Ecological Risk Screening Summary - Tridentopsis pearsoni (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.

Tridentopsis pearsoni is a species of parasitic catfish native to the Upper Amazon River basin (Bolivia, Brazil, Colombia, and Ecuador). There is little information on the biology of the fish. There have been no reports of the species outside of its native range. Several U.S. States prohibit or restrict the possession, transport, or trade of this species along with other members of the family Trichomycteridae. History of invasiveness is uncertain. Climate match to the contiguous United States is low. However, Florida has a medium to high climate match moving from north to south and the southernmost tip of Louisiana has a medium match. Certainty of assessment is low due to lack of information. The overall risk assessment category for this species is Uncertain.
