Clarias submarginatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Clarias submarginatus faces severe pressure from habitat degradation due to agricultural expansion and water pollution in its native river systems. Dam construction and water extraction for irrigation have significantly altered natural flow regimes, fragmenting populations and reducing suitable breeding habitats. Overfishing and the introduction of non-native fish species have further compromised remaining populations through direct exploitation and competitive displacement.
Habitat
This catfish species inhabits freshwater river systems and associated wetlands in sub-Saharan Africa, preferring slow-moving waters with muddy substrates and abundant vegetation. It typically occurs in floodplain areas and seasonal pools that provide critical spawning and nursery habitats.
