The Atlantic bluefin tuna (Thynnus thunnus) is a sleek, 300-pound fish and a top predator in the ocean—but it is endangered from overfishing. Bluefin tuna is one of the most highly-prized fishes used in sushi and single fish will sell for tens of thousands of dollars.
Because it is endangered, there are strict regulations on how many fish can be caught each year. On Monday, the International Commission for the Conservation of Atlantic Tunas (ICCAT) met and decided to raise the quota (number of allowed fish caught), but by less than previous years.
Conservationists are celebrating this as a victory because the commission took the advice of the fisheries scientists to give the fish more time to recover before raising catch limits.
A related species of bluefin tuna, the Southern bluefin tuna (Thunnus maccoyii), is critically endangered, which means there is no sign that its population is growing.
