Cnesterodon carnegiei
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Cnesterodon carnegiei faces severe pressure from habitat degradation in Uruguay's coastal wetlands, where urban development and agricultural expansion have fragmented its limited freshwater systems. Water pollution from agricultural runoff and urban discharge has compromised water quality in the small streams and lagoons this species depends upon. The introduction of non-native fish species has created additional competitive pressure and potential predation threats in its restricted range.
Habitat
This small freshwater fish inhabits shallow coastal streams, lagoons, and wetlands along Uruguay's Atlantic coast. It prefers areas with dense aquatic vegetation and slow-moving or still waters with sandy or muddy substrates.
