis.<br />

INTRODUCTION AND PURPOSE<br />

To better understand the recent unexpected low adult sockeye returns to Upper <strong>Cook</strong> <strong>Inlet</strong>, <strong>Cook</strong><br />

<strong>Inlet</strong> <strong>Aquaculture</strong> <strong>Association</strong> (CIAA) is conducting a complete enumeration of both the juvenile<br />

and adult migrations on seven lakes thought to be key sockeye salmon producers in the Upper<br />

<strong>Cook</strong> <strong>Inlet</strong> drainage. Understanding the adult to juvenile relationship will allow management<br />

biologists to analyze and evaluate the production and rearing conditions of each lake. In addition<br />

to the collection of physical data on juvenile and adult salmon, CIAA is also collecting water<br />

quality measurements to better understand the entire salmon life cycle. Our goal is to collect<br />

sound biological data to provide the foundation on which decisions for management and<br />

rehabilitation strategies will be drawn.<br />

The smolt and adult enumeration studies and water quality measurements being collected by<br />

CIAA are part of a large effort by the <strong>Alaska</strong> Department of Fish and Game (ADF&G) to assess<br />

the salmon rearing environment of the Upper <strong>Cook</strong> <strong>Inlet</strong> drainage. To assist ADF&G, CIAA<br />

collected genetic samples from adult fish for analysis and recorded adult fish marked with a<br />

Passive Integrated Transponder tag for a mark-recapture study being conducted by ADF&G.<br />

ADF&G is also conducting a fall hydroacoustic analysis to survey fry production in each lake.<br />

All information recorded by CIAA is provided to ADF&G.<br />

Limnological Sampling<br />

METHODS<br />

Assessments of water quality were started during the 2006 adult escapement and continued<br />

during open water season through the 2009 adult escapement. One primary site was sampled for<br />

dissolved oxygen, temperature, light transmission profile, Secchi disk transparency, and<br />

zooplankton densities. Samples for analysis of phosphorous, carbon, chlorophyll a, phaeophytin<br />

a, nitrogen, calcium, magnesium, iron, conductivity, pH, alkalinity, turbidity, and color were also<br />

collected with a Kemmerer sampler one meter below the surface and from the midhypolimnion.<br />

One secondary site was limited to the zooplankton density and Secchi disk transparency. Water<br />

samples were collected by CIAA and water analysis completed by ADF&G. Sample collection<br />

and analysis procedures are described by Koenings, et al. (1986).<br />

Environmental Conditions<br />

Percent cloud cover was visually estimated, stream stage was measured to the nearest tenth of a<br />

foot, precipitation measured to the nearest millimeter and water and air temperatures were<br />

recorded at 5:00 PM each day. Stream stage measurements were not comparative between<br />

seasons as staff gage location varied from year to year. Standard CIAA procedures were<br />

followed for collecting these observations (CIAA, 2006).<br />

Smolt Enumeration<br />

To enumerate the smolt migration, a smolt trap was temporarily placed in Shell Creek. The<br />

smolt trap consisted of a modified fyke net with Vexar® netting leads and a double compartment<br />

live-box. The leads and fyke net funneled migrating smolt into the live-box. A swing gate<br />

remotely controlled by the trap operators directed smolt into one of two live-box compartments<br />

where they were enumerated and a smolt sample was collected.<br />

A total count of smolt migrating from Shell <strong>Lake</strong> was made until the migration of fish exceeded<br />

1,000 to 2,000 fish per hour. At migrations rates greater than 2,000 fish per hour, fish densities<br />

in the trap become too great and the fish become stressed. To avoid stressing the fish during<br />

periods of peak migration, a 10% sub-sampling procedure was used to enumerate the fish.<br />

5


To enumerate migrating smolt with the 10% sub-sampling procedure, the counting period was<br />

divided into 20-minute intervals. During each 20-minute interval, migrating fish were directed<br />

into the live-box for two minutes and counted. During the remaining 18 minutes, migrating<br />

smolt passed through the trap uncounted. To estimate the number of smolt migrating during the<br />

