Ecological Risk Screening Summary - Potamotrygon tigrina (a stingray, no common name) - Uncertain Risk

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.

Potamotrygon tigrina is a freshwater stingray found in the upper Amazon basin in Peru. The history of invasiveness is classified as “no known nonnative population.” Freshwater stingrays from South America have become increasingly popular for display in public aquaria in the United States and Canada. P. tigrina is a popular pet in Asia. P. tigrina has been transported beyond its native range due to commercial trade for at least 13 years with no found evidence of establishment in the wild outside of its native range. However, there is no information on the volume of this species in trade which precludes listing the history of invasiveness as low. This species is regulated in some States. The climate match was low. There were no areas of high or medium match in the contiguous United States. The certainty of assessment is low. The overall risk assessment category is uncertain.
