The Stages of Salmon Life Cycle

Gecko published on

Eggs: In the fall, salmon ❗️[ˈsamən] deposit eggs in gravel nests. Adult salmon die after spawning.

Alevin: Alevin hatch from the eggs and remain in their nests until they absorb their yolk sac. In the spring, they emerge as fry.

Fry: Fry spend one or two years in fresh water. They grow and develop parr marks to help avoid predators.

Smolt: When fry turn silver, they are called smolt.

Adult: Salmon mature after spending one to three years in the ocean.

Spawners: In the summer and fall, adults return to their original spawning areas.

And the life cycle begins again…


gravel = very small, rounded stones, often mixed with sand

spawning = laying eggs

hatch = come out of an egg

yolk sac = a membranous structure resembling a bag and containing yolk attached to the embryos of reptiles and birds and the larvae of some fishes

parr marks = vertical striped markings on the fish body