20-minute interval, the two-minute smolt count was multiplied by 10.<br />

Assuming the two-minute sub-sampling intervals were randomly distributed throughout subsampling<br />

1 and smolt moved through the weir randomly, the total smolt migration was estimated<br />

as follows:<br />

If:<br />

T<br />

c<br />

=<br />

number of fish counted with the total count procedure,<br />

Tˆ =<br />

s<br />

Tˆ =<br />

the total smolt migration,<br />

the number of fish counted in each two minute sub-sampling interval,<br />

the number of two minute sub-sampling intervals sampled, and<br />

the number of possible two minute sub-sampling intervals,<br />

Then, the total smolt migration (Tˆ ) is:<br />

with a variance of:<br />

T<br />

T T<br />

c s ;<br />

and 95% confidence limits of:<br />

Tˆ 2 v ˆ .<br />

s<br />

T s<br />

The variance about the estimated smolt migration, T , is equal to the variance about T s , because<br />

T c<br />

is a total count with 0 variance.<br />

1 Predetermined random 2-minute sampling intervals assured random distribution within each 20-minute period.<br />

The smolt characteristics of Shell <strong>Lake</strong> were assessed by collecting a sample of the migrating<br />

smolts to determine length and weight characteristics of the population. During the 2007, 2008,<br />

and 2009 smolt migrations, sockeye samples were collected at an interval of n=40 per day and<br />

coho samples were collected at an interval of n=20 per day. Field personnel collected samples<br />

randomly throughout each day. Each smolt collected for evaluation was first measured to the<br />

nearest millimeter for fork length 2 and then weighed to the nearest 0.1 gram. Several scales were<br />

also removed from the primary growth area 3 and mounted on a glass slide for subsequent age<br />

determination. Scale samples were read by CIAA full-time staff at headquarters in <strong>Kenai</strong>.<br />

During the 2007 smolt migration, 464 sockeye smolt scale samples were collected and read.<br />

During the 2008 smolt migration, 266 sockeye smolt scales samples were collected of which 254<br />

were readable. During the 2009 smolt migration, 957 sockeye smolt samples were collected of<br />

which 956 were readable. Samples collected for coho smolt during the 2007, 2008, and 2009<br />

migrations did not give a statistically representative estimate of the population and were not<br />

included in this report.<br />

Adult Enumeration<br />

The escapement enumeration includes an assessment of the sex, age, and standard fork length 4 of<br />

the returning population of fish. To enumerate returning adult salmon and facilitate data<br />

collection, a counting weir was temporarily installed in Shell Creek in 2006, 2007, and 2008.<br />

The weir was constructed of 1.9 cm galvanized pipe and 7.6 cm aluminum channel. The<br />

galvanized pipe was picketed through 1.9 cm holes in the aluminum channel spaced 2.54 cm<br />

apart.<br />

Field personnel visually counted the adult fish as they ascended Shell Creek. By removing one<br />

or two pickets fish were permitted to pass through the weir. Initially counts were made at least<br />

twice a day. As the number of fish ascending Shell Creek increased, counts were made more<br />

frequently to prevent fish from accumulating behind the weir. Personnel also checked for<br />

ADF&G tags on adult sockeyes passing through the weir.<br />

2 Standard fork length was measured from the tip of the snout to the fork of the tail.<br />

3 The primary growth area is located above the lateral line on a diagonal from the posterior insertion of the dorsal fin to the anterior insertion of the anal fin..<br />

4Standard fork length was defined as the measurement from mid-eye to the fork of the tail.<br />

7


The adult characteristics of Shell <strong>Lake</strong> were assessed by collecting a sample of the migrating<br />

adult sockeye salmon to determine age, length, and sex characteristics of the population. During<br />

the 2006, 2007, and 2008 adult escapements, sockeye samples were randomly collected at an<br />

interval of n=40 per day. Each adult sockeye collected for evaluation was first measured to the<br />

nearest millimeter for standard fork length 4 , and estimated sex. For age evaluation, field<br />

personnel removed a scale from the primary growth area 3 . The fish were unharmed and released<br />

upstream. Scale samples were sent to the ADF&G Soldotna office for analysis.<br />

