Pacific bluefin tuna fishery : The commercial and recreational capture of Pacific bluefin tuna across the North Pacific. Fishing pressure is the main direct source of human-caused mortality.
Pacific bluefin tuna conservation : Efforts to rebuild and protect Pacific bluefin tuna populations through catch controls and monitoring. Conservation measures respond to heavy fishing and a depleted spawning population.
Atlantic bluefin tuna : A large bluefin tuna species, Thunnus thynnus, native to the Atlantic Ocean and Mediterranean Sea. It is the closest familiar comparison, but belongs to a different species and ocean population.
Regional endothermy : The ability of some animals to keep parts of the body warmer than surrounding water or air. Heat-retaining tissues let the tuna maintain warm swimming muscles in cold water.

Western and Central Pacific Fisheries Commission : An international organization that manages tuna fisheries in the western and central Pacific Ocean. Its members set catch measures affecting much of the species’ fishing range.
Southern bluefin tuna : A bluefin tuna species, Thunnus maccoyii, found in the southern Atlantic, Indian, and Pacific oceans. Its southern-hemisphere range distinguishes it from the North Pacific species.
Thunnus : A genus of large, fast-swimming marine fishes that includes bluefin, yellowfin, and albacore tunas. Pacific bluefin is one of several migratory species in this tuna genus.
