NMFS implements management measures described in a regulatory amendment (Regulatory Amendment 13) to the Fishery Management Plan for the Snapper-Grouper Fishery of the South Atlantic Region (FMP), as prepared by the South Atlantic Fishery Management Council (Council). This final rule revises the annual catch limits (ACLs), including sector ACLs, for 37 snapper-grouper species based on updated landings data. The purpose of this rule is to ensure that the ACLs are based on the best scientific information available, and to prevent unnecessary negative socio-economic impacts to participants in the snapper-grouper fishery and fishing community that could occur if the ACLs are not revised, in accordance with the provisions set forth in the Magnuson- Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act).