During the 2006 adult escapement, 537 scale samples were analyzed for age. During the 2007<br />

adult escapement, 379 scale samples were collected of which 340 samples were analyzed for age.<br />

During the 2008 adult escapement, 365 scale samples were collected of which 286 samples were<br />

analyzed for age. During the 2009 adult escapement, 642 scale samples were collected of which<br />

569 samples were analyzed for age.<br />

Fecundity<br />

During the 2007 Shell <strong>Lake</strong> adult salmon escapement, CIAA crew conducted fecundity sampling<br />

on sockeye salmon. One of the objectives of the sockeye salmon study is an assessment of the<br />

reproductive potential of the sockeye salmon populations of the Susitna River basin. A key<br />

component of this assessment is an accurate estimate of the average fecundity of the sockeye<br />

population in each study lake. Fecundity is simply the number of eggs per female. In<br />

combination with the escapement, it represents the maximum reproductive potential of the<br />

population.<br />

To obtain an accurate estimate of average fecundity an attempt was made to collect and sacrifice<br />

10 females from each of the 12 size classes; 450-460 mm, 460-470 mm, 470-480 mm, 480-490<br />

mm, 490-500 mm, 500-510 mm, 510-520 mm, 520-530 mm, 530-540 mm, 540-550 mm, 550-<br />

560 mm, and 560-570 mm. Field personnel were instructed to select specimens randomly<br />

throughout the escapement. Once the fish was measured for length and scale sample, each ovary<br />

was removed and weighed to the nearest 0.1 g. Thirty to forty eggs were then collected from the<br />

anterior, middle and posterior portion from only one ovary. Either ovary may be sampled;<br />

8


however one ovary should not dominate within the size class. Each sample of eggs was weighed<br />

to the nearest 0.1 g.<br />

The average fecundity was estimated as follows:<br />

Where:<br />

F = fecundity,<br />

N A = number of eggs in the sample from the anterior portion of the ovary,<br />

N M = number of eggs in the sample from the middle portion of the ovary,<br />

N P = number of eggs in the sample from the posterior portion of the ovary,<br />

W A = weight of egg sample from the anterior portion of the ovary,<br />

W M = weight of egg sample from the posterior portion of the ovary, and<br />

W L+R = combined weight of both ovaries.<br />

RESULTS AND DISCUSSION<br />

Limnological Conditions<br />

Limnological conditions are a key component in understanding Shell <strong>Lake</strong> productivity and<br />

rearing conditions in this monitoring study. Water chemistry and zooplankton were conducted 3<br />

times in 2006. In 2007, water chemistry and zooplankton samples were collected 4 times. In<br />

2008, water chemistry and zooplankton samples were collected 5 times. In 2009, water<br />

chemistry and zooplankton data were collected 5 times. A summary of limnological conditions<br />

is listed in Table 1. ADF&G provided the analysis for limnological conditions.<br />

Environmental Conditions<br />

During the 2006 adult sockeye migration environmental conditions were monitored from 15 July<br />

to 21 August. Due to a delay in delivery of environmental apparatus, data was not recorded for<br />

11


stream stage measurements, rainfall, stream and air temperatures. None of the days were clear,<br />

30% were partly cloudy, 16% were mostly cloudy, and 54% were completely overcast.<br />

During the 2007 smolt migration, environmental conditions were monitored from 30 May to 26<br />

June. Stream stage measurements averaged 1.58 feet and ranged from 1.35 to 1.79 feet. Stream<br />

temperatures averaged 13 C and ranged from 7 to 22 C. Air temperatures averaged 18 C and<br />

ranged from 10 to 26 C. Thirty-two percent of the days were clear, 36% were partly cloudy, and<br />

25% were completely overcast. Measurable rain was recorded on 11 days during the smolt<br />

migration. A total of 309 mm of rain fell during this period.<br />

During the 2007 adult escapement, environmental conditions were monitored from 16 July to 13<br />

September. Stream stage measurements averaged 1.24 feet and ranged from 1.09 to 1.40 feet.<br />

