NMFS has determined that the Atlantic bluefin tuna (ABT) Harpoon category annual quota for 1997 will be attained by July 7, 1997. Therefore, the 1997 Harpoon category fishery will be closed effective at 11:30 p.m. on July 7, 1997. This action is being taken to prevent overharvest of the Harpoon category quota.
