What it is
This species is a member of the emperor bream family. It grows to about 70 cm on average, with large specimens reaching 87 cm. The body is yellow, bronze or yellowish-brown, with a lighter belly. Scattered blue markings cover the flanks, and the cheeks are scaleless. Fins are whitish or yellow, with a yellow edge on the dorsal fin. Irregular dark bars sometimes appear on the sides.
Where it lives
Its range stretches from East Africa to southern Japan. Populations live in Australian coastal waters, the Red Sea, the Persian Gulf and New Caledonia. It occupies depths between 10 and 75 metres, though some records suggest deeper water. The fish prefers coral and rocky reefs, seagrass beds and mangrove swamps. It also swims over sandy substrates.
How it lives
Juveniles often form large schools. Adults are non-migratory and stay near structures like reefs. They feed primarily on hard-shelled prey such as molluscs, echinoderms and crustaceans. Polychaete worms and other fish make up a smaller part of their diet. This predator uses its strong teeth to crush shells.
Fish and people
Recreational anglers prize this fish for its fighting ability and taste. It is a major commercial species in New Caledonia. In the Persian Gulf, local fishers call it Sheri or Sherry. Approximately 3000 tonnes are caught annually in that region. The flesh is considered delicious and is widely consumed.
Status and threats
Overfishing has significantly reduced populations in the Persian Gulf due to expanded fishing fleets. Despite this pressure, offshore stocks remain at levels of lower concern. Current catches are viewed as near sustainable in many areas, though local declines are evident where fishing intensity is highest.
