Yellowfin Tuna

According to the Hawaii Seafood Buyers Guide, yellowfin tuna is widely used in raw fish dishes, especially sashimi. This fish is also excellent for grilling. Yellowfin is often served seared rare.
Yellowfin buyers recognize two grades, "sashimi grade" and "other", although there are variations in the quality of "other" grades.
Yellowfin is becoming a popular replacement for the severely depleted supplies of southern bluefin tuna.
In 2010, Greenpeace International added the yellowfin tuna to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries.

The yellowfin tuna (Thunnus albacares) is a species of tuna found in pelagic waters of tropical and subtropical oceans worldwide.
Yellowfin is often marketed as ahi, from its Hawaiian name ?ahi although the name ?ahi in Hawaiian also refers to the closely related bigeye tuna. Although the species name albacares might suggest otherwise, the fish usually known as albacore is a different species of tuna, Thunnus alalunga. The yellowfin tuna is sometimes referred to as albacora by French and Portuguese fishermen.
