Ecological Risk Screening Summary - Trichomycterus stellatus (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 stellatus is a small catfish endemic to streams in the Magdalena-Cauca River basin in Colombia. Information on the biology of Trichomycterus stellatus is not widely available. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. This species has not been reported as introduced outside of its native range, so history of invasiveness is uncertain. Certainty of this assessment is low due to lack of information on impacts of introduction. The climate match for T. stellatus is low overall for the contiguous United States, with only a small area of medium match in northwestern Washington. The overall risk posed by this species is uncertain.
