Bigeye Tuna (Thunnus obesus)
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
Hawaiian Sea Bass is commonly called hapu‘upu‘u in Hawaii and grouper in other markets. This species is only known to occur in the Hawaiian Islands and at seamounts just northwest of Hawaii. Members of the grouper family are able to change skin colors to blend into their natural habitat, and the hapu‘upu‘u is no exception. Most hapu‘upu‘u seen in the market are black, but fish captured in certain locations may be brownish or reddish.
The largest landings of hapu‘upu‘u usually occur from October-December and February-April. The majority of the hapu‘upu‘u catch in recent years has come from the Northwestern Hawaiian Islands. Most of the hapu‘upu‘u caught off the main Hawaiian Islands are from 5 to 10 pounds in size, whereas the waters around the Northwestern Hawaiian Islands range from 10 to 30 pounds. This delicious fish is popularly consumed steamed. Learn More.
