Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Magdalena River prochilodus faces severe population declines primarily due to extensive dam construction throughout the Magdalena-Cauca river system, which fragments populations and blocks critical spawning migrations. Overfishing pressure has intensified as this commercially important species becomes increasingly scarce, while agricultural runoff and industrial pollution degrade water quality in its remaining habitat. Deforestation in the watershed has increased sedimentation and altered natural flow patterns essential for reproduction.
Habitat
This freshwater fish inhabits the main channels and tributaries of the Magdalena and Cauca river systems in Colombia, preferring areas with moderate to strong currents and rocky or sandy substrates. The species requires free-flowing rivers for spawning migrations and depends on floodplain connectivity during reproductive cycles.
