Common Name

Biology
Occur in bays and coastal waters, including estuaries (Ref. 9563). Juveniles usually inhabit estuaries, bays and shallow continental shelf waters, while adults form schools near the sea bed on the continental shelf (Ref. 6390). Schools are found at the surface, in mid-water and on the bottom and are often associated with reefs and rough bottom (Ref. 9072). Schools are sometimes mixed with Caranx koheru and Arripis trutta (Ref. 9072). Feed on plankton by ram-filtering and suction feeding and on bottom invertebrates (Ref. 9072, 30206). Eggs are pelagic (Ref. 4233). Cultured only in Japan. (Ref. 4931). One of the best table fish 'being indeed the salmon of St. Helena
