Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Pimelodus grosskopfii faces severe threats from dam construction and water diversions that fragment its riverine habitat and alter natural flow regimes. Agricultural runoff and urban pollution have degraded water quality in its limited range, while overfishing pressure has reduced population numbers. The species' restricted distribution in the Paraná River basin makes it particularly vulnerable to localized environmental changes.
Habitat
This catfish species inhabits the main channels and tributaries of the Paraná River system in South America, preferring areas with moderate to strong currents and rocky or sandy substrates. It typically occurs in deeper waters of large rivers where it feeds on smaller fish and aquatic invertebrates.
