Ecological Risk Screening Summary - Trichomycterus alterus (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 alterus is an insectivorous trichomycterid catfish native to Argentina. T. alterus has a medium climate match to the contiguous United States. It has not been introduced outside of its native range. Without being able to observe introductions in other parts of the world, it is impossible to postulate the potential impacts of introduction of T. alterus to the U.S. The Florida Fish and Wildlife Conservation Commission has listed the parasitic catfish T. alterus as a prohibited species. The overall risk posed by this species is uncertain.
