Book excerpt: This report summarizes results from the large-mesh bottom trawl survey that took place June through September 2022 to assess crab and groundfish resources in the Kodiak, Chignik, South Peninsula, and Eastern Aleutian Tanner crab Chionoecetes bairdi management districts. A total of 369 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.
