NMFS issues this final rule to correct and clarify 50 CFR part 648, which contains regulations implementing the fishery management plans (FMPs) for: Summer flounder, scup, and black sea bass; Atlantic sea scallops; Northeast multispecies; Atlantic surf clams and ocean quahogs; Atlantic mackerel, squid, and butterfish; and Atlantic salmon. During the consolidation of these FMPs into one part (50 CFR part 648), unintended omissions and changes were made. This document corrects those errors.
