TLH PAR 2-5-16 - Statement of Goals and Objectives Nature of the Requested Alteration: This alteration request modifies the Trail Lakes Hatchery (TLH) Basic Management Plan (BMP) by:
Allowing CIAA to increase the number of green sockeye salmon eggs from English Bay Lake stock (Tutka Bay Lagoon returns) to 5,507,000 from the currently permitted maximum of 5,372,000 (increase of 135,000 green sockeye salmon eggs).
Allows CIAA to stock 90,000 English Bay Lakes stock sockeye salmon smolt to Martin Ponds (Lower Pond) at the head of Kachemak Bay. Adult sockeye salmon returns will be used as future broodstock for the Lower Cook Inlet (LCI) stocking programs.
Why is the Alteration Being Requested: The purpose of this request is to: Prior to 2004, the stock used for the LCI broodstock program was from Tustumena Lake. This stock was not only used at Hazel, Leisure and Kirschner lakes, and Tutka Bay Lagoon but also at Chenik, Ursus, Bruin, Port Dick, Upper Paint, and Lower Paint lakes. In December of 2003, the 9th Circuit Court ruled the Tustumena Lake enhancement project was a commercial enterprise which violated the 1962 Wilderness Act and ordered the project be terminated. To continue with the LCI program, CIAA along with the Alaska Department of Fish and Game (ADFG) investigated alternative brood sources. Between 2005 and 2009, CIAA collected additional eggs from the Hidden Lake program to serve as the temporary brood source for the LCI program and to develop a return to Tutka Bay Lagoon to serve as a future brood source. Without a freshwater source (lake or river) for these fish to naturally ripen, CIAA implemented the use of a lensing bag to ripen the broodstock. This lensing bag is situated within the net pen structure in Tutka Bay Lagoon. Freshwater from the hatchery is directed into this bag and essentially creates a "pond" of freshwater allowing fish to ripen. Although the use of lensing bags is a sufficient method of ripening fish, there are some setbacks or disadvantages. Firstly, freshwater must be supplied consistently. Any stoppage in the flow of freshwater can cause saltwater to enter the bag and because the fish have made the necessary physiological adjustments to reside in freshwater, they are not able to survive the saltwater intrusion. Secondly, the exchange of freshwater in the bag is low. This creates an environment in which the health of the broodstock is jeopardized. The Hidden Lake stock returns to the LCI release locations also proved to be lower in number, later in terms of timing and smaller in size. These three factors combined decreased the economic value of adult sockeye salmon returns to the fishery. Table 1 demonstrates the average return and economic value associated with the Tustumena Lake stock returns versus the Hidden Lake stock returns.

Data taken from ADF&G, Fisheries Management Report No. 15-32, Appendix F15, F17, F18 aData from 2003 is excluded as the returns this year were an anomaly. It is hypothesized that these returns were from Kenai stock that got blown into the area because of storms and currents during that time. bFor English Bay Lakes stocks, economic value is calculated using a fish size of 4.5 lb and $1.70/lb. For the Hidden Lake and Tustumena Lake stocks, economic value is calculated using a fish size of 4.0 lb and $1.70/lb (Tustumena) and $1.50/lb (Hidden) to reflect the later returns. Recognizing the unsuitability of the Hidden Lake stock as a replacement for the Tustumena Lake stock, CIAA and ADFG once again looked at alternatives for a broodstock source. In 2011, CIAA began the transition of using the earlier-run English Bay Lakes stock instead of the late-run Hidden Lake broodstock. Additional sockeye salmon eggs were initially collected from the English Bay Lakes system as donor stock until English Bay Lakes stock adult returns were sufficient at Tutka Bay Lagoon. This transition was completed in 2015. Although not all LCI release locations have seen the adult returns of the English Bay Lakes stock, the adult returns were seen at Kirschner and Tutka Bay Lagoon. Preliminary evaluation indicates that the issues associated with the Hidden Lake stock (small fish, lower number of returns and late timing) are no longer prevalent and the economic value of the fishery is improving (see Table 1; Kirschner and Tutka Bay Lagoon). In 2011, CIAA made the decision to reopen Tutka Bay Lagoon Hatchery for the production of pink salmon. The freshwater demands for the incubation of pink salmon in the hatchery and for ripening of sockeye salmon in the lensing bag exceed the maximum freshwater capacity allowed both in terms of permitting and pumping. This situation has led to a compromise in both the pink and sockeye programs. The result is that CIAA is unable to obtain egg targets necessary to support all LCI stocking programs both in terms of pink and sockeye production. This inability to meet egg target goals has a negative impact on the economic value of the fishery. In 2014, CIAA began discussions with ADFG to find an alternative location for the LCI broodstock program. A suitable site has still not been established. Expecting a large pink salmon return to Tutka Bay Lagoon and hence a full hatchery of eggs, CIAA made the decision to temporarily relocated the sockeye broodstock ripening program to its Port Graham Hatchery in 2015—
