In Hawaii Bigeye Tuna is one of the two species known as “ahi.” The other is Yellowfin Tuna. It is similar in appearance to Yellowfin, but has a more plump body and bigger head with unusually large eyes. Bigeye tuna is a highly migratory species. These fish are found around the world and can travel across an entire ocean. Bigeye tuna live in the tropical and warm temperate waters of the Atlantic, Pacific and Indian Oceans. Bigeye tuna isn’t a major target of U.S. commercial tuna fisheries in the Atlantic. Bigeye sometimes school with Yellowfin and Skipjack Tunas at the surface, therefore they tend to be caught as bycatch of these other fisheries.
Bigeye tuna meat has a reddish-pink color, firm texture and mild taste. It typically has a higher fat content than yellowfin and is great for sashimi and cooked preparations. Bigeye Tuna is low in saturated fat and sodium and is a very good source of protein, thiamin, selenium, and vitamin B6.
