four major stages in its life(

eggs

,fry,smolt and adult

salmon

).These stages occur in different environmental conditions where they have the optimal background for growing into the next stage.

Besides

the life span of

salmon

fish is around ten years.

Initially

,adult

salmon

from the sea migrate into rivers and lay their

eggs

in the upper river where water currents move slowly, making

eggs

not to be disturbed by flowing water.

Eggs

are laid in the vicinity of small stones and reeds and it takes 5-6 months to hatch the

eggs

. Afterwards,3-8 cm long fry is released from the hatched

eggs

and they swim into deep rivers and stay in the speedy water waves for approximately four years before being transformed into the smolt stage where they grow into a larger size measuring 12-15 cm.

Subsequently

,smolts swim into the sea and become adults of 70-76 cm in length and reside there for 5 years.
