Description of life cycle and mating behavior Most juveniles migrate to river mouth in first summer and remain at sea until they mature. Males migrate upriver at 3-4 years, females at 4-5. They start entering rivers when temperatures reach 14-18°C, mainly in May to spawn when temperatures rises above 20°C. After spawning, spent individuals migrate back to sea, but many die before they do (Ref. 59043).
