NMFS implements regulations to limit the harvest of Pacific halibut by guided sport charter vessel anglers in International Pacific Halibut Commission Area 2C of Southeast Alaska to the guideline harvest level (GHL) of 931,000 lb (422.3 mt). The intended effect of this action is to reduce the poundage of halibut harvested by the guided sport charter vessel sector in Area 2C to the GHL while minimizing adverse impacts on the charter fishery, its sport fishing clients, the coastal communities that serve as home ports for this fishery, and fisheries for other species. This final rule implements three restrictions for the guided sport charter vessel fishery for halibut in Area 2C: a one-fish daily bag limit, no harvest by the charter vessel guide and crew, and a line limit equal to the number of charter vessel anglers onboard, not to exceed six lines.
