Biology. Lives up to 30 years. Spawns first time at 4–7 years and about 350 (male) and 420 (female) mm SL. Spawns pelagic in open sea, in January–June at temperatures above 9°C. Larvae planktonic. Juveniles move inshore as they grow, aggregating in brackish estuarine nursery areas where they usually remain until second summer. Large juveniles and adults exhibit a complex migratory pattern at sea, moving inshore and into estuarine freshwaters during summer to feed. Juveniles feed on invertebrates, taking more fish as they grow. Adults are piscivorous.

Conservation status. NT; numbers have declined over the last 20 years due to overfishing.
