Overview

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

The Conchos River sucker faces severe habitat degradation from water diversions and dam construction throughout its native range in the Río Conchos basin of Chihuahua, Mexico. Agricultural water extraction has dramatically reduced river flows, while introduced species compete for resources and alter ecosystem dynamics. Mining activities and urban development have further degraded water quality through sedimentation and pollution.

Threat summary

Habitat

This endemic sucker inhabits the clear, flowing waters of the Río Conchos basin in Chihuahua, Mexico, preferring rocky substrates and moderate currents typical of desert river systems. The species requires well-oxygenated water with stable flows for successful reproduction and feeding.