Stream temperatures averaged 16 C and ranged from 11 to 23 C. Air temperatures averaged<br />

18 C and ranged from 10 to 29 C. Thirteen percent of the days were clear, 30% were partly<br />

cloudy, and 33% were completely overcast. Measurable rain was recorded on 24 days during the<br />

adult escapement. A total of 130 mm of rain fell during this period.<br />

During the 2008 smolt migration, environmental conditions were monitored from 4 June to 28<br />

June. Stream stage measurements averaged 1.43 feet and ranged from 0.99 to 2.03 feet. Stream<br />

temperatures averaged 11 C and ranged from 7 to 17 C. Air temperatures averaged 20 C and<br />

ranged from 12 to 29 C. None of the days were clear, 24% were partly cloudy, and 32% were<br />

completely overcast. Measurable rain was recorded on 12 days during the smolt migration. A<br />

total of 17 mm of rain fell during this period.<br />

During the 2008 adult escapement, environmental conditions were monitored from 14 July to 3<br />

September. Stream stage measurements averaged 0.73 feet and ranged from 0.56 to 0.90 feet.<br />

Stream temperatures averaged 15 C and ranged from 11 to 18 C. Air temperatures averaged<br />

20 C and ranged from 12 to 31 C. Four percent of the days were clear, 23% were partly cloudy,<br />

and 44% were completely overcast. Measurable rain was recorded on 21 days during the adult<br />

escapement. A total of 108 mm of rain fell during this period.<br />

12


During the 2009 smolt migration, environmental conditions were monitored from 16 May to 24<br />

June. Stream stage measurements averaged 1.04 feet and ranged from 0.70 to 1.60 feet. Stream<br />

temperatures averaged 13 C and ranged from 6 to 21 C. Air temperatures averaged 18 C and<br />

ranged from 8 to 28 C. Ten percent of the days were clear, 39% were partly cloudy, and 24%<br />

were completely overcast. Measurable rain was recorded on 15 days during the smolt migration.<br />

A total of 29 mm of rain fell during this period.<br />

Smolt Enumeration<br />

The 2007 Shell <strong>Lake</strong> smolt migration was enumerated from 28 May and continued daily until 26<br />

June. During this time, an estimated 80,600 (±68,600) sockeye (O. nerka) smolts and 70 (±23)<br />

coho (O. kisutch) smolts migrated from Shell <strong>Lake</strong>. Personnel conducted the 10% sub-sampling<br />

procedure to estimate 68%, or 55,010 (±68,600), of the sockeye smolts and 29%, or 20 (±23), of<br />

the coho smolts were sub-sampled. Other fish counted included 1 chinook (O. tshawytscha)<br />

smolt. Based on the sockeye smolt samples, an estimated 95% (±0.02%) were age 1 and 4%<br />

(±1.08%) were age 2. The average length and weight of age 1 sockeye smolt were 110 mm<br />

(±0.6 mm) and 12.7 g (±0.3 g). The average length and weight of age 2 sockeye smolt were 143<br />

mm (±10.6 mm) and 27.7 g (±5.7 g).<br />

The 2008 smolt migration was enumerated from 4 June and continued daily until 28 June.<br />

During this time 3,200 sockeye (O. nerka) and 23 coho (O. kisutch) smolts migrated from the<br />

lake. Based on the sockeye smolt samples collected, an estimated 84% (±0.1%) were age 1 and<br />

16% (±0.8%) were age 2. The average length and weight of age 1 sockeye smolt were 100 mm<br />

(±0.8 mm) and 9.0 g (±0.9 g). The average length and weight of age 2 sockeye smolt were 137<br />

mm (±3.8 mm) and 20.2 g (±1.9 g). Other fish counted was 1 northern pike. CIAA crew<br />

captured the fish in the smolt trap, examined the stomach contents and counted 36 sockeye<br />

smolts.<br />

There are three reasons for lower than expected number of smolts during the 2008 smolt<br />

enumeration. First, CIAA suspected that a large percentage of smolts migrated from the lake<br />

before monitoring began on 4 June. Second, the smolt trap was placed in the slow current which<br />

