This book was released on 2018 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes bottom trawl survey data used to assess Tanner crab Chionoecetes bairdi abundance within the Alaska Department of Fish and Game's Central Region. Trawl surveys replaced pot surveys as the primary method of assessing Tanner crab in Central Region in the early 1990s. Data for the Central Region were collected from 2 management districts in the Lower Cook Inlet Management Area: 1) the Southern District (1990-2013), and 2) the Kamishak Bay and Barren Islands Districts (1990-2012). Data were also collected from the Prince William Sound Management Area (1991-2015). Since 1993 in the Southern District, and 1990 in the Kamishak Bay and Barren Islands Districts, the estimated abundance of legal male Tanner crab has not exceeded the minimum stock size threshold defined in regulation that is necessary to open a commercial fishery (Alaska Administrative Code 5 AAC 35.408). Bottom trawl survey methods have changed through the history of the survey and those changes are documented in this report. Abundance trends of legal and sublegal male and female Tanner crab are also described along with trends in recruitment. Analysis and harvest strategy recommendations to create a management plan for commercial and noncommercial Tanner crab fisheries in the Prince William Sound Management Area are presented.

This book was released on 2022 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes results from the large-mesh bottom trawl survey that took place June through September 2021 to assess crab and groundfish resources in the Kodiak, Chignik, South Peninsula, and Eastern Aleutian Tanner crab Chionoecetes bairdi management Districts. A total of 337 trawl hauls were conducted to assess relative abundance and condition of commercially important crabs, as well as spatial distribution, species composition, size frequency, and catch per unit effort of commercially important groundfish. Survey estimates indicated that mature and legal male Tanner crab abundances were sufficient to support commercial fisheries in 3 sections of the Kodiak District, the Chignik District, and both sections of the South Peninsula District. Red king crab Paralithodes camtschaticus abundance estimates in each of the surveyed management areas remain too low to consider opening a red king crab commercial fishery. Arrowtooth flounder Atheresthes stomias, flathead sole Hippoglossoides elassodon, walleye pollock Gadus chalcogrammus, and yellowfin sole Limanda aspera, were the dominant groundfish captured during the survey. report summarizes results from the large-mesh bottom trawl survey that took place June through September 2020 to assess crab and groundfish resources in the Kodiak, Chignik, and South Peninsula Tanner crab Chionoecetes bairdi management districts.
