Description of life cycle and mating behavior Juveniles migrate to sea or estuaries during their first summer, remaining there until they mature. After 1-2 years, they migrate upriver to breed. Spawners appear along the coast in late January-March, enter rivers when temperature reaches about 10°C, in late April and May. Spawning occurs from May to June on or above 15°C. Spent individuals migrate to estuaries and coastal lagoons or to sea near river mouths to feed. In autumn, they move to the sea to overwinter (Ref. 59043).
