Condition / length-weight relationship : Paxton et al., 2002 .
Current distribution known : endemic to the Olifants-Doring River System in the Western and Northern Cape provinces of South Africa. There is evidence that the species has been extirpated from the Olifants River as, despite sampling efforts, no specimen have been collected from the Olifants River since the mid-1980s. The remaining population is therefore confined to remnant subpopulations in the Doring River main stream and isolated tributaries of the Doring River namely the Oorlogskloof-Koebee, Gif, Kransgat, Biedouw, Tra-Tra, and Matjies rivers where they have been recorded in the last five years (Van der Walt 2014. The Oorlogskloof-Koebee River in the Oorlogskloof Nature Reserve is home to the only remaining viable and recruiting subpopulation of this species as it provides suitable spawning habitat in the absence of predatory alien fish species. Due to very low numbers of adult fish and predation by alien invasive fish species, recruitment contributions from the remainder of the remnant subpopulations in the catchment are not expected to be significan .
