But why do salmon swim upstream? Salmon enter fast-flowing freshwater systems and swim up their natal rivers to find a suitable spawning location. The rivers’ running water and habitat provide both plenty of oxygen and shelter for the eggs and juvenile salmon, which increases their rate of survival.
A salmon run is an annual fish migration event where many salmonid species, which are typically hatched in fresh water and live most of the adult life downstream in the ocean, swim back against the stream to the upper reaches of rivers to spawn on the gravel beds of small creeks.
