Ecological Risk Screening Summary - Acestrorhynchus pantaneiro - Uncertain Risk

Acestrorhynchus pantaneiro is a freshwater fish species native to South America. This species is fished commercially and may appear in the aquarium trade. A. pantaneiro feeds on other fish and reproduces by multiple spawning. In the Patos Lagoon in Brazil, introduced A. pantaneiro may compete with native piscivorous fishes for food, as shown in one dietary study; however, there is no evidence that A. pantaneiro has negatively impacted populations of native piscivores in that system. More research is needed to fully understand the impacts from introductions of this species; absence of this research makes the certainty of this assessment low. Climate match with the contiguous United States is medium. Overall risk posed by this species is uncertain.

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.
