Bluefin Tuna: Overview Bluefin tuna are the most valuable fish
in the world, coveted for their fatty belly meat, used in sushi
as toro or maguro. In 2009, a single bluefin tuna sold for more
than $100,000 in Tokyo, where the world’s premium bluefin are
sold at auction. As a result, the incentives are overwhelming
for fishermen to drive bluefin toward extinction. Western
Atlantic bluefin tuna have been reduced by more than 82 percent.
The International Commission for the Conservation of Atlantic
Tunas (ICCAT) estimates that as few as 25,000 individual mature
bluefin tuna remain. Overfishing, loss of their prey and tuna
ranching all threaten bluefin tuna. Oceana is working in the
United States and Europe to protect bluefin tuna. By ending
overfishing, protecting the spawning grounds for these highly
endangered species and protecting their primary prey from
overexploitation, it may be possible to bring this magnificent
fish back from the brink of extinction. "Entourage" star Adrian
