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).
Book Synopsis Estimation of Abundance and Distribution of Chinook Salmon in the Yukon River Using Mark-recapture and Radio Telemetry in 2000 and 2001 by : Ted R. Spencer
Download or read book Estimation of Abundance and Distribution of Chinook Salmon in the Yukon River Using Mark-recapture and Radio Telemetry in 2000 and 2001 written by Ted R. Spencer and published by . This book was released on 2003 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this multi-year (1999-2002) cooperative study between the Alaska Department of Fish and Game and the National Marine Fisheries Service was to determine the migratory characteristics and escapement distribution of Yukon River chinook salmon. Primary objectives in 2000 and 2001 were to assess and refine fish capture and radio-tracking methods for a full-scale program in 2002, and to estimate drainage-wide population size using mark-recapture techniques.
Book Synopsis Estimation of the Abundance of Chinook Salmon, Oncorhynchus Tshawytscha, in the Upper Yukon River Basin Using Mark-recapture Methods, 1990-95 by :
Download or read book Estimation of the Abundance of Chinook Salmon, Oncorhynchus Tshawytscha, in the Upper Yukon River Basin Using Mark-recapture Methods, 1990-95 written by and published by . This book was released on 2002 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries & Oceans Canada has conducted mark-recapture studies on adult Yukon River chinook salmon since 1982. In some of these studies, up to 2,174 upstream migrants were spaghetti tagged annually at two fishwheels located just upstream from the Canada/US border. Recaptures were made in a commercial fishery upstream. This report presents results from the chinook mark-recapture program for 1990 to 1995. Background on the Yukon River, its chinook population & fishery, and mark-recapture & data analysis methods begins the report. Results are presented with regard to the biological characteristics of salmon captured, abundance estimates using three estimation methods, fishery catches & spawning escapement, harvest rates, and migration rates. The final section discusses problems with respect to the abundance estimators used and makes recommendations for further research.

Book Synopsis Estimating Adult Chinook Salmon Abundance on the Chilkat and Unuk Rivers Using Transgenerational Genetic Mark–recapture by : Randy L. Peterson
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.
