NMFS closes the fishery for large medium and giant Atlantic bluefin tuna (ABT) conducted by Angling category fishermen in the southern area (the waters off Delaware and states south). Closure of this fishery is necessary because the 4 metric tons (mt) of large medium and giant ABT allocated for this subcategory is projected to be attained by December 17, 1997. The intent of this action is to prevent overharvest of this subcategory. In addition, effective January 1, 1998, the daily catch limit for ABT is adjusted to one fish per vessel, which may be from the school, large school, or small medium size class. This action is being taken to lengthen the fishing season and ensure reasonable fishing opportunities in all geographic areas without risking overharvest of the Angling category.
