Teleostei (teleosts) > Cypriniformes (Carps) > Cyprinidae (Minnows or carps) > Labeoninae
Etymology: Labeo: Latin, labeo = one who has large lips (Ref. 45335).
Eponymy: Rosa Holub née Hoff (1865–1958) was the Viennese wife of Czech physician, cartographer and ethnographer Emil Holub (1847–1902), who collected the type. She participated in his later African explorations (1883–1886). (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 14 - 15; Anal spines: 0; Anal soft rays: 8.

Found in the warmer reaches of rivers, particularly in sandy stretches of larger perennial and intermittent rivers (Ref. 1440, 52193). It feeds on detritus, algae, and small invertebrates (Ref. 52193). An active fish, leaps at barriers when migrating upstream in swollen rivers to breed in summer (Ref. 7248, 52193). Sexually mature at 15 cm TL (Ref. 7248).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00305 - 0.02858), b=3.01 (2.76 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.4 ±0.18 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).

Price category (Ref. 80766): Unknown.
