In September 2016, the International Union for Conservation of Nature (IUCN) listed 1245 vulnerable fish species.
Additionally 3191 fish species (21% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status.
As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.
