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
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
The Crooked Creek Chinook Salmon Enhancement Project is designed to monitor both naturally- and hatchery-produced Chinook salmon (Oncorhynchus tshawytscha) escapement as well as collect broodstock and conduct egg takes to provide additional sport fishing opportunities within the Kasilof River and other terminal fisheries on the Kenai Peninsula. This project will imprint Chinook salmon smolt for 7 to 10 days at the beginning of June. Additionally, age, sex, and length, will be collected from returning naturally- and hatchery-produced Chinook salmon. The sustainable escapement goal for Crooked Creek is 700–1,400 naturally-produced Chinook salmon.

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 project surveys the Chinook salmon sport fishery on the Naknek River. Information will be collected on angler-days of effort by type of angler (guided vs. unguided), catch and harvest rates of Chinook salmon, as well as age (from scales), sex, length, and weight of Chinook 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
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
The purpose of this project is to determine Chinook salmon Oncorhynchus tshawytscha harvest by sport anglers on the Situk River and the age components of that harvest. Additionally, sockeye salmon Oncorhynchus nerka harvest will be determined and various methods of angler use patterns for both species will be recorded. Creel sampling techniques will be used to collect catch, harvest, effort and biological information from the Situk River for this purpose. This information is used to manage for the Chinook salmon biological escapement goal for the Situk River as per the Situk-Ahrnklin and Lost River Chinook salmon Management Plan, along with achieving the Situk River sockeye salmon biological escapement goal. Inriver abundance for both Situk River Chinook and sockeye is obtained from another project with a fish weir, and escapement is calculated by subtracting the above-weir sport harvest estimate of this project from that weir count. Additionally, the Chinook salmon age component information of the harvest gathered here is required for yearly stock assessment models to predict the following years run and set preseason management regulations.

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
Sport anglers fishing from shore in the Juneau area of Southeast Alaska target and harvest Chinook salmon Oncorhynchus tshawytscha, primarily during April – August, the duration of which can be truncated due to wild stock management measures. Angler effort, catch, and harvest data will be collected from June through August 2023 from shore-based anglers at 2 prioritized locations in the Juneau area associated with Alaska hatchery release sites. Harvest sampling will be used to collect biological samples and associated data to estimate the age, length, and genetic composition of the Chinook salmon harvest. Chinook salmon will be inspected for missing adipose fins, indicating the head should be removed to recover a coded wire tag.

Book Description
A brief overview of the chinook and salmon fisheries in the Nushagak River and their management begins this document. The remainder describes a research plan for a study that will take place in 2006 at the river using radio tag detection in order to identify major spawning tributaries, estimate the proportion of spawning salmon in those tributaries, describe stock-specific run-timing patterns, and estimate system-wide abundance of sockeye salmon returning to the Nushagak River. The software to be used is Telemetry Manager produced by LGL.
