Tuna and tuna-like fishes are highly migratory, and stocks cross numerous international boundaries.ICCAT is involved in management of 30 species, including the Atlantic bluefin (Thunnus thynnus thynnus), yellowfin (T. albacares), albacore (T. alalunga) and bigeye tuna (T. obesus); from the billfishes, swordfish (Xiphias gladius), white marlin (Tetrapturus albidus), blue marlin (Makaira ...
The Atlantic bluefin tuna is a close relative of one of the other two bluefin tuna species, the Pacific bluefin tuna. The southern bluefin tuna , on the other hand, is more closely related to other tuna species such as yellowfin tuna and bigeye tuna , and the similarities between the southern and northern species are due to convergent evolution.
The southern bluefin tuna (Thunnus maccoyii) is a tuna of the family Scombridae found in open southern Hemisphere waters of all the world's oceans mainly between 30°S and 50°S, to nearly 60°S. At up to 2.5 metres (8 ft 2 in) and weighing up to 260 kilograms (570 lb), it is among the larger bony fishes.
These fish make long migrations across the high seas, and are fished by many nations. Highly migratory fish also cross boundaries without regard for international laws. In particular, they enter the EEZ zones of the U.S., which means they become important species also for U.S. coastal fisheries. In the Atlantic, overfished species include: [5]
A 276-kilogram bluefin tuna that was auctioned for 207 million Japanese yen (about $1.3 million) is carried into an Onodera sushi restaurant after the first tuna auction of the New Year in Tokyo ...
Atlantic Bluefin Tuna and Patagonian Toothfish had a negative Δmislabel, which could represent an incentive to mislabel in order to facilitate market access for illegally-landed seafood. [43] Most species had price differentials close to zero—suggesting other incentives are likely influencing seafood mislabeling.
