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.
Payara (Hydrolycus tatauaia) is a freshwater fish species native to South America that is found in the Amazon and upper Orinoco River basins and rivers of Guyana. Information on the biology of H. tatauaia is not widely available. No introductions of the species have been reported, although it is present in the aquarium trade in the United States. More information is needed to understand the impacts from potential introductions; absence of this information makes the certainty of this assessment low. Climate match with the contiguous United States is low. Overall risk posed by this species is uncertain.
