"From the Amazon to the Mekong, migratory freshwater fish underpin food security for millions, but over 300 species need urgent conservation intervention, warns a new UN report."
"Beneath the surface of the planet’s rivers and lakes, the historically heaving migrations of freshwater fish are thinning out. The blubbery-lipped Siamese giant carp of Asia’s Mekong River, the mottled brown goonch of India’s Ganges and the ancient-in-appearance beluga sturgeon of Europe’s Danube River are declining.
Facing existential threats along their migratory paths, an ecological collapse is taking place largely out of sight.
Declining faster than many terrestrial populations, 325 migratory freshwater fish species have been identified as candidates for urgent conservation efforts by the United Nations’ Convention on the Conservation of Migratory Species of Wild Animals (CMS). These populations—critical for river health and economic output—have already declined by over 80 percent since 1970.
This week, ambitious international safeguarding efforts will be unveiled at CMS’ 15th annual meeting, or COP15, in Campo Grande, Brazil, marking a pivotal moment for a historically overlooked environmental crisis."
