Ecology

Life history

Breeding takes place from May to July. The juveniles leave the estuary and move to coastal waters where they spend the winter months. They go back to the estuary when it is spring from the middle of May. The females produce about 800,000 eggs. When the water temperature is 17–22 °C (63–72 °F), spawning will happen.
