Tuna: Yellowfin sales remain steady, though worries about overfishing and mercury have cast a shadow over this popular species

摘要

Yellowfin, known in various locales as Pacific yellowfin, ahi (Hawaiian) and "light meat" tuna, could almost be classified as comfort food, with a mild, meaty taste similar to swordfish. It is served raw as sashimi and in sushi. Some is also canned. It's a somewhat darker product than canned al-bacore and is often blended widi skipjack tuna. Yellowfin (Thunnus albacares) belongs almost exclusively to the fresh market today. It is purchased mosdy as ahi in restaurants and as ahi steaks in supermarkets. Yellowfin is also the largest species of tuna, with market size running in the 7 1/2- to 20-pound range.
