of one of the big fishes, the salmon. The cycle begins when adults lay the eggs between the small stones among the reeds in the upper

river

, where the movement is slow. It took 5 to 6 months for the eggs to become a fry. The fires change the location to fast

river

and stay at the lower

river

for the next 4

years

, until they grow up to smolts. The smolts are three times bigger than the fries and their length varies from 12 to 15 sm. After 4

years

, smolts move to the open sea, where, during the next 5

years

they grow up into adult salmons. The mature fish can achieve 70-76 cm length, which is ten times more, compared to fry. Interestingly, for breeding the adult salmon should come back to the

river

, where the cycle starts from the beginning.

Overall

, it takes almost ten

years

for salmon to breed,

while

almost half of the time they live in the

river

and half in the sea.

In addition

, during the life cycle, the fish changes the environment three times and increases their length significantly from stage to stage.