where less conflict was expected because the Port Graham pink program was just starting. Adult sockeye salmon returning to Tutka Bay Lagoon were captured and transported via seine boat to the lensing bag located in net pens at Port Graham Bay. Environmental conditions, excessive handling and capture stress led to nearly all of the sockeye broodstock being lost. Although additional broodstock were captured from adult sockeye salmon returns to Kirschner Lake, this was not sufficient to meet the egg target goals for all release locations. Both Hazel and Leisure lakes will not be stocked with fry in 2016. As indicated in Table 2, this loss of stocking to these two locations will result in a reduced adult return by nearly 98,000 fish, thus having a substantial negative impact on the value to the fishery (loss of $779,025). Table 2. Estimated adult sockeye salmon returns and economic value to the fishery if stocking goals at each location are achieved.

Total 4,000,000 177,500 834,250 $1,418,225 The LCI broodstock program has had difficulties becoming firmly established and secure since the 9th Circuit Court ordered termination of the Tustumena Lake program in 2003. This lack of security has impacted both the financial footing of CIAA and the common property fishery. Without a location in which fish can return relatively free of sport and commercial fishing pressure, and be allowed to ripen naturally in freshwater without the use of a lensing bag, the health of the broodstock program as well as those locations that rely on the progeny from these broodstock and gamete collections are in jeopardy. Without a secure broodstock, the potential loss to the fishery is approximately $1.4 million (Table 2). What is Expected to be Accomplished by the Alteration: At this time, CIAA is proposing to stock up to 90,000 English Bay Lakes stock sockeye salmon smolt at Martin River Delta Ponds on an annual basis beginning in 2017 (April/May). Assuming a 10% survival and a 30% harvest rate during their migration to the head of Kachemak Bay (set net and purse seine), the expected adult return to the ponds will be 6,300 fish. Assuming a 15% mortality rate while ripening in the ponds, approximately 5,355 broodstock would be available for gamete collection. The progeny from this gamete collection will be stocked at Tutka Bay Lagoon and Hazel, Kirschner and Leisure lakes providing an economic value to the LCI fishery of over $1.4 million.
Will the Alteration Affect Wild Salmon Stocks or Existing Fisheries: The head of Kachemak Bay is a large delta supplied not only by the water flows from the Martin River and Battle Creek but also from Bradley River, Sheep Creek and Fox River (Figure 1). ADFG's geneticists expressed concern that the introduction of a hatchery stocking program could overwhelm the native stocks in the area. Because of the lack of an established fishery in the area due to small populations of salmon, very little evaluation and monitoring has been done in the area since the construction of the Bradley Lake Power Plant. No genetic sampling has been
performed on the stocks in this area. With this lack of data, the department believes it must follow the guidelines provided by the Genetics Policy and 5 AAC 39.222. Policy for the management of sustainable salmon fisheries (precautionary principle) and cannot support the project without additional information and appropriate precautionary measures be taken to protect the native stocks in the area. It is agreed by CIAA that there is a lack of current information in these waterbodies at the head of Kachemak Bay. This lack of activity is primarily driven by the resources available (time and money) in relation to the importance of these returns to the fishery. The number of salmon returning to the waterways in this area is low and contributes very little to the commercial fisheries. There is no sustainable escapement goals set for any of these waterways of concern. Historical estimates have the sockeye salmon population ranging at just over 2,000 fish for Fox River, 100–300 for Martin River and 100–300 for Bradley River. In the study completed by Northern Ecological Services (1995) which summarized the 10-year salmon study at Bradley River, they indicated that the sockeye salmon in the Bradley River showed a wide variation in size and time of maturity suggesting that they may be strays from other systems. The most recent study performed on Battle Creek in 2010 and 2011, also suggests that the sockeye salmon distribution is limited and intermittent (HDR, 2012). Table 3 provides the "as the crow flies" distances between the sample locations identified by ADFG. Considering the proximity of the other systems to Bradley River and the fact that Bradley River's sockeye population may be strays, it is likely that these sockeye salmon are all similar. Table 3.

