Notes

It must be noted that Enteromius treurensis formerly belonged to the genus Barbus, but following the work of Yang et al. (2015), the genus Enteromius was expanded to include additional species resulting in the renaming of the Enteromius treurensis (Skelton 2016).

Freshwater (=Inland waters)

It occurs in cool, clear flowing mountain streams with loose rock substrate and the riparian zone consisting mainly of grass and shrubs. This species is predominantly found in small pools (3 m to 4 m in diameter and 1.2 m to 2.3 m deep), as well as in runs (Kleynhans 1984, 1996; Skelton 1987). Where they occur in runs it is primarily behind rocks to avoid velocity of the current. The velocity in the pools range from 0.1 m sec-1 to 0.28 m sec-1 with an average depth of 1.8 m. It feeds mainly on aquatic invertebrates, but also ingests filamentous algae and can be considered a facultative feeder (Kleynhans 1987). This species breeds during October to November and can be regarded as a total spawner. Males and females develop small nuptial tubercles on the head in the breeding season. Fecundity increases with size and age from about 350 ova in a female (65 mm TL) to 2040 ova (108 mm TL) (Kleynhans 1984).
