Silver Trevally (Pseudocaranx georgianus) is distributed from Coffs Harbour in New South Wales across southern Australia to Perth in Western Australia. It forms schools over sandy bottom in estuaries, as well as gulf, nearshore coastal and shelf waters, where it feeds on small fish, benthic and pelagic invertebrates.
The population biology of Silver Trevally in South Australian waters is poorly understood. They are slow-growing and live up to 25 years in NSW waters, and 33 years in New Zealand waters. Spawning occurs between spring and autumn, with the larvae occurring in coastal waters, which may enter estuaries before settling out as juveniles.
