The earth’s waters have lost more than three-quarters of its migratory fish freshwater species since 1970. The freshwater fish species in Europe have been hit the hardest, however, the data used from the Living Planet Index project lacked sufficient data for Africa, Asia, Oceania and South America. Human activity, including the creation of dams, culverts as well as habitat loss, overfishing and pollution are the main culprits. Climate change has also affected the fish. This is the conclusion of the first global assessment of migratory freshwater fish species, published in a report by the World Fish Migration Foundation. SitaraBirdLogoTiny