In 2014, ADFG predicted a total harvest of 800 sockeye salmon in the Southern District from wild stocks in the area and another 114,900 coming from the hatchery production (Hollowell, G. et al., 2015). This demonstrates the importance that the hatchery production has to the fishery. Since the lost of the Tustumena Lake stock, CIAA has been struggling to have a consistent and secured broodstock for the LCI stocking programs. None of the options tried over the last 12–13 years have provided a solution that gives a consistent adult return to provide economic sustainability to not only CIAA but to the common property fishery as well. Using the average sockeye returns provided in Table 1, the loss of the Tustumena Lake stock decreased the value of the fishery by nearly 80%. Now with the change to the English Bay Lakes stock, CIAA sees a solution to reduce this loss to the fishery but only if a location is found where these fish can return naturally and allowed to ripen without stress of capture, handling and holding in lensing bags. Martin Ponds provides such a location.
Without a secure broodstock and consistent stocking program, CIAA will continue to struggle with the LCI stocking programs. This struggle will continue to force CIAA to collect more fish from other returns, for cost recovery to support the stocking programs. This negatively impacts on the common property fishery. While CIAA recognizes that ADFG is mandated by the sustainable fisheries policy to protect the wild stocks, they are also mandated by the same policy that the "...escapement monitoring programs be appropriate to the scale, intensity, and importance of each salmon stock's use..."(Alaska Administration Code: 5 AAC 39.222) Since there is limited current information on the wild stock in terms of escapement counts, run timing and genetic samples, it can be deduced that the importance of these wild populations to the fishery are low. Although it could be argued that CIAA's proposed activity now makes these population more important because of potential interactions, the level of stocking, the number of adults returning and what the progeny from these returns can potentially bring to the economic sustainability of the fishery ($1.4 million) is far more economically valuable to the State of Alaska. What Contribution will the Alteration Make to the Common Property Fisheries: The progeny from this gamete collection will be stocked at Tutka Bay Lagoon and Hazel, Kirschner and Leisure lakes providing an economic value to the LCI fishery of over $1.4 million. Without a secure broodstock and consistent stocking program, CIAA will continue to struggle with the LCI stocking programs. This struggle will continue to force CIAA to collect more fish from other returns, for cost recovery to support the stocking programs. This negatively impacts on the common property fishery. How Will Effects and Interactions between Introduced and Wild Stocks be Assessed: Feedback was provided by ADFG on what measures could be taken to provide information to fill in the data gaps and how these would be evaluated to either allow or disallow the project. This information is provided below:
Sampling of spawning sockeye salmon in Kachemak Bay for genetic analysis
o 96 adults or 192 juveniles per site o Axillary fin (in ethanol or dried on paper) together with age, sex, and length o Sampling over for 1 year and depending on initial results, a second year o Sample locations and priority:
1. Fox River 2. English Bay Lakes (GCL has samples from 1992, but would ideally like more
recent) or current Tutka broodstock (GCL has 131 samples from 2014, but not yet analyzed)
3. Martin River 4. Lower Bradley River
When possible, gather data on run timing among stocks of sockeye salmon in Kachemak Bay.
