NMFS issues this final rule to implement a framework action to the Fishery Management Plan (FMP) for the Reef Fish Resources of the Gulf of Mexico (Gulf) (Reef Fish FMP) as prepared by the Gulf of Mexico Fishery Management Council (Council). The action modifies the commercial annual catch limit (ACL) and annual catch target (ACT) regulations for three individual fishing quota (IFQ) program species complexes in the Gulf. This rule clarifies that the established commercial quotas are equal to the commercial ACTs and adds commercial ACLs to the regulations for three IFQ species complexes: Other shallow- water grouper (Other SWG), deep-water grouper (DWG), and tilefishes. The purpose of this rule is to optimize allowable harvest of IFQ species in the Gulf, while preventing overfishing, in accordance with National Standard 1 of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act).
