Many migratory fish species are severely threatened. The main causes are man-made obstacles like dams, weirs and sluices, which disrupt the natural flow of rivers and prevent fish migration. Migratory fish make up a crucial link in the food chain and play an important role in healthy and productive river systems. Furthermore, they provide an important food supply and livelihood for millions of people around the world.

The World Fish Migration Day, celebrated on 21 April, is a one day global celebration to create awareness on the importance of open rivers and migratory fish. Learn more about how to engage here.

This is their message for the World Fish Migration Day organization.
