Sartor tucuruiensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Sartor tucuruiensis faces severe threats from hydroelectric dam construction and operation in the Tocantins River basin, particularly the Tucuruí Dam which has dramatically altered water flow patterns and sediment deposition. The species' specialized habitat requirements make it extremely vulnerable to changes in river hydrology, with dam-induced flow modifications disrupting the specific current and substrate conditions this endemic fish requires for feeding and reproduction.
Habitat
This endemic fish species inhabits fast-flowing sections of the Tocantins River system in Brazil, particularly areas with rocky substrates and strong currents. It requires specific hydrological conditions found in rapids and cascades of the middle Tocantins River basin.
