Short description Morphology | Morphometrics

Lateral line running along middle of the flank and the caudal peduncle. Flap of skin in front of upper lip. Jaws with horny cutting ridges. Barbels hidden. Olivaceous dorsally, light or creamy ventrally. Dorsal, anal and pelvic fins often orange-tipped (Ref. 34290).

Biology     Glossary (e.g. epibenthic)

Anadromous species; ascending both large rivers and streams during floods and spawning in floodwater pools or inundated grasses at margins of rivers (Ref. 105018). Upstream migration at beginning of rains (Ref. 36900) in fairly compact shoals (Ref. 52083). Permanent river populations exist (Ref. 52083). Lake Victoria: in shallow, inshore waters and influent rivers (Ref. 34291). Lake Kyoga: in open waters away from water-lily zone (Ref. 4903). Specialized feeder on epilithic and epiphytic algae (Ref. 12526). Also feeds on rotifers growing on the body of other fishes (Ref. 34291). Caught with weirs and in baskets (Ref. 4967). Oviparous (Ref. 205).

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=0.01000 (0.00517 - 0.01933), b=3.07 (2.91 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.4   ±0.22 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):  Moderate vulnerability (40 of 100).
Price category (Ref. 80766):   Unknown.
