A better understanding of spatial structure and mixing may help fisheries managers to successfully rebuild populations to sustainable levels while maximizing catches. The Pacific bluefin tuna is not yet listed, but overfishing is now occurring, according to the National Marine Fisheries Service. Closing life cycles for SBFT and ABFT will result in more health issues as naïve fish from hatcheries will be transferred to marine cages, as has been witnessed for hatchery-reared Pacific bluefin tuna (PBFT) in Japan.

Countries involved in managing bluefin tuna fisheries are set to face-off over a Japanese proposal to raise its catch quotas for the fish, highly prized for sushi and sashimi. While it is likely that Atlantic bluefin tuna have been overfished for many years, the actual population size is unknown and has become a controversial issue.

Atlantic Bluefin Tuna are believed to grow up to 15 feet in length and weigh up to 2,000 pounds. Atlantic bluefin tuna (Thunnus thynnus) is considered to be overfished, but the status of its populations has been debated, partly because of uncertainties regarding the effects of mixing on fishing grounds.

They inhabit the northern waters of the Pacific, from the East Asian coast to the western coast of North America. In the North Atlantic, bluefin tuna are well managed so their numbers are growing. Estimates are that Atlantic and Southern Bluefin tuna populations have declined by 80-85%. Although Pacific-wide populations are well below target levels, U.S. wild-caught Pacific bluefin tuna is a smart seafood choice because it is sustainably managed under rebuilding measures that limit harvest by … In 1996, the IUCN listed the Atlantic bluefin tuna as ‘endangered’: the population was down by 85%.
