Description:Pacific halibut (Hippoglossus stenolepis) is found in coastal waters throughout the North Pacific. Off the U.S. West Coast of the United States, it inhabits continental shelf areas (<150 fth) from Washington to central California (Clark and Hare 1998). Pacific halibut has long supported a directed commercial fishery in the U.S. and Canada, but it is also caught as bycatch in other fisheries that target demersal species inhabiting similar depths and seafloor habitat types (IPHC & Gustafson 2019, Jannot et al. 2020). This NWFSC Processed Report presents the methods used for estimating P. halibut discards on Individual Fishing Quota (IFQ) vessels. The methods presented here are for making estimations for in-season reporting and when special cases arise. Estimates from these methods are reported in-season to the NOAA Fisheries West Coast Region’s (WCR) IFQ Program for Pacific Coast Groundfish, also known as the Vessel Account System. This report presents methods only—no data are presented. Detailed descriptions of data sources, collection, and reporting for these fisheries in relation to P. halibut bycatch are given in Jannot et al. (2020). The Vessel Account System (VAS) is a WCR database that allows fishers to manage their IFQ quota pounds. On a weekly basis, WCGOP provides trip-level estimates of discarded P. halibut individual bycatch quotas (IBQ) to the Pacific States Marine Fisheries Commission (PSMFC).
