Prochilodus britskii

Unknown

Overview

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

Prochilodus britskii faces severe pressure from dam construction across the Paraná River basin, which fragments its migratory routes essential for spawning. Overfishing in both commercial and subsistence fisheries has significantly reduced population numbers, while water pollution from agricultural runoff and urban discharge degrades the water quality of its riverine habitat. Climate-driven changes in seasonal flooding patterns further disrupt the species' reproductive cycles and feeding behavior.

Threat summary

Habitat

Prochilodus britskii inhabits the freshwater river systems of the Paraná River basin in South America, particularly favoring areas with moderate to strong currents and rocky or sandy substrates. The species requires access to both main river channels for feeding and tributary systems for spawning migrations.
