Justification:
The species is known from only three locations (Sabie-Sand River, Mozambique coastal lakes and Lake Sodwana), with an area of occupancy less than 500 km². The lake record is considered as dubious and needs verification. The major threat of habitat degradation (reduced water quality, increased sedimentation, loss of pools) is increasing. The species was previously assessed, using the 1994 Red List criteria, as LD/cd; this uplisting is partially genuine because of habitat degradation, but also a result of changes in criteria.

Habitat and Ecology
[top]
| Habitat and Ecology: |
Main river channels and backwaters of larger rivers and coastal lakes.
|
| Systems: |
Freshwater |
| Major Threat(s): |
Decreased water quality and quantity in the Kruger Park region through a variety of human impacts e.g., forestry in upper catchments, human settlements, industrial effluents.

Conservation Actions
[top]
| Conservation Actions: |
Improvement of water quality and quantities through river health programmes is in place. These programmes need to continue and feed back into conservation action plans. Introductions into dams in the Sabie catchment has been done successfully and further introductions will help the species' conservation status. Exploratory surveys in Mozambique are needed.
