Salmon invade fast-flowing freshwater systems and swim in the rivers where they were born to find suitable spawning grounds. The flowing water and river habitat provide both eggs and young salmon with sufficient oxygen and shelter, increasing their survival.
In the ocean, Salmon eat a wide variety of prey, including:
Capelin, Atlantic herring, sand lance, barracuda, lanternfish, and other fish. Crustaceans such as amphipods and krill cephalopods such as squids and octopuses, and Polychaete worm.
Salmon and other fish swim upstream because they are part of the reproductive life cycle. Salmon are born in freshwater rivers, spend most of their lives in the ocean, and then return to where they were born to lay their eggs.
