Share of freshwater fish species threatened with extinction (IUCN Red List)
Percent of assessed freshwater fish species that are threatened with extinction (Critically Endangered, Endangered, or Vulnerable) in each country.

Key Insights
- •Freshwater fish threat levels are often highest in regions facing rapid water infrastructure expansion, pollution, and habitat conversion.
- •Small island states may show extreme percentages due to small species lists and endemism.
- •Even countries with strong environmental regulation can have notable threatened shares where rivers are heavily modified or fragmented.
- •Comparisons are most meaningful across countries with similar assessment coverage and freshwater fish diversity.

About This Statistic
This statistic shows the share of assessed freshwater fish species in a country that are classified as Threatened on the IUCN Red List (Critically Endangered, Endangered, or Vulnerable). It highlights how pressures such as habitat fragmentation (dams), water pollution, invasive species, overfishing, and water abstraction are affecting freshwater biodiversity—often one of the most imperiled and least visible parts of nature.
Values are derived from IUCN’s Red List spatial and assessment data by counting freshwater-dependent fish species whose ranges overlap a country and calculating the percentage that are listed as threatened. Because knowledge and assessment coverage vary across taxa and regions, this metric is best interpreted as a comparable indicator of biodiversity risk rather than an absolute census of all species present.
