Crab Bycatch Rates in Alaska
Crab bycatch rates for the groundfish fisheries in the Bering Sea and Aleutian Islands and the Gulf of Alaska.
Crab Bycatch Estimates
Information from NOAA Fisheries Alaska Region Catch Accounting System (CAS) on crab prohibited species bycatch by gear, area, target, week, and processing sector. Bycatch estimates are published for crab. The amount of groundfish catch (in metric tons), the bycatch of crab (in numbers of animals), and the rate of crab bycatch (in numbers of animals per metric ton of groundfish) are reported. Fisheries information on gear type, NMFS reporting area, target, week, and sector are also included. This report includes estimates for vessels with and without observers or electronic monitoring. This report includes the CDQ fishery. Groundfish catch is marked as confidential (‘C’) where fewer than three vessels are included. Note: Bycatch rates and estimates may change to reflect the updated information when new data enters or existing data are updated in CAS.
