Found in oceanic waters, sometimes not far from the coast (Ref. 13628). Forms large mixed schools with the skipjack tuna. Its spawning grounds are located well offshore. Preys on surface and deep-sea fishes, squids, amphipods, shrimps, crabs and stomatopods and decapod larvae. The largest fishery for blackfin tuna operates off the southeastern coast of Cuba and uses live-bait and pole. Utilized fresh, dried or salted, canned and frozen (Ref. 9987).
