Ecological Risk Screening Summary - Trichomycterus stawiarski (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 stawiarski is a catfish native to Brazil. This species lives in small creeks and rivers with fast-moving water and rocky substrate, and feeds on benthic invertebrates. There have been no documented introductions of this species outside of its native range. History of invasiveness is uncertain. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. The certainty of this assessment low due to lack of information. T. stawiarski has a medium overall climate match with the contiguous United States, with a high match along the Gulf Coast from eastern Texas to western Florida. The overall risk posed by this species is uncertain.
