Chinook Salmon Life Cycle at Life

Chinook Salmon Life Cycle. Chinook salmon from idaho tend to spend one to five years in the ocean before returning to fresh water to spawn, with two years being the most common. This means they start their lives in freshwater, migrate to the ocean where they grow, then return home to their natal, or birth, streams to spawn and die.

Ios is composed of six primary life cycle components that can be affected by water temperature, river flow, or ocean productivity including 1) spawning (water temperature), Survival of chinook salmon (o. Chinook have a complicated life cycle that takes years to complete and can span thousands of miles from headwater streams to the north pacific ocean. During the oceanic portion of their life cycle, these fish are primarily concerned with growing and storing energy that they will require for successful reproduction.
