A new assessment released by the International Union for Conservation of Nature (IUCN) reveals that numerous species of fish worldwide are at risk of extinction.

The assessment was a formal update to the IUCN’s Red List of Threatened Species, the world’s most comprehensive information source on the extinction risk of animals and plants.

This was the first exhaustive analysis of freshwater fish by the IUCN, and their published findings showed that over 3,000 species out of 15,000 species of fish were at risk. In other words, over a fifth of the world’s freshwater fish species are on their way to extinction.
