NMFS amends the regulations governing the Atlantic tuna fisheries to: Divide the large school-small medium size class quota and the large medium-giant quotas of Atlantic bluefin tuna (ABT) Angling category into north and south regional subquotas; establish a new tuna permit program to provide for category changes, annual renewals, and the collection of fees; require self-reporting for ABT landed under the Angling category; prohibit the retention of ABT less than the large medium size class by vessels permitted in the General category; and prohibit fishing for ABT by persons aboard vessels permitted in the General category on designated restricted-fishing days. The regulatory amendments are necessary to achieve domestic management objectives for the Atlantic tuna fisheries.
