NMFS is closing the U.S. longline fishery for bigeye tuna in the Inter-American Tropical Tuna Commission (IATTC) Convention Area for the remainder of 2006, because the bigeye tuna catch in the Convention Area has reached the 150-metric ton (mt) limit for 2006. This action, implemented under the regulations for the Pacific Tuna Fisheries will contribute to efforts to end overfishing of bigeye tuna in the eastern tropical Pacific Ocean (ETP), consistent with recommendations by the IATTC that have been approved by the Department of State (DOS) under the Tuna Conventions Act. This action is intended to limit fishing mortality on the bigeye tuna stock caused by longline fishing in the Convention Area and contribute to the long-term conservation of the bigeye tuna stock at levels that support healthy fisheries.
