The UN Convention on Migratory Species' Global Assessment reveals an 81% global decline in migratory freshwater fish since the 1970s. Nearly all 58 species listed face extinction. The Ganges-Brahmaputra-Meghna river system, a key migratory route from the Himalayas to the Bay of Bengal, is critically threatened by habitat fragmentation due to hydropower projects and altered water flows, especially upstream of major barrages like Farakka.
