Book Description
This project will survey the coho salmon sport fishery on the Naknek River in 2023 to estimate angler-days of effort by type of angler (guided vs. unguided), catch and harvest rates of coho salmon, as well as sex, length, and weight of coho salmon in the sport harvest. Data collected from onsite surveys will be used to document angler use patterns and to design regulations that will accommodate growth in the sport fishery and maintain angling opportunity. Results will also guide review of current regulations and will be used to assess the effectiveness of current regulations.

Book Description
This project surveys the Chinook salmon sport fishery on the Nushagak River. Information will be collected on angler-days of effort by type of angler (guided vs. unguided) and gear (bait or no bait), catch and harvest rates of Chinook salmon, as well as age, sex, length, weight, and genetics of Chinook salmon in the sport harvest. Data will be reported to fisheries managers in Dillingham daily, providing real-time information regarding sport fishing success as well as the composition of the harvest. Data collected from onsite surveys will be used to document use patterns and design regulations that will accommodate growth of the sport fishery and maintain angling opportunity. Results will also guide review of current regulations and will be used to assess the effectiveness of current regulations in maintaining compliance with the management plan.

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
"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
A creel survey will be conducted to estimate sport angler effort, catch, and harvest of large (≥75 cm mid eye to tail fork length) early- and late-run Chinook salmon in the lower Kenai River between the Warren Ames Bridge (river mile [RM] 5.1) and Slikok Creek sanctuary area (RM 18.6). Creel survey estimates will be geographically stratified in relation to the RM 13.7 Kenai River Chinook salmon sonar to provide angler effort, catch, and harvest of large Chinook salmon. A standardized inriver netting project will be conducted in the Kenai River at RM 8.6 to index abundance and estimate the age, sex, and length (ASL) composition of large early- and late-run Chinook salmon. Inseason estimates of Chinook salmon catch and harvest, used in conjunction with sonar passage estimates, inseason catch rates, and the length of returning Chinook salmon from the inriver netting study are used by fisheries managers for inseason management decisions to achieve escapement goals. This plan covers the creel survey and inriver netting studies for the 2021–2023 seasons.

Book Description
This study will describe the geographic spawning distribution of radiotagged coho salmon in the Kenai River drainage for 2 years (2023 and 2024). Drift gillnets will be employed in the Kenai River to capture and tag adult coho salmon with radio transmitters. Radiotelemetry will be used to uniquely identify and track tagged coho salmon to spawning destinations. Up to 490 radio transmitters will be deployed annually between August 1 and October 31 each year. Movements of radiotagged coho salmon will be documented using a combination of fixed data-logging receiver stations and mobile tracking using boats and fixed-wing aircraft. This project will be the 2nd and 3rd year of a 3-year collaboration between the Alaska Department of Fish and Game (ADF&G) and the U.S. Fish and Wildlife Service (USFWS). The USFWS conducted the first year of the project in 2022, and ADF&G and USFWS will be collaborating on the radiotelemetry project in 2023 and 2024.

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
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.
