Algansea lacustris
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Algansea lacustris 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 lake systems. Introduced exotic fish species compete directly for resources and alter the ecosystem dynamics that this endemic species depends upon. Pollution from agricultural runoff and urban development further degrades water quality in the remaining habitat fragments.
Habitat
This endemic Mexican fish inhabits shallow, vegetated areas of lakes and associated tributaries in the central Mexican plateau. It prefers areas with moderate water flow and abundant aquatic vegetation that provide both feeding opportunities and spawning habitat.
