Feeding and diet

The Red Bass feeds mainly on fishes but will also consume other prey such as crustaceans.

Life history cycle

Research of Marriott and Mapstone (2006) showed that the species is long lived. Up to 56 annual rings were found in otoliths of Red Bass from the Great Barrier Reef, indicating that the species can live at least 56 years.

Economic impacts

The Red Bass is an important commercial fish in many areas. In the western Pacific (including Australia), large individuals can potentially cause ciguatera poisoning.
