Opah or Moonfish is one of the most colorful of the commercial fish species available in Hawaii. A silvery-grey upper body color shades to a rose red dotted with white spots toward the belly. Its fins are crimson, and its large eyes are encircled with gold. The moonfish's large, round profile may be the origin of its name. Moonfish caught in Hawaii range from 60 to over 200 pounds in round weight.
The Opah's large-grain flesh is rich and fatty, with a versatility of use that is attractive to restaurants. Opah is used for sashimi, for broiling, and occasionally for smoking.
