Distribuição

Atlantic, Indian and Pacific: temperate and cold seas, mainly between 30°S and 50°S, to nearly 60°S. During spawning, large fish migrate to tropical seas, off the west coast of Australia, up to 10°S. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139). If the current exploitation continues, the population will be below 500 mature individuals in 100 years (Ref. 27905).

Biologia     Glossário (p.ex. epibenthic)

By maturity, most southern bluefin tuna lead an oceanic, pelagic existence (Ref. 6390). Spawning fish and larvae are encountered in waters with surface temperatures between 20° and 30°C. An opportunistic feeder, preying on a wide variety of fishes, crustaceans, cephalopods, salps, and other marine animals. Mostly canned (Ref. 9684). A specialized fishery for sashimi-quality has been developed recently by New Zealand fishers. In Japan, it is highly prized for the sashimi markets.
