- Salmon migration is a fascinating natural phenomenon. Here are some key points about it:
- Young salmon spend one to three years in or near the stream where they were born. When they are about 6 inches long, they migrate to the ocean for feeding1.
- Species of salmon can spend from 1 up to 6 years in the ocean as they mature. They feed on small fish, squid, eels, and shrimp. When ready to reproduce, they return to freshwater rivers and streams2.
- All salmon species are born in freshwater streams and migrate to the ocean as juveniles. Adult salmon spend one to five years in the ocean before returning to freshwater to spawn3.
- Salmon are anadromous fish, migrating from the ocean to freshwater streams and rivers to spawn. The spawning season occurs in spring4.
- Most salmon species migrate during autumn, which is an important feeding event for predators and sport fishermen5.
