Most people think that Yellowtail and Yellowfin are both tuna. They are not.
Yellowfin tuna is a beautiful red color. Yellowtail is pail-pink. Both have a nice fat content, which makes them taste so good. But thats where the similarities stop. Oh yeah, 1 more, their both fish. The yellowtail amberjack or great amberjack, Seriola lalandi, buri or hiramasa is a large fish found in the Pacific and Indian oceans. 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 the Hawaiian ?ahi, a name also used there for the closely related bigeye tuna. The species name, albacares (“white meat”) can also lead to confusion: in English, the albacore tuna (Thunnus alalunga) is a different species, while yellowfin is officially designated albacore in French and referred to as albacora by Portuguese fishermen.
