More Info


Distribution

Far northern Great Barrier Reef, Queensland, to at least Sydney, New South Wales, with juveniles as far south as Narooma; also at Lord Howe Island in the Tasman Sea. Elsewhere the species occurs in the tropical, west-central Pacific.

Inhabits bays, lagoons, and outer reefs, usually around coral or rocky outcrops in depths to 150 m.

Feeding

Feeds mostly on sand-dwelling fishes and crustaceans.

Biology

Forms spawning aggregations during spring and summer.

Fisheries

Targeted for the live reef fish food trade and aquarium trade in parts of its range, and the spawning aggregation is targeted by recreational fishers. 

Remarks

The Purple Rockcod is often misidentified as Epinephelus flavocaeruleus, which occurs in the Indian Ocaean.
