This map is based on electronic tagging of Atlantic bluefin tuna (Thunnus thynnus) from 1996 to 2007. A team of international researchers officially classified the Atlantic bluefin as endangered in 2011. In addition to overfishing, the bluefin's defined spawning grounds can impact recovery efforts. When these areas are hit with oil spills, habitat loss, and other challenges, future generations of this top predator may be at stake. Learn more about fisheries in ourĀ Sustainable Seafood section.