Analyze axillary fins for variability at 96 DNA SNPs to estimate population structure, allele-frequency stability and to measure genetic diversity.
Decision criteria Several factors can be considered in evaluating the genetic aspects of the proposed project. The following conditions will be used to assess the level of genetic risk to wild populations and will be used to evaluate the proposal from a genetics point of view.
Degree of differentiation of Martin River spawners from English Bay and other Kachemak Bay populations.
The extent that Martin River supports a self-sustaining population.
Run timing of fish released in Martin Ponds, relative to run timings of fish returning to the Martin River and nearby streams and rivers.
Steps to prevent mixing of hatchery and native stocks both in natural spawning and in brood selection or cost recovery harvest.
Manning the Martin Pond weir so as not to preclude use of the ponds by other species (e.g., coho).
Precautions to prevent the escape of hatchery-origin fish released into Martin Pond.
CIAA also understands the value of good scientific information. If this project is permitted to proceed, CIAA will have staff at Martin Ponds to monitor the weirs, enumerate salmon returning to the ponds and perform eggtake duties. Other than the days in which staff perform eggtakes or the peak of salmon returns, there will be opportunities for staff to collect samples from locations like Martin River, Red Lake1 and Bradley River. These three sites will be relatively easy for staff to access from the camp located near Martin Ponds via road system and 4-wheeler. Additionally, the heads from a portion of the fish (1%) used for spawning will be collected and the otoliths will be removed for later analysis. CIAA will also collect the axillary fin every 5 years for genetic analysis from 1% of the spawning population. The expertise to conduct monitoring and collect basic biological samples (species counts, sex, length, age, thermal mark identification and axillary fin sampling) is held by CIAA. However, CIAA does not have the expertise or equipment to perform the genetic analysis—CIAA would be looking to ADFG to assist with the genetic analysis. In the event that results indicate that there are negative impacts CIAA will implement corrective measures or stop all stocking efforts at Martin Ponds.
What Marking and Recovery Studies are Being Proposed: All hatchery stocked sockeye salmon will be thermally marked. If this project is permitted to proceed, CIAA will have staff at Martin Ponds to monitor the weirs, enumerate salmon returning to the ponds and perform eggtake duties. Other than the days in which staff perform eggtakes or the peak of salmon returns, there will be opportunities for staff to collect samples from locations like Martin River, Red Lake and Bradley River. These three sites will be relatively easy for staff to access from the camp located near Martin Ponds via road system and 4-wheeler. Additionally, the heads from a portion of the fish (1%) used for spawning will be collected and the otoliths will be removed for later analysis. CIAA will also collect the axillary fin every 5 years for genetic analysis from 1% of the spawning population.

However, CIAA does not have the expertise or equipment to perform the genetic analysis—CIAA would be looking to ADFG to assist with the genetic analysis. What are the Potential Benefits to Fisheries or Wild Stocks: In 2014, ADFG predicted a total harvest of 800 sockeye salmon in the Southern District from wild stocks in the area and another 114,900 coming from the hatchery production (Hollowell, G. et al., 2015). This demonstrates the importance that the hatchery production has to the fishery. The progeny from this gamete collection will be stocked at Tutka Bay Lagoon and Hazel, Kirschner and Leisure lakes providing an economic value to the LCI fishery of over $1.4 million. Without a secure broodstock and consistent stocking program, CIAA will continue to struggle with the LCI stocking programs. This struggle will continue to force CIAA to collect more fish from other returns, for cost recovery to support the stocking programs. This negatively impacts on the common property fishery. Has the Project been Discussed with the Area and/or Management Biologist: The Martin Ponds option was presented by CIAA to the Cook Inlet Regional Planning Team at a meeting held in December 2015. The use of these ponds for developing a return for a broodstock program was met with some apprehension from ADFG due to genetic concerns. It is noted that ADFG's pathologist provided comments as well but had no issues with the project and felt that ripening fish outside the lensing bag would improve broodstock health (Meyers, email communication, 2016).
