This rule would limit Chinook salmon prohibited species catch in the Western and Central Gulf of Alaska non-pollock trawl fisheries. Chinook salmon is a fully utilized species in Alaska coastal subsistence, recreational, and commercial fisheries. In recent years the returns of Chinook salmon to some Alaska river systems have been below the biological escapement goals established by the State of Alaska. This action is necessary to minimize the catch of Chinook salmon to the extent practicable in the Gulf of Alaska non-pollock trawl fisheries. The rule would establish a 7,500 Chinook salmon prohibited species annual limit that would be seasonally apportioned among fishing vessel sectors. If a sector reached its Chinook salmon prohibited species limit, further directed fishing for groundfish by vessels in that sector and season would be prohibited. Vessel operators would be required to retain salmon until the number of salmon has been determined by the vessel or plant observer and the observers data collection has been completed. About 70 vessels could be affected by this action. This action could reduce revenues from the fisheries, if the Chinook salmon prohibited species limit is reached before the groundfish quota is harvested. The action may also increase costs if vessel operators move fishing operations or take other actions to lower their catch of Chinook salmon.
