Book Synopsis Situk River Chinook and Sockeye Salmon Sport Harvest Estimates, 2008-2011 by : Brian Marston
Download or read book Situk River Chinook and Sockeye Salmon Sport Harvest Estimates, 2008-2011 written by Brian Marston and published by . This book was released on 2016 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the years 2008-2011, sport angling effort, catch, and harvest was estimated on the Situk River using creel sampling interviews. This sampling was targeted at anglers fishing for Chinook salmon Oncorhynchus tshawytscha and sockeye salmon Oncorhynchus nerka on the Situk River from June 9 through July 31 each year. The methodology used in this report, and in past reports, utilized one sampler at a primary angler exit point on a lower portion of the river, and analysis with a mathematical expansion factor to expand that estimation and calculate fishery statistics for the entire drainage. In the last two years of this project period (2010 and 2011) a new method was also used that sampled all the exit points on the river with a second sampler in an attempt to improve precision. Chinook salmon fisheries were curtailed or closed on the Situk River by management actions all years of this report due to low abundance; during the same time, sockeye salmon abundance was high, and regulations were liberalized all years, except in 2008. Angler effort, measured in the number of hours fished, ranged from 8,782 to 10,701 hours per year. Foot traffic was the most common technique used by anglers, and jet boat travel was the least. Non-resident angler hours outnumbered resident angler hours. Non-guided angling effort was far more common than guided angling. The total number of Chinook salmon of all sizes caught ranged from 10 to 149, and the number harvested from zero to 64. Sockeye salmon catch ranged from 5,348 to 6,964 fish, and sockeye harvest ranged from 3,376 to 4,411 fish. In 2010 and 2011 the new sampling methodology estimated fishery performances with similar trends, but with lower estimates than the method used previously.

Book Synopsis Operational Plan: Situk River Chinook Salmon Creel Survey, 2020 by : Jason A. Pawluk
Download or read book Operational Plan: Situk River Chinook Salmon Creel Survey, 2020 written by Jason A. Pawluk and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Production and Harvest of Chilkat River Chinook and Coho Salmon, 2019-2020 by : Brian W. Elliott
Download or read book Production and Harvest of Chilkat River Chinook and Coho Salmon, 2019-2020 written by Brian W. Elliott and published by . This book was released on 2020 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ongoing coded-wire tag project, used as part of a stock assessment program for Chilkat River Chinook salmon Oncorhynchus tshawytscha and coho salmon Oncorhynchus kisutch, will be conducted during fall 2019 and spring 2020 to provide estimates of smolt abundance and marine harvest for Chinook and coho salmon. This project uses modified Peterson 2-event mark-recapture methods to estimate smolt abundance, and port and creel sampling of coded-wire tags in mixed stock commercial and sport fisheries to estimate marine harvest for both species. Juvenile salmon will be measured for length and weight, marked with adipose fin clips, and tagged with coded wire tags in fall 2019 (juvenile Chinook salmon) and spring 2020 (Chinook and coho salmon smolt) as event 1 of the mark-recapture study. During event 2, adult Chinook salmon will be sampled for missing adipose fins, coded wire tags, age, sex, and length in Chilkat River fishwheels and drift gillnets, which are operated in the lower Chilkat River as part of a separate adult mark-recapture project. Adult Chinook salmon will be also sampled for missing adipose fins, coded wire tags, and age, sex, and length during Chilkat River drainage spawning grounds surveys to complete event 2 sampling. Coho salmon will also be sampled as adults during event 2 in the lower Chilkat River fishwheels. Age composition of Chinook salmon adults will be estimated by scale ageing techniques; age composition of coho salmon smolt and adults will also be estimated. The Alaska Department of Fish and Game uses these data to make local and regional management decisions. Chilkat Chinook salmon is a Pacific Salmon Commission exploitation rate and escapement indicator stock and has recently been added to the base model of abundance indicator stocks for the Chinook Technical Committee, which influences coastwide management

Available in PDF, EPUB and Kindle. Book excerpt: During 1999 and 2000 naturally-produced and hatchery-produced chinook salmon, Oncorhynchus tshawytscha, returns to the Ninilchik River were assessed with a weir to determine the age and sex compositions of total escapements and to estimate the contribution of chinook salmon that stray to the Ninilchik River from three Kachemak Bay chinook salmon enhancement locations. Additionally during 2000, a random sample of sport harvested Chinook salmon were examined for an adipose finclip to estimate the stock composition of the harvest sampled each weekend in the Ninilchik River below the Sterling Highway. This report examines the results of these studies.
