The yellowfin tuna (Thunnus albacares), is a type of tuna eaten by humans as food. It is found in open waters of tropical and subtropical seas worldwide. It is an epipelagic fish ranging in the top 100 m (330 feet) of the water column. It has been reported to be up to 239 cm (94 inches) in length and 200 kg (440 lb) in weight. The fish is also known as ahi tuna, after the Hawaiian word for "fire", due to the smoke from their fishing ropes rubbing violently on the gunwales of their wooden canoes while pulling the fish in. They are becoming a popular replacement for bluefin tuna because of the yellowfin\'s low conservation threat level and the severe depletion of the number of bluefin tuna.

The second dorsal fin and the anal fin are both bright yellow, thus the common name, and can be very long in mature specimens, as are the pectoral fins. The main body is very dark metallic blue, changing to silver on the belly, which has about 20 vertical lines.

School of yellowfin tuna

Yellowfins tend to school with fishes of the same size, including other species of tuna, and larger fish are often seen with dolphins, porpoises, whales and whale sharks. Yellowfins eat other fish, crustaceans, and squid.

Commercial fisheries catch yellowfin tuna with encircling nets (purse seines) and with longlines. The fish are mainly sold in frozen or canned form, but are also popular as sashimi.

Yellowfin tuna are a popular sport fish in many parts of their range and are prized for their speed and strength when fought on rod and reel as well as for their table qualities.

Yellowfin is popular in restaurants as the primary protein in an entree. Presented in much the same fashion as fine red meat, it is often cooked seared to rare to medium-rare, though it takes on a rich flavor similar to tri-tip when cooked through.
