SEA BASS (HAPU’UPU’U)

Scientific Name: Epinephelus quernus
Hawaiian Name: Hapu`upu`u
Japanese Name: Mahata

Hapu`upu`u, commonly called Hawaiian sea bass or grouper, is only known to occur in the Hawaiian Islands and at seamounts just northwest of Hawaii. Groupers 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.

Hapu`upu`u is noted for its clear white flesh that is almost as delicate in taste as that of Hawaii's deepwater snappers.

It is a deepwater bottomfish usually caught at between 300 and 900 feet. In general, larger fish are caught at greater depths. 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 yield fish mostly in the 10 to 30 pound size range.

Hapu`upu`u keeps well when properly brined and iced.

FISHING METHOD

All Hawaii sea bass are line-caught. All sea bass are caught by deepwater handline gear with power reels.

SEASONALITY

The largest landings of hapu`upu`u usually occur in the fall and winter (October-December) and in the spring (February-April).
