Book Description
The goals of this study are to estimate the participation and harvest of 5 personal use salmon fisheries that occur in Upper Cook Inlet. Harvests of sockeye (Oncorhynchus nerka) and Chinook (O. tshawytscha) salmon will be estimated from the Kasilof gillnet fishery; harvests of sockeye, coho (O. kisutch), and pink (O. gorbuscha) salmon will be estimated from the Kasilof dipnet fishery; harvests of sockeye, Chinook, coho, and pink salmon will be estimated from the Kenai dipnet fishery; and harvest of sockeye and coho salmon will be estimated from the Fish Creek and Susitna River dipnet fisheries. Incidental harvest of flounder will also be estimated for all for fisheries.

Book Description
To facilitate informed inseason management of commercial fisheries targeting Pacific salmon Oncorhynchus spp., the Alaska Department of Fish and Game (ADF&G) uses aerial and ground survey methods to monitor escapement on select index streams in Lower Cook Inlet (LCI). Surveyors make periodic counts of sockeye O. nerka, chum O. keta, and pink O. gorbuscha salmon throughout the duration of their respective runs. Fishery managers use these data daily to manipulate time and area fishery openings/closures in an effort to assure that the final escapement level for monitored stocks falls within their individual escapement goal ranges. At the end of the season, periodic aerial and ground survey counts are used to calculate a final escapement index for each stream based on the area-under-the-curve method (pink and chum salmon) or the peak survey count (sockeye salmon). This report provides operational guidelines for aerial and ground survey-based monitoring of salmon escapements in LCI.

Book Description
Age, sex, and length composition information will be collected from harvested Chinook salmon in the Upper Cook Inlet Eastside set gillnet (ESSN) commercial fishery in 2021–2023. Genetic tissues from the harvest will also be collected and archived for potential future mixed stock analysis. The primary goal of the study is to estimate the age, sex, and length composition of the Chinook salmon harvest and to estimate the harvest of large (>75 cm METF) Kenai River Chinook salmon in the ESSN fishery for each season (2021–2023). Age, sex, and length composition will be estimated for each temporal and geographic stratum and for each season. The harvest of large Kenai River Chinook salmon will be estimated using historical (2010–2020) large fish stock compositions relative to the total large fish harvest for each temporal and geographic stratum and summed to the total for each season.

Book Description
The Lower Cook Inlet Management Area consists of all coastal waters and inland drainages entering waters north of Cape Douglas, west of Cape Fairfield, and south of Anchor Point. In 2022, commercial harvest was approximately 751 thousand salmon and was composed of 403,035 pink Oncorhynchus gorbuscha, 292,845 sockeye O. nerka, 53,793 chum O. keta, 1,000 coho O. kisutch, and 275 Chinook salmon O. tshawytscha. Approximately 74.4% of the harvest (555,953 salmon) was sold as common property harvest, and 191,169 salmon were sold for hatchery cost recovery, including carcass sales. Homepack and donated fish (3,826 salmon) accounted for less than 1% of the harvest. Based on fish ticket reporting, the preliminary value of the commercial salmon harvest was $3.7 million, including hatchery sales. During the 2022 season, 15 set gillnet and 11 purse seine permit holders reported commercial deliveries. An additional 3 set gillnet permit holders harvested salmon as home pack and did not report any commercial deliveries. Set gillnet harvest value was an estimated $333,816, with average permit earnings of $22,254. Purse seine fishery exvessel harvest value was an estimated $2.1 million, with average permit earnings of $187,868. Revenue generated by cost recovery for hatchery operations was approximately $1.3 million. A total of 1,531 salmon were harvested in the Kachemak Bay personal use set gillnet fishery.

Book Description
The overall purpose of this project is to provide information on the run-timing and magnitude of Pacific salmon Oncorhynchus spp. escapements to Red Lake in the Southern District of the Lower Cook Inlet Management Area (LCIMA). Results will be used by Alaska Department of Fish and Game (ADF&G) and Alaska Energy Authority (AEA) staff to evaluate the extent to which salmon access and use Red Lake. This project is 1 component of the AEA’s preliminary assessment of fishery resources in the Martin River drainage, which is under consideration for future hydroelectric power development. This plan documents procedures developed for estimating salmon escapement using unmanned, or autonomous video counting towers (AVCT) that employ above-stream remote video cameras and digital time-lapse recording equipment (Otis and Dickson 2002, Otis 2020). Hard drives will be retrieved monthly, and video reviewed to enumerate daily escapement for all species identified passing the video site.

Book Description
The overall purpose of this project is to provide information on the run-timing and magnitude of sockeye salmon Oncorhynchus nerka escapements to Mikfik and Chenik lakes in the Kamishak District of the Lower Cook Inlet Management Area (LCIMA). Results will be used by Alaska Department of Fish and Game (ADF&G) fisheries managers to facilitate informed inseason management of commercial purse seine fisheries targeting these stocks to be consistent with sustained yield of wild stocks, follow appropriate principles and criteria in the Policy for the Management of Sustainable Salmon Fisheries, and achieve spawning escapement goals. This plan documents procedures we developed for estimating sockeye salmon escapement using an unmanned, or autonomous video counting tower (AVCT) that employs above-stream remote video cameras and digital time-lapse recording equipment. Hard drives are retrieved regularly, and video reviewed immediately so managers can use these data to adjust fishery openings in season to attain established escapement goals. The annual escapement indices derived by remote video are also used to refine the sustainable escapement goals for these stocks, currently established by ADF&G at 3,400-11,000 for Mikfik Lake and 2,900-13,700 for Chenik Lake.
