Abstract The Mekong River, a global freshwater biodiversity hotspot, has suffered from intensive barrier construction, resulting in major challenges safeguarding its fauna. Here, we provide comprehensive evaluation of the impacts river barriers on distribution 1,032 fish species Basin. Our analysis revealed that 93% suffer habitat fragmentation, and with larger range requirements experienced higher fragmentation impacts. Sub-basins along main channel Lower had high values richness but relatively Across all migration types, potamodromous worst status (Fragmentation Index, 42.56 [95% CI, 36.95–46.05]), followed by catadromous fish. Among IUCN conservation categories, Critically Endangered highest index (33.34 [12.53–46.40]). small dams sluice gates contribute more to than large dams.
