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 fassli is a freshwater parasitic catfish from South America. It has not been reported outside of its native range in western Bolivia and southern Peru. Due to lack of introduction history, the history of invasiveness is uncertain. This species has a low overall
climate match with the contiguous United States, with medium match occurring only in parts of peninsular Florida. Due to the lack of information about potential introductions, the certainty of assessment is low. The overall risk assessment category for T. fassli is uncertain.
