Book Synopsis Southeast Alaska Coho Stock Assessment, 2022-2024 by : Justin T. Priest
Download or read book Southeast Alaska Coho Stock Assessment, 2022-2024 written by Justin T. Priest and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This project provides stock assessment information for Southeast Alaska coho salmon (Oncorhynchus kisutch) indicator stocks at Berners River and Hugh Smith Lake. Coho salmon smolt at the Berners River and Hugh Smith Lake are captured, implanted with a coded wire tag (CWT), sampled for age and length, adipose fin clipped, and released unharmed. Concurrent to smolt tagging, a project to collect scales of a known age requires capturing and implanting a CWT into coho salmon fry, later to be recovered as smolt and adults. Returning adult coho salmon are examined for the presence of CWTs, enumerated, and sampled for age, length, and sex. These data are used in combination with estimates of harvest of tagged fish by Alaska Department of Fish and Game port sampling and Mark, Tag and Age Laboratory programs to estimate a variety of parameters for the stocks. These programs, conducted continuously since the 1980s, provide detailed information on long-term population dynamics useful for establishing escapement goals and for managing commercial fisheries that target coho salmon."--Page 1
Book Synopsis Production and Escapement of Coho Salmon from the Chilkat River, 2004-2005 by : Randolph P. Ericksen

This book was released on 2006 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to conduct a full stock assessment of Chilkat River coho salmon, Oncorhynchus kisutch. Coho salmon smolt were captured in the Chilkat River during spring 2004, marked with an adipose fin clip and a coded wire tag (CWT), and sampled for age, weight, and length. In 2005, adult coho salmon were sampled for CWTs in recreational and commercial fisheries harvests throughout southeast Alaska, and in the Chilkat River to determine the marked fraction. In addition, the escapement of adult coho salmon to the Chilkat River in 2005 was estimated by a mark-recapture experiment.

Book Synopsis A Comprehensive Review of Chilkat Lake and River Sockeye Salmon Stock Assessment Studies by : Julie Bednarski
Download or read book A Comprehensive Review of Chilkat Lake and River Sockeye Salmon Stock Assessment Studies written by Julie Bednarski and published by . This book was released on 2017 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1967 the Alaska Department of Fish and Game, Division of Commercial Fisheries, has operated a stock assessment program to estimate escapements and harvests of Chilkat sockeye salmon (Oncorhynchus nerka). Sockeye salmon were counted through a weir near the outlet of Chilkat Lake, and age, length, and sex data were collected and analyzed each year. Since 1994, mark-recapture studies were conducted to estimate Chilkat sockeye salmon escapements. Since the start of the 2008 season, DIDSON sonar has been used at the weir site to directly enumerate adult sockeye salmon escapement into Chilkat Lake. Visual scale pattern analysis was conducted to determine the proportion of Chilkat sockeye salmon harvested annually in the District 15 commercial drift gillnet fishery. In addition, limnological sampling was conducted in Chilkat Lake and analyzed each year. The intent of this report was to review Chilkat sockeye salmon stock assessment data from 1971 to 2016. The visual and DIDSON weir counts provide an index of escapement; however concerns regarding mark-recapture as a reliable index of abundance lead us to recommend eliminating mark-recapture studies in 2017 and, instead, maintain the DIDSON to estimate escapement into Chilkat Lake. We also recommend reviewing the current Chilkat Lake biological escapement goal to ensure that the goal and escapement estimates are in the same units, which is currently based on mark-recapture units. An average of 77,800 Chilkat Lake sockeye salmon were harvested annually in the District 15 commercial drift gillnet fishery (1976-2016). A comparison of historical fish wheel counts to Chilkat Lake escapement estimates demonstrates that the fish wheel project provides a rough indication of Chilkat Lake run strength. Zooplankton samples from Chilkat Lake were composed primarily of one species of copepod (Cyclops columbianus) and three species of cladocerans (Bosmina longerostris, Daphnia longiremus, and Daphnia rosea).
