Occurs in estuaries, the surf zone and further offshore. In southern Angola, it is caught mainly in depths of 20-40 m. Becomes more abundant in Argyrosomus catches going northwards, indicating its preference for warmer waters. Fish up to 13,000 g were found to be immature. Adults are rarely found in Namibia but are said to be abundant in southern Angola, where the lack of permanent estuaries there suggests that this habitat type does not play an important role in the life history of this species (Ref. 11025).
