This book was released on 2016 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted from 2012 to 2014 to assess the feasibility of using sonar, in combination with gillnetting and a fish wheel, to estimate salmon abundance in the Tanana River. Eight sites between Cosna Bluff and the confluence of the Kantishna and Tanana rivers were surveyed, bottom profiles were analyzed for suitability of sonar operation, and a site near Manley Hot Springs was selected. Split-beam sonar was operated on the left bank, and imaging sonar on the right bank. Drift and set gillnets were used to apportion the left bank sonar estimates, and drift gillnets and a fish wheel were used to apportion the right bank sonar estimates. Both sonar and test fishing methods were modified and assessed for effectiveness throughout both seasons. The sonars were found to provide effective coverage with 95% of fish passing within 80 m of the transducer on the left bank, and within 16 m on the right bank. The drift gillnets and fish wheel proved to be effective fishing methods, though refinement of these methods should be a goal in future seasons. Based on the information obtained, estimating salmon abundance in the Tanana River using sonar, with drift gillnets and a fish wheel used for species apportionment is feasible.
Download or read book Estimating Adult Chinook Salmon Abundance on the Chilkat and Unuk Rivers Using Transgenerational Genetic Mark recapture written by Randy L. Peterson and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transgenerational genetic mark–recapture (tGMR) methods will be used to estimate the spawning abundance of Chinook salmon Oncorhynchus tshawytscha at the Chilkat and Unuk Rivers in 2020 and 2021, respectively. Tissue samples from adults returning to the Chilkat River were collected in the summer of 2020 and from parr rearing in the Chilkat River in the fall of 2021. Lab work and data analysis will be completed in the winter of 2021–2022. Similarly, tissue samples from adults returning to the Unuk River were collected in the summer of 2021, and samples will be collected from parr in the fall of 2022. Lab work and data analysis will be completed in the winter of 2022–2023. These studies will be used to determine the feasibility of using tGMR to estimate escapement in Southeast Alaska by comparing tGMR abundance estimates to abundance estimates generated through existing field programs. This operational plan covers the lab and project reporting aspects of these projects. Primary data collection activities are described in the project-specific operational plans.

Download or read book Mark recapture Abundance Estimates for Yukon River Chinook Salmon in 2003 written by Ted R. Spencer and published by . This book was released on 2006 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abundance of adult Chinook salmon Oncorhynchus tshawytscha passing by the village of Russian Mission was estimated in 2003 as part of a radio telemetry study on the Yukon River. Drift gillnets were used to capture 2,312 salmon at Russian Mission, 1,097 of which were marked with plastic spaghetti tags and esophageal radio transmitters. Marked fish were tracked upstream to spawning grounds. Chapman's modification of Petersen's closed-population, two-event mark-recapture experiment was used to estimate abundance. The second sampling event consisted of salmon spawning in select locations or caught in select fisheries representing populations that returned early (bound for Canada), late (bound for the Koyukuk River), and mid-run (bound for the Tanana River). Of the 36,032 large salmon (= 650 mm METF) involved in the second event, 146 carried transmitters for an estimated abundance of 261,545 chinook salmon. Diagnostic testing showed this estimate to be consistent. Bootstrap simulation was used to estimate the variance (SE=18,911).
Download or read book Escapement Estimation Spawner recruit Analysis and Escapement Goal Recommendation for Fall Chum Salmon in the Yukon River Drainage written by Steven J. Fleischman and published by . This book was released on 2009 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical escapement and run size of fall chum salmon Oncorhynchus keta was reconstructed from incomplete sonar, weir, counting tower, mark-recapture, aerial survey, and foot survey data of varying precision from 1974 to 2007. The resulting estimates of drainage-wide escapement were fitted to an age-structured Ricker spawner-recruit model. Bayesian statistical methods were employed, which allowed for realistic assessment of uncertainty in the presence of measurement error, serial correlation, and missing data.
