This plan must organize and guide the hatchery’s operations, for each calendar year, regarding production goals, broodstock development, and harvest management of hatchery returns. Egg take through release details are included in planning for succeeding calendar years. In-season assessments and project alterations by Cook Inlet Aquaculture Association (CIAA) or Alaska Department of Fish and Game (ADF&G) may result in changes to this AMP in order to reach or maintain program objectives. CIAA will notify the ADF&G private nonprofit (PNP) hatchery program coordinator in a timely manner of any departure from the AMP. The ADF&G PNP coordinator will advise as to whether an amendment, exception report, or other action is warranted. No variation or deviation will be implemented until an AMP amendment has been approved or waived by both the department and CIAA. This policy applies to all hatchery operations covered under the AMP. 1.2 New This Year: (production, harvest management, culture techniques, etc.) 1.2.1 Facility Changes There are no changes to the facility planned for 2020. 2020 Trail Lakes Hatchery Annual Management Plan 1.2.2 Production Changes • Bear Lake Sockeye Salmon o Due to BY2018 broodstock availability resulting in egg shortage the 2020 smolt program will be not be completed as all progeny were released as fry in 2019. • English Bay Lakes Sockeye Salmon (Second Lake) o CIAA is not planning to collect eggs from the English Bay Lakes system. • Hidden Lake Sockeye Salmon* o Based on the 4-year floating averages and in order to maintain adult returns at 30,000 and hatchery capacity limitations, the egg-take goal for brood year 2020 (BY20) will be 1,266,000 o 2020 Goals*: BY20 Brood: 1,116 fish total (558 female; 558 male) BY20 Egg-take Goal: 1,266,000 green eggs BY20 Stocking Goal: 1,101,000 unfed fry to Hidden Lake Note* Calculations based off 2012-2017 Operational plan, extended to 2018. To be updated with 2019-2023 five-year operational plan Hidden Lake Sockeye Program, anticipated approval 2020 o CIAA estimates 1,100,800 unfed fry will be stocked in 2020. • Shell Lake Sockeye Salmon o CIAA is expecting little adult sockeye salmon returns from the BY16 sockeye smolt stocking effort and little to no natural returns are expected. CIAA will monitor the sockeye return. If adequate fish are available broodstock and gametes will be collected for rearing to smolt and release back into Shell Lake. CIAA and ADF&G have discussed using hatchery returns as future broodstock. While the genetic policy does not promote the use of hatchery returns as a broodstock source, there is agreement that Shell Lake warrants an exception. • Lower Cook Inlet Lakes Sockeye Salmon (EBL stock) o No production changes. • Bear Lake Coho Salmon o CIAA may keep fry in excess of the 450,000 fry stocking goal to rear to the smolt stage for release to Bear Creek. 1.2.3 Fish Culture Changes o Until an alternative site for the LCI Sockeye program is located, for the eggs allocated to terminal fisheries (Hazel, Leisure, and Kirschner lakes), the mating cross will be 2 females to 1 male. This will reduce the number of fish required for broodstock and 2 2020 Trail Lakes Hatchery Annual Management Plan reduced the density in the lensing bag. For the eggs allocated to Tutka smolt production the mating cross will be 1 female:1 male as these fish will be used for future broodstock. o CIAA will administer Draxxin to adult female sockeye salmon broodstock returning to Bear Creek Weir. Approved drug prescribed via licensed veterinarian. 1.2.4 Evaluation Changes • Hidden Lake Sockeye Salmon o Pending discussions with USFWS, CIAA is not planning to perform any straying analysis outside of Hidden Lake. CIAA sampled outside of Hidden Lake for the last 3 years and no strays were found. This fulfilled the sampling requirements of the Hidden Lake Operational Plan. o Otoliths will be collected in Hidden Lake to assess spawning fidelity. • Shell Lake Sockeye Salmon o CIAA will operate a smolt trap in Shell Creek to estimate the smolt outmigration from Shell Lake in 2020. o CIAA will install a video camera in Shell Creek to enumerate the adult salmon return to Shell Lake. 1.2.5 Projected Return and Cost-recovery (CR) Licensing Changes • Hidden Lake Sockeye Salmon o No change. • Bear Lake/Kachemak and Kamishak Sockeye Salmon o To meet the 2020 cost recovery goal, CIAA anticipates a significant cost recovery harvest in Resurrection Bay/Bear Lake. • Tutka Bay Sockeye Salmon o No change. • Port Graham Bay Sockeye Salmon o No sockeye salmon adults are expected to return in 2020. 1.3 Fish Transport Permits (FTPs) or Amendments Needed This Year TLH FTPs amendments needed in 2020, to extend the effective period are: • 15A–0069 for the transfer of English Bay Lake stock adult sockeye salmon from Tutka Bay Lagoon to hold in lensing bag or similar containment structure located in Port Graham for maturation and egg take to avoid water demand conflicts with pink salmon. • 15A–0077 for the collection of up to 2,500 adult sockeye salmon from Kirschner Lake for broodstock purposes. New TLH FTPs needed in 2020 are: No new FTPs are required. 3 2020 Trail Lakes Hatchery Annual Management Plan 1.4 Expected Return The following assumptions are used to estimate the number of eggs to be collected in 2020.
