Freshwater Fish Populations Down 81% Since 1970, Report Finds
A sweeping global report has found that migratory freshwater fish populations have declined by roughly 81% since 1970. Dams and human pressures are blocking the migration routes these species depend on. Experts warn that restoring river connectivity is critical to preventing further collapse, with hundreds of species now requiring coordinated international protection.
A sweeping global report finds that migratory freshwater fish are in steep decline, with populations down roughly 81% since 1970. These species depend on long, connected rivers, but dams and human pressures are cutting off their routes. Hundreds of species now need coordinated international protection. Experts say restoring river connectivity is critical to preventing further collapse.
