NMFS implements regulations to limit the harvest of Pacific halibut by guided sport charter vessel anglers in International Pacific Halibut Commission (IPHC) Regulatory Area 2C (Area 2C) of Southeast Alaska to one halibut per day. This action is necessary to reduce the halibut harvest in the guided sport charter vessel (guided) sector. The intended effect of this action is to manage the harvest of halibut in Area 2C consistent with an allocation strategy recommended by the North Pacific Fishery Management Council for the guided fishery and the commercial fishery. This final rule implements three restrictions for the guided 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.
