Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Delturus parahybae faces severe threats from dam construction and water diversions that fragment its riverine habitat and alter natural flow regimes essential for its survival. Agricultural runoff and urban pollution from expanding settlements along the Paraíba do Sul River basin have degraded water quality, while sedimentation from deforestation reduces suitable spawning and feeding areas. The species' restricted range within southeastern Brazil's heavily developed river systems makes it particularly vulnerable to these cumulative anthropogenic pressures.
Habitat
This freshwater fish species inhabits the Paraíba do Sul River basin in southeastern Brazil, preferring clear, well-oxygenated waters with rocky or sandy substrates. It typically occurs in medium to large rivers with moderate to fast currents, often associated with areas containing fallen logs and aquatic vegetation that provide shelter and feeding opportunities.
