Trichomycterus rubbioli

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Trichomycterus rubbioli faces severe threats from habitat degradation in its restricted range within Brazilian freshwater systems. Agricultural expansion and urban development have led to water pollution and sedimentation of the clear, fast-flowing streams this endemic catfish requires. Dam construction and water extraction for irrigation further fragment and alter the hydrological conditions essential for the species' survival.

Threat summary

Habitat

This endemic Brazilian catfish inhabits clear, fast-flowing freshwater streams and rivers with rocky substrates in highland regions. The species requires well-oxygenated waters with specific temperature and flow regimes typical of montane aquatic ecosystems.
