|Population:||This species is widespread and common.|
|Habitat and Ecology:||Clarias ngamensis is a demersal, potamodromous species. This species prefers vegetated habitats in swamps and estuaries and the lower reaches of rivers. It lives over muddy bottoms in swampy areas and feeds on snails (Konings 1990). This species prefers vegetated habitats. Feeding habits overlap considerably with the sharptooth catfish (Clarias gariepinus). Important foods are molluscs, terrestrial and aquatic insects, shrimps, crabs and fish. Hard-shelled foods such as mussels are crushed before they are swallowed. It reportedly packhunts together with the sharptooth catfish in the Okavango Delta. Clarias ngamensis breeds during the summer rainy season when it moves into shallow flooded drainage channels to spawn.|
|Use and Trade:||This species is harvested for human consumption.|
|Major Threat(s):||Clarias ngamensis is used in aquaculture, and in eastern Africa it is threatened with habitat degradation.|
|Conservation Actions:||The species distribution falls within some reserves in southern Africa. Population trends should be monitored, and habitat conservation may be required.|
