💧 325 migratory freshwater fish species have been identified as needing coordinated international conservation action, with 97% of those already listed under the Convention on Migratory Species being at risk of extinction.
💧 Since 1970, populations of migratory freshwater megafish in Asia have declined by over 95%, with species like the Mekong giant catfish critically endangered due to dams and overfishing.
💧 The longest freshwater fish migration recorded is over 6,000 miles by the dorado (gilded catfish) in the Amazon, but altered river flows, barriers, and overfishing are disrupting these journeys.
💧 Key solutions include keeping rivers free-flowing, reconnecting fragmented rivers, improving fisheries management, protecting floodplains, and managing rivers as connected ecological systems across borders.
