Book excerpt: The Skeena River, located in north coastal British Columbia, is the second largest salmon producing watershed in the province. Concerns have been expressed for the stock status of early run Skeena River coho salmon because of declining escapement levels. Available data on spawning escapements and subsequent recruitment were analyzed using a Ricker model under various assumptions about fishery interception rates to derive maximum sustainable yield escapement levels. The analysis used a test fishing index, collected consistently since 1956, to derive the escapement to the river-mouth, rather than the usual visual observations made on the spawning grounds.

Book excerpt: In 2020-2024, Chinook salmon (Oncorhynchus tshawytscha) will be enumerated at 2 Anchor River sites from mid-May through early August to monitor escapement for the drainage. The south fork site, located at approximately river kilometer (RKM) 4.0, will be monitored by an Adaptive Resolution Imaging Sonar (ARIS) during high flow periods, and a resistance board weir fitted with underwater video will be used thereafter. The north fork site, located at about RKM 5.3, will be monitored by a resistance board weir with underwater video from the beginning of the Chinook salmon run in early May. Motion-detection technology will be used at each weir to record fish passage 24 hours per day. Weekly beach seine surveys will be used to capture Chinook salmon for age-sex-length (ASL) samples downstream of the confluence of the south and north forks. Chinook salmon data will be used to update estimates of the spawner-recruit relationship and harvest rate, and to provide inseason run information to managers. Coho salmon and steelhead will also be monitored in the fall of each year using the resistance board weir and video system on each fork. Coho salmon age, sex, and length will be collected via beach seining. Coho salmon escapement and harvest rate will be estimated along with an index of steelhead abundance and catch rate.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A weir will be used on the Buskin River to count the inriver coho salmon run, with harvest estimated by the Alaska Department of Fish and Game statewide harvest survey, returned subsistence permits, and commercial fish tickets. Age and sex information will be collected from the Buskin River coho salmon run, and the composition of the run by age and sex will be estimated. In addition, coho salmon escapements to 9 other drainages on the Kodiak road system (KRS) will also be indexed. Sustainable escapement goals (SEGs) associated with the American, Olds, and Pasagshak Rivers will be monitored via postseason escapement foot surveys. A simultaneous postseason drone survey will also be conducted on the American and Olds Rivers to continue exploring establishment of drone-based SEGs. Multiple inseason surveys will be conducted by drone at each of the Olds, American, and Pasagshak river drainages to provide inseason run information to fishery managers; the inseason data will also be used to explore new ways of establishing SEGs for the Pasagshak River. Postseason escapement foot surveys will be conducted for the remaining 6 KRS rivers without SEGs (Monashka Creek, Pillar Creek, Sargent Creek, Russian Creek, Salonie Creek, and Roslyn River). The Pasagshak River coho salmon escapement will also be estimated with a temporally stratified mark–recapture study.
