The regulatory amendment would establish consistent regulations among three management areas off the west coast of Puerto Rico (Abrir la Sierra Bank, Bajo de Sico, Tourmaline Bank). Regulations differ among these areas within federal waters, as well as between state and federal boundaries for the two areas (Tourmaline Bank and Bajo de Sico) that cross the two jurisdictions. The purpose of this amendment is to establish consistent federal regulations across the three areas, while ensuring adequate protection of spawning aggregations of reef fish and the benthic habitat supporting those aggregations, which also serves as residential, recruitment, and foraging habitat for a variety of species. The proposed action would: Modify the length of the seasonal closures; modify reef fish, spiny lobster, and highly migratory species fishing regulations; modify anchoring restrictions; and modify spearfishing prohibitions within the management areas.
