NMFS is developing a proposed rule to implement Amendment 53.  The proposed rule would modify management of South Atlantic gag and black grouper.  Because gag is overfished and undergoing overfishing, actions for gag include establishing a rebuilding plan, revising annual catch limits, sector allocations, management measures, and recreational accountability measures.  Amendment 53 would also modify recreational management measures for black grouper.  Amendment 53 and the proposed rule would end overfishing of South Atlantic gag, rebuild the stock, and achieve optimum yield while minimizing, to the extent practicable, adverse social and economic effects.
