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 maracaya is a South American, trichomycterid catfish found only in an unnamed streamlet that is a tributary of the rio Pardo system in Southeastern Brazil. T. maracaya inhabits the limonite rocky bottom of the streamlet and hides among the plant litter. It is a nocturnal, benthic forager, feeding on immature aquatic insects and small tadpoles. Trichomycterus maracaya is regulated in multiple States. There have been no reports of this fish outside of its native range. Therefore, the history of invasiveness is classified as No Known Nonnative Population. The overall climate match is Low. The only areas of medium and high match were found in peninsular Florida. The certainty of assessment is Low due to a general lack of information. The overall risk for this species is uncertain.