13


allowed migrating smolt the ability to move out of the trap and travel back to the lake. Third,<br />

field personnel spent an insufficient amount of time managing the trap site. The crew inspected<br />

the trap 2 to 5 times per night for up to 20 minute intervals. The combination of late trap<br />

construction, poor trap location, and insufficient time managing the trap may have resulted in<br />

some late-migrating smolt holding over in Shell <strong>Lake</strong> for another year. Based on the age<br />

structure of the 2009 smolt migration, the number of fish holding over in Shell <strong>Lake</strong> was not<br />

believed to be large.<br />

In Spring 2009, an ash plume emitted from Mt. Redoubt was carried north by winds and settled<br />

in the Skwenta and Talkeetna areas. Shell <strong>Lake</strong> accumulated a heavy fall of ash which resulted<br />

in an earlier than usual ice-out. Based on Shell <strong>Lake</strong> residents’ reports, ice-out occurred on 14<br />

May and field crew began monitoring on 16 May. The 2009 Shell <strong>Lake</strong> smolt migration was<br />

enumerated from 16 May and continued daily until 24 June. During this time, an estimated<br />

68,700 (±8,700) sockeye (O. nerka) and 7 coho (O. kisutch) smolts migrated from the lake.<br />

Personnel conducted the 10% sub-sampling procedure to estimate 64%, or 44,120 (±8,700), of<br />

the sockeye smolts were sub-sampled. Based on the sockeye smolt samples collected, an<br />

estimated 94% (±0.01%) were age 1 and 6% (±0.4%) were age 2. The average length and<br />

weight of age 1 sockeye smolt were 101 mm (±0.6 mm) and 10.6 g (±0.3 g). The average length<br />

and weight of age 2 sockeye smolt were 149 mm (±4 mm) and 28.9 g (±2.2 g). Based on the<br />

reported ice-out on 14 May, the smolt migration monitoring was considered to be complete.<br />

During the 2007, 2008, and 2009 smolt migrations, field personnel have seen northern pike in<br />

Shell Creek but were unable to conduct a statistically valid enumeration.<br />

Adult Enumeration<br />

The adult escapement was enumerated from 15 July and continued daily until 19 August when<br />

the weir became inoperable due to extreme flooding conditions. During this time 69,800 adult<br />

sockeye (O. nerka) salmon returned to Shell Creek. Other fish counted during this time were 21<br />

pink (O. gorbuscha) salmon, 1 chum (O. keta) salmon and 1 northern pike. Adult enumeration<br />

was terminated early due to extreme flooding conditions throughout the Susitna drainage. Based<br />

on 2007 and 2009 escapement counts, CIAA suspected a majority of fish were enumerated<br />

before monitoring ended.<br />

Based on adult sockeye samples collected, 83.24% were age 1.2, 7.63% were age 1.3, 8.75%<br />

were age 2.2, 0.19% were age 1.4, and 0.19% were age 2.3. Of the returning salmon population,<br />

47% were male and 53% were female. The average length of adult sockeye population was 488<br />

mm. The average length of adult sockeye males was 496 mm. The average length of adult<br />

sockeye females was 481 mm.<br />

ADF&G Gene Conservation Lab in Anchorage conducted a Finfish DNA Analysis to determine<br />

the genetic characteristics and profile of the sockeye population at Shell <strong>Lake</strong>. CIAA crew<br />

randomly collected axillary processes of adult sockeye salmon returning to the lake and samples<br />

were sent to ADF&G Gene Conservation Lab in Anchorage for analysis. ADF&G Gene<br />

Conservation Lab provided CIAA with sampling procedures. CIAA also assisted ADF&G Sport<br />

Division with a Sockeye Mark-Recapture PIT tag study. Field personnel scanned 35 PIT tags<br />

during the adult escapement. ADF&G Sport Division provided the procedures and analysis.<br />

The 2007 Shell <strong>Lake</strong> adult salmon escapement was enumerated from 16 July to13 September.<br />

