Ecological Risk Screening Summary - Hoplias microcephalus (a fish, 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.

Hoplias microcephalus is a species of characiform fish native to the São Francisco River basin in Brazil. Very little information is available on the species, although it is known to be a piscivore that lives in lake environments. No introductions of H. microcephalus have been reported. It is listed as a prohibited species in the State of Florida. Climate match to the contiguous United States is low overall, with medium matches in southwestern Florida and southern Texas. Because of the lack of introduction history, history of invasiveness is uncertain and certainty of the assessment is low. Overall risk posed by H. microcephalus is classified as “Uncertain”.
