What is the Life Cycle of Chinook Salmon?
The life cycle of chinook salmon is divided into several stages, each playing a crucial role in the species' survival. The stages include:
- Egg: Chinook salmon eggs are laid in gravel nests called redds, typically in freshwater streams.
- Alevin: After hatching, the young fish, known as alevins, remain in the gravel and feed off their yolk sacs.
- Fry: Once they have absorbed their yolk sacs, alevins become fry and begin to swim freely in the water.
- Smolt: As the fry grow, they undergo a transformation into smolts, preparing for their journey to the ocean.
- Adult: After spending several years in the ocean, chinook salmon return to freshwater to spawn.
