Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(i,ii,iv,v)+2ab(i,ii,iv,v) ver 3.1
Year Published: 2007
Date Assessed: 2007-03-01
Assessor(s): Engelbrecht, J. & Bills, R.
Reviewer(s): Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Unit)
Justification:
The population has a restricted geographic range and meets the thresholds for Endangered under criterion B. There are only two known viable populations - in the upper catchments of the Blyde River system. Despite the two sites being proclaimed National Heritage sites to protect the species there are still serious potential threats from introduced alien fishes (Oncorhynchus mykiss, Salmo trutta and Micropterus dolomieu). The species qualifies as Endangered.
History:
1994 Vulnerable (Groombridge 1994)
1990 Vulnerable (IUCN 1990)
1988 Vulnerable (IUCN Conservation Monitoring Centre 1988)
1986 Endangered (IUCN Conservation Monitoring Centre 1986)

Major Threat(s): Alien fish predators are the major impact on this species particularly small mouth bass (Micropterus dolomieu). Extirpated from the type locality.

Conservation Actions [top]

Conservation Actions: Reintroduced successfully into the Treur River (type locality). Both areas of occupancy have been proclaimed National Hertiage sites to protect the species.
