Africa: widespread from the middle and lower Zambezi south to the Phongolo system (Ref. 7248, 52193). Also known from the Luachimo River, middle Congo River basin, in Angola (Ref. 11970, 120641). Reported as Labeobarbus cf. marequensis from the lower Congo (Ref. 94750); needs confirmation.
非洲: 廣泛地分佈了從尚比西河中下游南至澎哥洛河流域。

Prefers flowing waters of perennial rivers; uncommon in dams (Ref. 52193). It feeds on a wide variety of food items, primarily algae and aquatic insect larvae; also small fishes, snails, freshwater mussels and drifting organisms such as beetles and ants (Ref. 52193). Breeds in spring and summer, migrating upstream in rain swollen rivers to spawn in rapids; males mature at 70 mm FL, females mature at 280 mm FL (Ref. 52193). Occurs with the bushveld smallscale yellowfish, Labeobarbus polylepis in southern Limpopo tributaries (Ref. 7248, 52193).
偏爱终年不断之河川的流动水域。 罕见在水坝中。 吃各式各样的食物, 主要地藻类与水生的昆虫幼生; 也吃小鱼, 蜗牛, 淡水贻贝而且漂流生物例如甲虫与蚂蚁。 繁殖于春天与夏天, 在雨水倾注的河中向上游移动产卵于急流中。 雄性在 70 公分 FL 时成熟,雌性在 28 公分 FL 时成熟。 在许多南非德兰士瓦河中与小规模 yellowfish 生存在一起。 (参考文献 7248)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00201 - 0.00949), b=3.10 (2.90 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.2 ±0.44 se; based on food items.
回复力 (Ref.

Fishing Vulnerability (Ref.
