NMFS issues a final rule that would allow the retention of halibut less than 32 inches (81.3 cm) with the head on, or less than 24 inches (61 cm) with the head off (undersized halibut) caught with setline gear in International Pacific Halibut Commission (IPHC) Regulatory Area 4E for personal use. Commercial sale of undersized halibut would remain prohibited. This action is necessary to implement the recommendation of the North Pacific Fishery Management Council (Council) to allow the legal harvest of undersized halibut by persons using Community Development Quota (CDQ) in Regulatory Area 4E. This action is intended to provide for the continued existence of the customary and traditional food practices of indigenous inhabitants by allowing them to retain all halibut caught with setline gear in Regulatory Area 4E.
