NMFS issues regulations amending the limited access program for charter vessels in the guided sport fishery for Pacific halibut in the waters of International Pacific Halibut Commission Regulatory Area 2C (Southeast Alaska) and Area 3A (Central Gulf of Alaska). These regulations revise the method of assigning angler endorsements to charter halibut permits to more closely align each endorsement with the greatest number of charter vessel anglers reported for each vessel that a charter business used to qualify for a charter halibut permit. This action is necessary to achieve the halibut fishery management goals of the North Pacific Fishery Management Council.
