Salmon fish are anadromous species, ie species that migrate to breed. Salmon born in freshwater, migrate to the ocean, then return to fresh water to reproduce.
There is a belief that salmon always return to the same place where he was born to breed.
Research shows this, but the reason why it happens and how salmon can save the memory is still a mystery.
Young salmon lived in the freshwater where they were born, for three years before migrating to the ocean and live in saltwater.
During this period, their color was silvery. It is estimated that only 10% of the number of eggs that successfully reached this stage.
