Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
The White Catfish, Ameiurus catus is a freshwater catfish native to the Atlantic Coast of the United States from New York to Florida. The history of invasiveness is classified as Data Deficient. This species has been introduced widely outside the native range for commercial and gamefish purposes, many of which have resulted in established populations. Most introductions have occurred within the contiguous United States. Ameiurus catus are a restricted species in Arizona. Individuals have also been reported in the United Kingdom and the Philippines, but these populations are not known to be established. Some native fish species have declined after the introduction of A. catus; however, those declines were not shown to be the direct results of the introduction. The overall climate match for the contiguous United States was High. All individual States received High individual Climate 6 scores. The certainty of assessment is Low. The overall risk assessment category for Ameiurus catus is Uncertain.
