In Hawaii, “Ahi” refers to two species, the Bigeye Tuna and the Yellowfin Tuna. Similar in general appearance, the Bigeye may be recognized by its plump body, its larger head and its unusually large eyes. Caught in deeper, cooler water, Bigeye Tuna typically has a higher fat content than Yellowfin and is preferred by sashimi lovers. The majority of Hawaiʻi’s bigeye tuna are caught by deep-set longline fishing gear off shore of Hawaiʻi. The remainder of Hawaiian Bigeye Tuna landings come from handliners and trollers. Peak Bigeye landings occur from October through April. Learn More
