This action would allow the National Marine Fisheries Service to reapportion unused Chinook salmon prohibited species catch within and between trawl sectors in the Gulf of Alaska groundfish fisheries to reduce the potential for early fishery closures. Amendments 93 and 97 to the Fishery Management Plan for Groundfish of the Gulf of Alaska and implementing regulations established Chinook salmon prohibited species catch limits for pollock and non-pollock trawl fisheries. If a sector reaches a prohibited species catch limit, the fishery is closed for the remainder of the fishing year--currently, the fishery management plan and regulations do not allow NMFS to reapportion unused Chinook salmon prohibited species catch among trawl sectors. Specifically, this action would: allow the National Marine Fisheries Service to reapportion remaining Chinook salmon prohibited species catch among trawl catcher vessel sectors and from the trawl catcher/processor sector to trawl catcher vessel sectors based on criteria established for inseason reapportionments and within specified limits; increase management flexibility without exceeding the current overall 32,500 Chinook salmon prohibited species catch limit or negating the current prohibited species catch limits under Amendments 93 and 97; and increase the likelihood that groundfish resources are more fully harvested, and minimize the adverse socioeconomic impacts of the fishery closures on harvesters, processors, and communities.
