, the

salmon

eggs are placed between small-sized stones near the reeds and

this

stage takes approximately five or six months. In the subsequent stage, the eggs turn into fries with less than 8 cm long. Afterwards, they move to a lower

river

with fast water flowing. After four years of habitation in the lower

river

, they become larger with a length of 12 to 15 cm and are called smolt. In

this

size, they move to the open sea and their life takes about five years there. After the five-year period, salmons rise and become seven times as long as smolts.

Finally

to breed and
