Question: is yellowfin tuna the same as ahi tuna

Answer: Yes, Yellowfin is often marketed as ahi, from the Hawaiian ʻahi, 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.
