This diagram provides a clear description of the life cycle of a sea salmon. Overall, there is a total of 7 natural developmental stages taken place, starting with laying eggs in the fresh water and finishing at becoming spawning salmon.
To start with, female adult salmon lays eggs in freshwaters like rivers or lakes. Then, these eggs hatched into alevin in about 3 months. At this time, they feed off on the yolk sac for several weeks. Then, these alevins develop into fry at 5 to 10 weeks old and swim. After several months, the fries grow into parr, and then they develop finger markings. In the next stage, they become smolts from 1 to 3 years and will group and head out to sea. When spending 1 to 8 years at sea, they reach their maturity. Finally, spawning adult salmon start the journey back to freshwater for laying eggs and die within 2 weeks. And the life cycle starts again.
