What is it about?
Many fish species migrate long distances through river systems to breed, feed, and complete their life cycles. This study examines the conservation status of migratory fish in one of South America's largest river basins, assessing whether existing protected areas are sufficient to safeguard these species. Our analysis shows critical gaps in protection along migratory routes, and we conclude that the creation of new protected areas is essential to ensure the survival of these ecologically and economically important fish.

Why is it important?
Migratory fish are vital components of South American river ecosystems and support important fisheries that millions of people depend upon. Yet they remain poorly protected because their long migrations cross multiple jurisdictions and land uses. This study provides spatial evidence of where new protected areas are most urgently needed to close the gaps in conservation coverage for these wide-ranging species.
Perspectives
The plight of migratory fish in South American rivers is something I care deeply about. These species swim hundreds or thousands of kilometers, yet face fragmented and inadequate protection throughout their range. I hope this study motivates governments and conservation organizations to prioritize new protected areas specifically designed for the needs of migratory fish.
