A comprehensive global analysis reveals a staggering 81% decline in migratory freshwater fish populations since 1970. These vital species depend on long, interconnected river systems for their survival and reproduction. However, the proliferation of dams and increasing human pressures are severely fragmenting their essential migratory routes. This alarming trend indicates that hundreds of species are now in urgent need of coordinated international protection and conservation strategies. Experts emphasize that the critical step to preventing further irreversible collapse is the immediate restoration of river connectivity worldwide.
