Keta Salmon Biology

Keta salmon have a fascinating and complex life cycle that takes them on an epic journey across thousands of miles.

Here are some key aspects of their biology:

• Anadromous – They hatch in freshwater streams and rivers, migrate to the ocean to feed and mature, then return to their natal rivers to spawn.

• Homing Instinct – Using their acute sense of smell, keta salmon can navigate back to their exact place of birth to reproduce after years roaming the ocean.

• Spawning – Adults return to freshwater in the fall to spawn. Females lay eggs in gravel nests called redds, males fertilize them. After spawning, the adults die.

• Juvenile Stage – Eggs hatch into alevins, which mature into fry that feed and grow in freshwater from spring into summer before migrating out to the ocean.

• Appearance Changes – Coloring and body shape changes significantly as they move between life stages. Spawning adults develop fangs hooked jaws and bright markings.

• Two Races – Summer and fall runs, based on when they return to spawn.
