Opah Fish

Opah Flavor Scale

Back to Finfish

Opah Flavor Profile

Fresh Opah, also called Moonfish, has translucent pinkish flesh and beautiful multi-colored skin. The tender top loin of Opah is a light salmon-orange or pink-rose color and is often used for sashimi.  The flavor of the top loin is sweet & lean with a texture somewhat like tuna. 

The side and lower flesh of Opah is the same light salmon-orange color at the top but fades to a paler color at the bottom and is too fibrous to be used for sashimi but still becomes very tender after cooking.  With a robust flavor similar to tuna or swordfish, the lower loin is higher in natural oil than the top loin and has a fat content which can be higher than Salmon.

The cheek meat is dark red.  And the breastplate flesh is bright red.  All the flesh turns white after cooking except for the breastplate which turns brown.

Opah is generally not a targeted commercial species, but instead is usually a bycatch of other fisheries such as the tuna or mahi mahi fishery. The concern with Opah is the longline gear which is commonly used. There is considerably bycatch of unintended species (including Opah!) which is why it is rated "good alternative" or "avoid".
