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.

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. Contributions of hatchery and wild coded-wire-tagged stocks to the sport harvest will be estimated for both locations.

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 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
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
Sport-angler effort and harvest of Chinook salmon Oncorhynchus tshawytscha were estimated from a creel survey conducted at 2 distinct hatchery release sites along the Juneau shoreside from 1 June to 28 August 2022. This time period aligned with liberalized sport bag and possession limits targeting Alaska hatchery Chinook salmon production at a designated sport harvest hatchery area encompassing these 2 hatchery release sites as well as adjacent marine waters. Sport anglers harvested an estimated total of 2,628 Chinook salmon across both hatchery release areas, including 1,462 (SE = 207) at Macaulay Salmon Hatchery and 1,165 (SE = 259) at Fish Creek. The total Chinook salmon harvest observed at Macaulay Salmon Hatchery (1,462) included 1,383 (SE = 207) large and 80 (SE = 80) non-large fish. The total Chinook salmon harvest observed at Fish Creek (1,165) included 982 (SE = 221) large and 183 (SE = 55) non-large fish. Total effort (angler-hours) was estimated at 18,905, including 12,623 (SE = 629) at Macaulay and 6,282 (SE = 481) at Fish Creek. The stock composition based on genetic analysis revealed Chinook salmon harvested in these 2 distinct hatchery release areas were approximately 99% enhanced-origin fish from the Andrew Creek stock. Large Chinook salmon (defined as fish >28ʺ total length) dominated the total catch across both areas (approximately 84%). The age composition of large Chinook salmon harvested by sport anglers across both areas was dominated by age-1.3 fish (>80%). Residents comprised about 65% of all interviewed anglers.

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
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.
