Rivers in Peril: Global Migratory Fish Declines Threaten Food and Culture
A global assessment finds migratory freshwater fish collapsing due to dams, overfishing, habitat loss and pollution; 97% of migratory species are at risk of extinction, mega-fish in the Mekong have declined ~95% since 1970, and cross-border cooperation under the Convention on Migratory Species is needed to restore river connectivity and protect livelihoods and diets across major basins.
