The Amazon Forgotten Fishes report explores the extraordinary diversity of the Amazon River’s more than 2,700 freshwater fish species and the connected rivers, floodplains, and wetlands they depend on to survive. The report highlights how freshwater fishes support ecosystems, food security, and livelihoods across the basin while facing mounting threats from habitat fragmentation, dams, pollution, overfishing, and climate change. It also outlines practical solutions, including protecting free-flowing rivers, restoring connectivity, improving water quality, strengthening community-led fisheries management, and advancing basin-wide conservation efforts to ensure a thriving future for Amazon freshwater ecosystems.
