Pimelodus halisodous

Unknown

Overview

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

Pimelodus halisodous faces significant pressure from dam construction and river regulation throughout its range in South American river systems. Overfishing and habitat degradation from agricultural runoff and urban development have further reduced population stability. The species' migratory behavior makes it particularly vulnerable to river fragmentation, as dams block essential spawning routes.

Threat summary

Habitat

This catfish species inhabits large river systems and tributaries in South America, preferring deep channels with moderate to strong currents. It typically occurs in areas with rocky or sandy substrates and requires free-flowing waters for successful reproduction and migration.
