The Pacific bluefin tuna (Thunnus orientalis) is a predatory species of tuna found widely in the northern Pacific Ocean, but it is migratory and also recorded as a visitor to the south Pacific.[3][4]
In the past it was often included in T. thynnus, the 'combined' species then known as the northern bluefin tuna (when treated as separate, T. thynnus is called the Atlantic bluefin tuna).[5] It may reach as much as 3 m (9.8 ft) in length and 450 kg (990 lb) in weight.[6]
Like the closely related Atlantic bluefin and southern bluefin, the Pacific bluefin is a commercially valuable species and several thousand tonnes are caught each year. It is considered overfished, but not subject to overfishing.[3][7][8] It is considered near threatened by the IUCN and PEW.[3][9] Monterey Bay Aquarium's Seafood Watch program have placed all bluefin tunas on the "Avoid" list and they are also placed on the "Red List" by Greenpeace and the Blue Ocean Institute.[10][11][12]
