'''''Corvina''''', ''Cynoscion accupa''is a fish common to Central and South American countries. It appears to ply the waters off Mexico, Central and northern South America. In Chile it is sometimes characterized as 'sea-bass'(not to be confused with "Chilean sea bass", marketed in the U.S., which is actually not a bass but Patagonian toothfish.) The Latin American corvina is much more like the sea bass caught in California waters than the so-called "Chilean sea bass." Corvina is probably not a bass but rather a croaker or related species. |
