Book Description
Aerial index counts from 22 NCIMA Chinook salmon streams are used detect trends in escapement for various NCIMA stocks and are used to assist fisheries managers with future management and refinement of escapement goals for streams and stocks. The objectives of this project are to count the number of Chinook salmon in each of 22 selected NCIMA area streams during 1 annual survey of each stream between 15 July and 7 August in 2021 through 2025, and to count the number of coho salmon in each of 8 selected NCIMA area streams during 1 annual survey of each stream between 20 September and 4 October in 2021 through 2025. Surveys may be limited by budgetary constraints and priority will be given to streams and stocks with escapement goals.

Book Description
The Deshka River is the largest producer and has the largest sport fishery of Chinook salmon in the North Cook Inlet Management Area. The Deshka River weir has operated seasonally since 1995. A floating, resistance-board-weir is used at river mile (RM) 7 to enumerate Chinook and coho salmon and to collect age, sex, and length data from these species. The Deshka River sustainable escapement goal (SEG) range is currently 9,000–18,000 fish for Chinook salmon and 10,200–24,100 fish for coho salmon. Data collected at this weir are used to manage sport and commercial fisheries inseason and to develop and evaluate escapement goals. This project is also used as a platform to collect harvest data upstream of RM 7, passage data of other fish species, environmental data, and it provides recapture data for the greater Susitna River drainage Chinook salmon mark–recapture project.

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
This operational plan details the qualitative evaluation of Chinook and coho salmon stocks in selected drainages within the Anchorage Management Area. The numbers of Chinook salmon and coho salmon will be counted in 5 different drainages by foot and float surveys. The numbers of other salmon species will be recorded as well. Data from these surveys will be used to manage the Chinook and coho salmon sport fisheries in the Anchorage Management Area.

Book Description
The Deshka River is one of the Northern Cook Inlet Management Area's most popular fishing locations. This project's purpose is, to: 1) monitor the Chinook and coho salmon escapement for inseason management decisions; 2) determine the relative accuracy and consistency of the single aerial survey for Chinook salmon and the actual weir count: 3) to collect unbiased Chinook salmon age data to be used in the development of spawner-recruit and sibling relationship models. Additionally in 2013 and 2014 a mark-recapture estimates of Susitna River drainage Chinook and coho salmon abundance will be made using the escapement past the weir at Deshka as one of the recapture locations.

Book Description
This project will assess weir passage and age and sex structure of Chinook and coho salmon runs in the Little Susitna River. The information collected during this project will allow for inseason management of these runs and provide long-term data for escapement goal analysis. A resistance-board weir will be operated at river mile 32.5 of the Little Susitna River to count Chinook and coho salmon, as well as other species present. A subset of Chinook and coho salmon passing the weir will be trapped and sampled for sex, length, and age (Chinook salmon only) data. Water level, temperature, and clarity, number of boats passing, and angler interviews will also be recorded.

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
Thermal marks and adipose finclips will be applied to hatchery-produced Chinook salmon smolt released at Ninilchik River and Crooked Creek. Thermal marks will also be applied to hatchery-produced Chinook salmon released in Cook Inlet, Prince William Sound, and Resurrection Bay as well as to hatchery-produced coho salmon smolt released in Cook Inlet and Resurrection Bay. This project will be used to support other projects designed to evaluate the contribution of these hatchery-produced fish to sport fisheries and spawning escapements. Adipose finclips will also aid in the selection of naturally-produced Chinook salmon for broodstock, which will be used to produce progeny for release at Ninilchik River and Crooked Creek. Thermal marks may be used to monitor straying at broodstock collection sites.

Book Description
This project will enumerate coho salmon (Oncorhynchus kisutch) and other fish passage at a floating resistance-board weir in the Jim Creek drainage during 2023–2027. The number of adult coho and sockeye salmon that pass through the weir from 20 July to 30 September will be counted and estimates of sex composition for adult coho salmon and age and sex composition of adult sockeye salmon will be made for both years.
