Ecological Risk Screening Summary - Trichomycterus mirissumba (a catfish, 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.

Trichomycterus mirissumba is a South American, trichomycterid catfish found in the Preto River of the Paraíba do Sul River basin in Brazil. T. mirissumba is regulated in multiple States. There have been no reports of introductions of this fish outside of its native range, so the history of invasiveness is classified as No Known Nonnative Population. In addition, biological information about Trichomycterus mirissumba was limited, therefore; the certainty of this assessment is Low. The overall climate match for this species was Low. Peninsular Florida had a medium match. The overall risk for this species is Uncertain.
