List of data deficient fishes

In September 2016, the International Union for Conservation of Nature (IUCN) listed 3191 data deficient fish species.[1] A data deficient species is one which has been categorized by the IUCN as offering insufficient information for a proper assessment of conservation status to be made. Of all evaluated fish species, 21% are listed as data deficient. The IUCN also lists 12 fish subspecies as data deficient.
