The International Commission for the Conservation of Atlantic Tunas is an intergovernmental organization responsible for the management and conservation of tuna and tuna-like species in the Atlantic Ocean and adjacent seas.

It oversees the conservation and management of a variety of Atlantic marine species, including tunas, swordfish, marlin and sharks, and adopts measures to minimize bycatch of turtles and seabirds associated with these fisheries. This responsibility is shared among ICCAT’s 52 members, including the United States.
