## Abstract

This document combines two actions, an interpretive rule and a final action that both affect management of Atlantic billfishes. The interpretive rule adds the recently recognized species, roundscale spearfish (Tetrapturus georgii), to the definition of terms in the implementing regulations of the Magnuson-Stevens Fishery Conservation and Management Act (MSA) and the Atlantic HMS regulations. The final action will recognize the change of the genus of white marlin from Tetrapturus to Kajikia in the implementing regulations of the MSA and the Atlantic HMS regulations to reflect a recent taxonomic change. The intent of this interpretive rule and final action is to accurately and appropriately reflect the latest species determinations and taxonomic classification nomenclature, respectively. They will have no practical effect on management of Atlantic billfish.
