Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2007
Date Assessed: 2007-03-01

Reviewer(s): Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Unit)
Widespread and common in suitable habitats within much of its southern range in Mpumalanga, Swaziland and KwaZulu-Natal. Although populations in northern parts of its range in the Limpopo River appear to have declined it does not qualify for any of the endangered criteria.

Habitat and Ecology [top]

Habitat and Ecology:Found in sandy habitats in larger streams and rivers. The species buries itself in the sand substrate and forages on drift invertebrates and those in the substrate.

Threats [top]

Major Threat(s): Habitat degradation. Sedimentation of habitats from varied forestry and agricultural activities affect this and all other Chiloglanis species. Chemical pollution from industries, large towns and agriculture also locally affect Chiloglanis. Require permanent flows and have disappeared from the Letaba River.

Conservation Actions [top]

Conservation Actions: River health programmes aimed at improving the conservation of aquatic habitats should be supported. Widespread establishment of conservancies may also help in conserving aquatic habitats.
