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.

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.

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 2016 Inriver Abundance and Run Timing of Kuskokwim River Chinook Salmon written by Nicholas James Smith and published by . This book was released on 2017 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A 2-sample mark-recapture experiment was conducted to estimate the abundance and upriver migration characteristics of adult Chinook salmon Oncorhynchus tshawytscha returning to the Kuskokwim River in 2016. Tagging occurred downriver from all known spawning tributaries, except the Eek River. A total of 621 Chinook salmon were marked with radio and spaghetti tags, of which 527 continued upriver migration and were used to estimate abundance. Radiotagged fish were tracked throughout the study area using a network of telemetry stations and a series of aerial telemetry surveys. Upriver escapement monitoring weirs served as 7 recapture locations, representing lower, middle, and upper river tributaries. A total of 21,590 Chinook salmon were evaluated for tags, and total tag recoveries was estimated at 94. Inriver abundance of Chinook salmon upstream of rkm 67 was 120,000 fish (95% CI: 99,304-147,502). Radiotagged Chinook salmon traveling to upriver tributaries were captured and tagged earlier in the run compared to tagged fish migrating to middle river tributaries. Chinook salmon returning to lower river tributaries were captured and tagged throughout the entire run. Chinook salmon swam at a median speed of 36 rkm/day (range: 31-41 rkm/day) through all portions of the mainstem Kuskokwim River upstream from Bethel.
Book Synopsis Operational Plan by : Nicholas A. Decovich
Download or read book Operational Plan written by Nicholas A. Decovich and published by . This book was released on 2020 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study is to estimate Chinook salmon (Oncorhynchus tshawytscha) abundance at river mile (RM) 34 of the mainstem Susitna River and spawning distribution among 5 Susitna River drainage management areas in 2020. A 2-event mark–recapture experiment in combination with radio telemetry will be used. Fish wheels and gillnets will be operated at RM34 to capture Chinook salmon for marking with dart-PIT tags (a dart tag with an imbedded passive integrated transponder [PIT]) and radiotelemetry tags. Recapture event sampling will occur at the Deshka River weir at RM 7 where a PIT detection array will be used. Eight radiotracking stations will be strategically placed throughout the drainage to determine when radiotagged fish move in and out of the 5 management zones. A concurrent genetics mark–recapture study will be performed using genetic samples taken from a systematic sample of all dart-PIT-tagged fish. The applied radio tags will also be used to estimate handling effects. In the event of a sport fishery, harvest sampling of axillary processes and genetic stock identification will be used to determine the proportions of non-Deshka River Chinook salmon stocks taken in 2 sections of the Deshka River.

Available in PDF, EPUB and Kindle. Book excerpt: A cooperative study involving the Department of Fisheries and Oceans Canada, the Alaska Department of Fish and Game, and the Taku River Tlingit First Nation was conducted to estimate the number of spawning Chinook salmon Oncorhynchus tshawytscha in the Taku River in 2003 with a mark-recapture experiment. Fish were captured at Canyon Island on the lower Taku River with fish wheels from May through August and were individually marked with back-sewn, solid-core spaghetti tags. All tagged fish were also batch marked with an opercle punch plus removal of the left axillary appendage. Sampling on the spawning grounds in tributaries was used to estimate the fraction of the population that had been marked. The estimated spawning abundance of small Chinook salmon ( 400 mm long; mid-eye to fork of tail) was 3,489 (SE = 1,052). Spawning abundance of medium-size Chinook salmon (401-659 mm) was estimated to be 16,780 (SE = 2,274). Finally, spawning abundance of large-size fish (= 660 mm) was estimated to be 36,435 (SE = 6,705), and the estimated total of all fish was 56,704 (SE = 7,158). The sum of the peak aerial survey counts of large spawning Chinook salmon conducted at five index tributaries of the Taku River was 16% of the mark-recapture estimate. Age 1.3 fish (1998 brood year) constituted an estimated 40% of the spawning population, followed by age 1.2 fish (1999 brood year), which constituted an estimated 29% of the population
