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).
发现于大洋性水域了, 有时不远离海岸.(参考文献 13628) 用鲣鱼形成大的混合鱼群。 它的产卵场被设置相当外海。 捕食表面的且深-海洋鱼，乌贼，片脚类动物，虾，螃蟹与口足目甲壳类与十足目幼生。 给黑鳍鲔鱼的最大的渔场操作外海的古巴与使用活饵的东南方海岸与杆。 生鲜使用, 乾燥或盐腌, 罐装及冷冻.(参考文献 9987)
