The National Red List of Sri Lanka: Assessment of the Threat Status of the Freshwater Fishes of Sri Lanka 2020

A total of 61 endemic species were assessed. Of these, 12 point endemic species were listed as Critically Endangered (CR); 24 range-restricted species were Endangered (EN); and nine species were Vulnerable (VU). In addition, five species were Near Threatened (NT); two were listed as Data Deficient (DD); and the remaining were listed as Least Concern (LC). This means that 74% — nearly three quarters — of the freshwater fish endemic to Sri Lanka were found to be Threatened with extinction. Thirty-six native species were also assessed and of these, only eight species were listed as Threatened.
