Algansea barbata

Declining

Overview

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

Algansea barbata faces severe population decline primarily due to water extraction and diversion for agricultural and urban use, which has dramatically reduced water levels in its native river systems. Habitat degradation from pollution, sedimentation, and the introduction of non-native fish species has further compromised the remaining suitable environments. The species' restricted range in central Mexican river basins makes it particularly vulnerable to localized environmental changes and human activities.

Threat summary

Habitat

This freshwater fish inhabits clear, flowing rivers and streams in the central Mexican highlands, particularly in the Lerma River basin. It prefers well-oxygenated waters with rocky or sandy substrates and moderate current flow.
