Alaska Region's data on salmon incidental catch in the Alaska groundfish fisheries, including stock of origin and coded wire tag (CWT) data for salmon. Report supplements the annual report on salmon incidental catch and salmon bycatch reduction measures.

Annual and updated reports on salmon incidental catch in the Alaska groundfish fisheries. Includes information on salmon bycatch reduction measures and sources for the genetic composition of salmon caught in these fisheries.

Hatchery and Genetics Management Plans (HGMPs)

The Snake River is a tributary to the Columbia River. The proposed management plans include fall Chinook salmon fisheries, coho salmon fisheries, and Oregon’s resident trout fishery in the Snake River Basin.

This analysis addresses the groundfish trawl and non-trawl sectors and their impacts on salmon bycatch in support of the Endangered Species Act (ESA) salmon consultation for the groundfish fishery.

The Gulf of Alaska (GOA) is known as a feeding habitat for multiple brood years of Chinook salmon (Oncorhynchus tshawytscha) originating from many different localities in North America and Asia. Determining the geographic origin and stock composition of salmon caught in federally managed fisheries is essential to understanding whether fisheries management could address conservation concerns. This report provides genetic stock identification results for Chinook salmon Prohibited Species Catch (bycatch)samples collectedin the GOA from thetrawl fisheriesfor walleye pollock (Gadus chalcogrammus) and catcher vessel (CV) trawl fisheries for rockfish (Sebastes spp.). The National Marine Fisheries Service (NMFS) and Alaska Department of Fish and Game (ADF&G) geographical statisticalareas associated with the groundfish fishery are shown in Figure 1 and are used later in the report to describe the spatial distribution of the Chinook salmon bycatch and genetic samples. Allanalyses used a single nucleotide polymorphism (SNP) baseline provided by ADF&G (Templin et al. 2011; Appendix 1),the same baseline used to estimate previous stock compositions of samples from the Chinook salmon bycatch of the federally managed GOA trawl fisheries(Guthrie et al. 2013, 2016, 2017; Guyon et al. 2014, 2015a,b; Larson et al. 2013). For additional information regarding background and methodology refer to the Chinook salmon bycatch report prepared previously for the 2008 Bering Sea trawl fishery (Guyon et al. 2010).
