Pseudotocinclus tietensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pseudotocinclus tietensis faces severe pressure from habitat degradation in its restricted range within the Tietê River basin of São Paulo state, Brazil. Agricultural expansion and urban development have significantly altered riparian zones and water quality in the region. Dam construction and water extraction for irrigation have modified natural flow regimes, while sedimentation from deforestation upstream threatens the rocky substrates this armored catfish requires for feeding and reproduction.
Habitat
This small armored catfish inhabits rocky substrates in clear, fast-flowing streams and tributaries within the upper Tietê River system in São Paulo state, Brazil. It prefers well-oxygenated waters with moderate to strong currents where it can graze on algae and biofilm from rock surfaces.