During this time 26,863 adult sockeye (O. nerka) and 6 adult coho (O. kisutch) salmon returned<br />

to Shell Creek. Other fish counted during this time were 2 adult pink (O. gorbuscha) salmon, 1<br />

adult chum (O. keta), and 1 adult rainbow trout.<br />

Shell <strong>Lake</strong> residents on two occasions reported of beaver dams hindering the migration of<br />

salmon into the lake. On 4 August 2007, a habitat survey was conducted by the CIAA field crew<br />

where the entire creek was surveyed by helicopter. The crew observed 2 active beaver dams<br />

15


with fish holding below the lowest dam. Fish were also observed holding at the confluence of<br />

the Skwentna River where poor visibility made an estimate of the number of fish impossible.<br />

The crew notched both beaver dams, observing no fish ascending the dams while the crew was<br />

on-site. From 16 July to August 4, no fish were seen at the outlet where CIAA crew operated the<br />

weir. On 5 August 2007, CIAA crew counted and passed 7,911 sockeye salmon into Shell <strong>Lake</strong>.<br />

On 21 August 2007, a second habitat survey was conducted by CIAA crew where the entire<br />

creek was surveyed by helicopter. The crew identified 1 active beaver dam with less than 25 fish<br />

holding below it. Fish were also observed holding at the confluence of the Skwentna River<br />

where poor visibility made an estimate of the number of fish impossible. CIAA crew notched<br />

the active beaver dam and no fish were observed ascending the dam while on-site.<br />

Based on adult sockeye samples collected, 3.23% were age 1.2, 87.65% were age 1.3, 0.29%<br />

were age 2.2 and 8.82% were age 2.3. Of the returning salmon population, 46% were male and<br />

56% were female. The average length of adult sockeye population was 535 mm. The average<br />

length of adult sockeye males was 548 mm. The average length of adult sockeye females was<br />

523 mm.<br />

ADF&G Gene Conservation Lab in Anchorage conducted a Finfish DNA Analysis to determine<br />

the genetic characteristics and profile of the sockeye population at Shell <strong>Lake</strong>. CIAA crew<br />

randomly collected axillary processes of adult sockeye salmon returning to the lake and samples<br />

were sent to ADF&G Gene Conservation Lab in Anchorage for analysis. ADF&G Gene<br />

Conservation Lab provided CIAA with sampling procedures.<br />

During the 2007 adult salmon escapement, fecundity was sampled to assess the reproductive<br />

potential of the sockeye salmon population at Shell <strong>Lake</strong>. Table 3 shows the average number of<br />

eggs per female for each size class.<br />

The 2008 Shell <strong>Lake</strong> adult salmon escapement was enumerated from 14 July to 3 September.<br />

During this time 2,620 adult sockeye (O. nerka) salmon returned to Shell Creek. Other fish<br />

counted during this time were 5 adult pink (O. gorbuscha) salmon.<br />

Based on adult sockeye samples collected, 8.69% were age 1.1, 17.07% were age 1.2, 53.73%<br />

were age 1.3, 1.37% were age 1.4, 0.69% were age 2.1, 13.91% were age 2.2, 4.19% were age<br />

2.3, and 0.34% were age 3.3. Of the returning salmon population, 34% were male and 66% were<br />

female. The average length of adult sockeye population was 511 mm. The average length of<br />

adult sockeye males was 539 mm. The average length of adult sockeye females was 496 mm. A<br />

summary of 2006-2008 adult sockeye characteristics is listed in Table 4.<br />

During the 2006, 2007, and 2008 adult escapements, field personnel have seen northern pike in<br />

Shell Creek but were unable to conduct a statistically valid enumeration.<br />

RECOMMENDATIONS<br />

Shell <strong>Lake</strong> is one of the major sockeye salmon rearing lakes in the Susitna drainage. The<br />

project should continue to collect data consistent with the previous study during smolt<br />

migrations and adult escapements to provide further comparative data. Based on<br />

observations from Shell <strong>Lake</strong> residents, ice-out occurs around 28 May. Increased efforts to<br />

begin the smolt enumeration closer to this date in 2010 should be undertaken in order to<br />

monitor the beginning of the smolt migration.<br />
