Then at some point in their development the fish swim downstream to river estuaries where rearing continues.
. The red part is correct. Egg fry smolt and adult. Thus the life cycle of a salmon fish springs from the incubation stage in a river.
Finally the adult salmon will find a mate and lay salmon eggs by the upper river. At the beginning of the life cycle eggs are laid and incubated in rivers. Commencing with the initial phase of salmon fish is incubation and emerged in the river.
After emerging from eggs the young salmon spend the next stage of their lives being reared in freshwater areas. Overall a salmon fish goes through six main phases to fully grow from their hatching period and spends its life in three distinct locations. As shown in the diagram in the upper where the water flows slowly countless salmon eggs are laid and incubated between.
After initially hatching in a slow moving river each Salmon spends roughly equal amounts of its 10 year cycle in fast flowing freshwater and open seas. Overall there are 3 distinct stages in the life cycle of a salmon starting with the egg stage and ending with the adult stage. For approximately 5 years into an adult salmon which they could grow around 70-76 cm long.
Fry lives between 5 to 6 months in this location. Besides before moving on to the ocean there is a common area named an estuary where estuary rearing occurs. Detail 1 To begin with the adult salmon lay eggs upriver where the current is slow.
The smolt spend around 5 years on. Overall the salmons life cycle has 3 phases. Camouflage from any prey.
