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.
Hoplias gronovii is a species of characiform fish native to French Guiana. Very little information is available on the species, and the validity of the species has been questioned by some authors. No introductions of H. gronovii have been reported, so history of invasiveness is uncertain. It is listed as a prohibited species by the State of Florida. Climate match is low throughout the contiguous United States. Because of the lack of introduction history and questions about the validity of the species, certainty of the assessment is low. Overall risk posed by H. gronovii is classified as “Uncertain”.