Trail Lakes Hatchery
Permit Alteration Request ~ Martin Ponds
Additional Information
History of the Lower Cook Inlet Broodstock Program
The Trail Lakes Hatchery has five sockeye salmon broodstock programs:
1) Bear Lake ·which provides sockeye salmon eggs for the stocking programs at Bear lake and Resurrection Bay;
2) Hidden lake· which provides sockeye salmon eggs for the stocking programs at Hidden lake;
3) Shell lake· which provides sockeye salmon eggs for the stocking program at Shell lake;
4) English Bay lakes· which supplies the back·stocking program at English Bay lakes; and
5) lower Cook Inlet (lCI) ·which provides sockeye salmon eggs for the stocking programs at Hazel, leisure and Kirschner lakes as well as Tutka Bay lagoon.
The Bear lake and Hidden lake programs are long·established programs and the security and
development of the brood stock well coordinated and established among the different agencies. With
the exception of one year with the Bear lake program, Cook Inlet Aquaculture (CIAA) has consistently
been able to secure sufficient broodstock to maintain the programs. However, this has not been the
case with the LCI program.
Prior to 2004, the stock used for the lCI broodstock program was from Tustumena lake. This stock was
not only used at Hazel, Leisure and Kirschner lakes, and Tutka Bay lagoon but also at Chenik, Ursus,
Bruin, Port Dick, Upper Paint, and lower Paint lakes. In December of 2003, the 9th Circuit Court ruled
the Tustumena lake enhancement project was a commercial enterprise which violated the 1962
Wilderness Act and ordered the project be terminated.
To continue with the lCI program, CIAA along with the Alaska Department of Fish and Game (ADFG)
investigated alternative brood sources. Between 2005 and 2009, CIAA collected additional eggs from the
Hidden lake program to serve as the temporary brood source for the lCI program and to develop a
return to Tutka Bay Lagoon to serve as a future brood source. Without a freshwater source (lake or
river) for these fish to naturally ripen, CIAA implemented the use of a lensing bag to ripen the
broodstock. This lensing bag is situated within the net pen structure in Tutka Bay lagoon. Freshwater
from the hatchery is directed into this bag and essentially creates a "pond" of freshwater allowing fish to
ripen.
Although the use of lensing bags is a sufficient method of ripening fish, there are some setbacks or
disadvantages. Firstly, freshwater must be supplied consistently. Any stoppage in the flow of freshwater
can cause saltwater to enter the bag and because the fish have made the necessary physiological
adjustments to reside in freshwater, they are not able to survive the saltwater intrusion. Secondly, the

CIAA and ADFG once again looked at alternatives for a broodstock source. In 2011, CIAA began the
transition of using the earlier-run English Bay Lakes stock instead of the late-run Hidden Lake

indicates that the issues associated with the Hidden Lake stock (small fish, lower number of returns and
late timing) are no longer prevalent and the economic value of the fishery is improving (see Table 1;
Kirschner and Tutka Bay Lagoon).
In 2011, CIAA made the decision to reopen Tutka Bay lagoon Hatchery for the production of pink
salmon. The freshwater demands for the incubation of pink salmon in the hatchery and for ripening of
sockeye salmon in the lensing bag exceed the maximum freshwater capacity allowed both in terms of

mating cross and 10% inviable, a total of 5,060 broodstock are required (Table 4). Currently CIAA is
permitted to collect 6,720,000 green sockeye salmon eggs (6,370,000 English Bay Lakes/Tutka; 350,000
English Bay Lakes/English Bay Lakes). Assuming the first stocking takes place in 2017 (BY15), the first
returns would occur in 2019 as indicated in the below table (Table 5).

removed for later analysis. CIAA will also collect the axillary fin every 5 years for genetic analysis from
1% of the spawning population. All carcasses will be discarded by either disposal in Kachemak Bay or
transporting to Homer for disposal.
