In this final rule, NMFS specifies a 2017 limit of 2,000 mt of longline-caught bigeye tuna for each U.S. participating territory (American Samoa, Guam, and the Northern Mariana Islands). NMFS will allow each territory to allocate up to 1,000 mt each year to U.S. longline fishing vessels in a valid specified fishing agreement. As an accountability measure, NMFS will monitor, attribute, and restrict (if necessary), catches of longline-caught bigeye tuna, including catches made under a specified fishing agreement. These catch limits and accountability measures support the long-term sustainability of fishery resources of the U.S. Pacific Islands and fisheries development in the U.S. territories.
