Book Description
"This operational plan provides the instruction and procedures to properly operate the Afognak Lake adult salmon escapement weir and successfully meet each project objective. The primary function of maintaining a weir at Afognak River is to enumerate sockeye salmon Oncorhynchus nerka returning to Afognak Lake for the Alaska Department of Fish and Game (ADF&G) management of the Afognak Bay commercial, subsistence, and sport fishery. All fish passing upstream or downstream through the weir are identified, enumerated, and reported to the ADF&G office in Kodiak daily. Enumeration at the weir serves a secondary purpose by providing run timing and escapement information for Kodiak Regional Aquaculture Association (KRAA), which uses Afognak Lake sockeye salmon as an early-run brood stock source for various enhancement projects on Kodiak Island. Project activities at Afognak River weir include installation, operation, and maintenance of the weir, salmonid enumeration, record daily physical weather observation, and the collection of age, sex, and length (ASL) samples and corresponding data."--Page 1

Book Description
"The Saltery Creek weir functions to enumerate sockeye salmon Oncorhynchus nerka returning to Saltery Lake for the Alaska Department of Fish and Game (ADF&G) management of the Ugak Bay commercial fishery. All fish passing up or down through the weir are identified, counted, and reported to the ADF&G office in Kodiak on a daily basis. Enumeration at the weir also provides run timing and escapement information for Kodiak Regional Aquaculture Association (KRAA), which uses Saltery sockeye salmon as a brood stock for the Spiridon Lake enhancement project (Kodiak Regional Planning Team 2011). Project responsibilities at Saltery Creek weir include installation, operation, weir maintenance, salmonid enumeration, daily physical weather observation, and age, sex, and length (ASL) sampling and data collection."--page 1

Book Description
The primary purspose of the sockeye slamon assessment project is to provide precise estimates of sockeye salmon total escapement into the Kanalku system, precise estimates of sockeye salmon spawning escapement at Kanalku Lake, and the mortality rate at the Kanalku Falls.

Book Description
The Alaska Department of Fish and Game (ADF&G) Division of Commercial Fisheries (CFD) staff will operate seven weirs and one fish pass in the Kodiak Management Area (KMA) in 2023–2025. These projects are located on the Karluk River, Ayakulik River, Dog Salmon Creek, Olga Creek (Upper Station), Afognak River (Litnik), Saltery Creek, and Pasagshak River. The weirs are used to enumerate salmon escapements into river systems and are critical management tools because they provide information that assists ADF&G management staff in deciding when to open and close salmon fisheries throughout the season. This operational plan informs seasonal employees of their responsibilities to run effective field camps, operate weirs, and live at remote sites. Operation dates for each weir vary depending upon the run timing of salmon populations into the different systems; however, most begin in mid to late May and continue through mid-September. Chinook Oncorhynchus tshawytscha, sockeye O. nerka, coho O. kisutch, pink O. gorbuscha, and chum salmon O. keta, as well as steelhead trout O. mykiss and Dolly Varden char Salvelinus malma, are individually counted by field crews. Escapement data collected provides the basis for inseason management actions regulating the commercial, sport, and subsistence fisheries in the KMA.

Book Description
The primary purpose of this project is to provide an estimate of the sockeye salmon escapement at McDonald Lake by conducting foot surveys on the spawning grounds at Hatchery Creek. We will also estimate the adult age composition of the escapement. Using results from a Pacific Salmon Treaty genetic stock identification project, we will estimate the contribution of McDonald Lake sockeye salmon to southern Southeast Alaska commercial net fisheries. This project also includes a fall hydroacoustic survey to estimate rearing juvenile sockeye salmon abundance.

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 (AS 16.05.730), follow appropriate principles and criteria in the Policy for the Management of Sustainable Salmon Fisheries (5 AAC 39.222), and achieve spawning escapement goals (5 AAC 39.223). 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 (Otis and Dickson 2002). 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 (Hollowell et al. 2022). 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 (Table 1; Otis et al. 2010, Otis et al. 2013, Otis et al. 2016).

Book Description
The goal of this project is to census the sockeye salmon escapement into Buskin Lake during 2022. The age, sex, and length composition of the run (escapement and subsistence harvest combined) to Buskin Lake will also be estimated.

Book Description
The Afognak Lake sockeye salmon, Oncorhynchus nerka, run severely declined in 2001. Concerns expressed by local subsistence users to the Alaska Dept. of Fish and Game and the U.S. Fish and Wildlife Service Office of Subsistence Management prompted an investigation of the lake's rearing environment in 2003 followed by subsequent annual studies. This report provides 2013 project results and an evaluation of limnology conditions and their effects upon smolt production.