Alaska Department of Fish and Game Preliminary Response
The Martin Ponds option was presented by CIAA to the Cook Inlet Regional Planning Team at a meeting
held in December 2015. The use of these ponds for developing a return for a broodstock program was
met with some apprehension from ADFG due to genetic concerns. It is noted that ADFG's pathologist
provided comments as well but had no issues with the project and felt that ripening fish outside the
lensing bag would improve broodstock health (Meyers, email communication, 2016).
The head of Kachemak Bay is a large delta supplied not only by the water flows from the Martin River
and Battle Creek but also from Bradley River, Sheep Creek and Fox River (Figure 1). ADFG's geneticists
expressed concern that the introduction of a hatchery stocking program could overwhelm the native
stocks in the area. Because of the lack of an established fishery in the area due to small populations of
salmon, very little evaluation and monitoring has been done in the area since the construction of the
Bradley lake Power Plant. No genetic sampling has been performed on the stocks in this area. With this
lack of data, the department believes it must follow the guidelines provided by the Genetics Policy and
5 AAC 39.222. Policy for the management of sustainable salmon fisheries (precautionary principle) and

o 96 adults or 192 juveniles per site o Axillary fin (in ethanol or dried on paper} together with age, sex, and length o Sampling over for 1 year and depending on initial results, a second year o Sample locations and priority:
1. Fox River 2. English Bay Lakes (GCL has samples from 1992, but would ideally like more recent} or current
Tutko broodstock (GCL has 131 samples from 2014, but not yet analyzed} 3. Martin River 4. Lower Bradley River
• When possible, gather data 011 run timing among stocks of sockeye salmon in Kachemak Bay. • Analyze axillary fins for variability at 96 DNA SNPs to estimate population structure, allele-frequency
Several factors con be considered in evaluating the genetic aspects af the proposed project. The following conditions will be used to assess the level af genetic risk ta wild populations and will be used ta evaluate the proposal from a genetics point of view.
• Degree of differentiation af Martin River spawners from English Bay and other Kachemak Bay populations.
• The extent that Martin River supports a self-sustaining papulation. • Run timing of fish released in Martin Ponds, relative to run timings of fish returning ta the Martin River
and nearby streams and rivers. • Steps to prevent mixing of hatchery and native stocks both in natural spawning and in brood selection or
cost recovery harvest. • Manning the Martin Pond weir sa as not to preclude use of the ponds by other species (e.g., coho). • Precautions to prevent the escape of hatchery-origin fish released into Martin Pond.
Response by CIAA to Sampling Plan and Evaluation Criteria
When the Bradley Lake Power Plant was proposed a flurry of studies and assessment of resources at the
head of Kachemak Bay occurred to determine the impact that this project would have (Corps of
Engineers, 1982; FERC, 1985; USFWS, 1992). After the power plant was constructed an additional 5-year
study on the salmon at Bradley River was completed to compare the salmon populations before and
after construction. Since then there has been little effort to monitor salmon populations in this area. The
most recent formal study occurred in 2010 and 2011 on the salmon resources in Battle Creek (HDR,
2012).
It is agreed by CIAA that there is a lack of current information in these waterbodies at the head of
Kachemak Bay. This lack of activity is primarily driven by the resources available (time and money) in
relation to the importance of these returns to the fishery. The number of salmon returning to the
waterways in this area is low and contributes very little to the commercial fisheries. There is no
sustainable escapement goals set for any of these waterways of concern. Historical estimates have the
sockeye salmon population ranging at just over 2,000 fish for Fox River, 10Q-300 for Martin River and
10Q-300 for Bradley River.
In the study completed by Northern Ecological Services (1995) which summarized the 10-year salmon
study at Bradley River, they indicated that the sockeye salmon in the Bradley River showed a wide
variation in size and time of maturity suggesting that they may be strays from other systems. The most
recent study performed on Battle Creek in 2010 and 2011, also suggests that the sockeye salmon
distribution is limited and intermittent (HDR, 2012). Table 6 provides the "as the crow flies" distances
between the sample locations identified by ADFG. Considering the proximity of the other systems to
Bradley River and the fact that Bradley River's sockeye population may be strays, it is likely that these
