(Carps) > Cyprinidae
(Minnows or carps) > Labeoninae
Etymology: Labeo: Latin, labeo = one who has large lips (Ref. 45335); degeni: named after Mr. Degen who painted the aquarelle of this species in Boulenger's original desription..
More on author: Boulenger.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical; 5°N - 10°S
Africa: lectotype and paralectotype locality of Labeo degeni: "Kinshasa, near the rapids" (Ref. 26192). Distribution of this species in the Congo basin as given in Ref. 26192, with reports from the marine lower Congo, Kasai, Ubangi, Wagenia Falls and upper Lualaba, is questionable.

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00394 - 0.01927), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Moderate to high vulnerability (53 of 100).
