Every year on April 21, we celebrate an important environmental event – World Fish Migration Day.

Migratory fish make regular movements in order to find food or reproduce. Their migrations can occur only in fresh or salt water, and between rivers and seas (oceans) in both directions. Today, in the presence of a large number of dams, deteriorating climatic conditions and active fishing, it is difficult for migratory fish to follow their own route, and the number of this species is sharply decreasing. All these factors have an extremely negative effect on the condition of rivers, without which the functioning of ecosystems is impossible.

the purpose World Fish Migration Day there is an increase in awareness of the importance of fish migration and the involvement of humanity in the conservation of rivers.
