Atlantic Bluefin Tuna (Thunnus thynnus)
Did You Know?
- "Weak" fishing hooks protect bluefin tuna in Gulf of Mexico, but allow catch of yellowfin tuna and swordfish.
- Bluefin tuna are able to thermoregulate, which means they can keep their body temperature warmer than the surrounding water.
- The can swim over 45 mph (72 km/h) in short bursts.
- Prized as sushi, a single fish can sell for tens of thousands of dollars.
|average 550 pounds (250 kg); can reach up to 2,000 pounds (900 kg)|
|average 6.5 feet (2 m); can reach up to 13 feet (4 m)|
|Fish, such as herring, anchovy, sand lance, sardine, sprat, bluefish, and mackerel; juveniles also eat crustaceans and cephalopods|
Atlantic bluefin tuna are found throughout the North Atlantic Ocean and adjacent seas, including the Mediterranean Sea.
They are "pelagic", highly migratory species occupying coastal and open ocean areas up to depths of 650 feet (200 m).
The Atlantic bluefin tuna is the largest of the tuna species.
As large predators, bluefin tuna play an important role in pelagic ecosystems.
In May 2010, the Center for Biological Diversity (CBD) submitted a petition [pdf] to list Atlantic bluefin tuna under the Endangered Species Act (ESA). The 90-day finding states that the petition contains "substantial information" that the petitioned action may be warranted; it is not a listing for Atlantic bluefin tuna.
On May 27, 2011, after an extensive scientific review, NOAA announced that Atlantic bluefin tuna currently do not warrant species protection under the Endangered Species Act.
NOAA formally designated the western Atlantic, eastern Atlantic, and Mediterranean stocks of bluefin tuna as species of concern. This places the species on a watchlist for concerns about its status and threats to the species under the Endangered Species Act.Kingdom: Animalia
