Migratory fish populations have crashed by more than 80% since 1970, with the fastest decline happening in South America and the Caribbean, where abundance dropped by 91% over the past 50 years.
Rivers no longer flow freely due to dams and barriers, estimated at 1.2 million in European rivers, causing declines in migratory fish. Other threats include pollution, urban, industrial wastewater, and climate breakdown.
Herman Wanningen, World Fish Migration Foundation founder, emphasizes the urgent need to save migratory fish populations facing catastrophic decline. These species are crucial for cultures, global food sources, and ecosystem sustainability.
