Ecological Risk Screening Summary - Corroncho (Pterygoplichthys punctatus) - 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.

Corroncho (Pterygoplichthys punctatus) is a freshwater armored catfish found in Bolivia, Brazil, Ecuador, and Peru. Limited information is known about this species but it is present in the aquarium trade. No introductions of P. punctatus have been recorded. Therefore, history of invasiveness is classified as No Known Nonnative Population. The climate match for the contiguous United States is low. Areas of medium math were found along the Gulf Coast in and Peninsular Florida; the only area of high match was found in southern Florida. The certainty of assessment is low due to a lack of information. The overall risk assessment for Pterygoplichthys punctatus is Uncertain.
