Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 2; Mjukstrålar i ryggfenan (totalt) : 7; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 6 - 8. Diagnosis: head broad (width at least 2/3 of length); snout length less than 0.9 times head width; hind margin of adipose fin nearly straight; premaxillary dentition forming (in adults) 2 well separated, kidney-shaped plates; maxillary barbels never black and reaching at least to hind margin of eye; 8-11 (usually 9 or 10) gill rakers on lower limb of first gill arch; palatine membrane bilobed (with a large and a smaller lobe); dorsal margin of cleithral process broad and flat (visible only in adults)(Ref. 57126).

Commonly occurs in running water, lakes and submerged vegetation in the Sudd, rare in fringing vegetation. Feeds on the bottom on mud, debris, insects, notably chironomid larvae and mollusks. Gravid fish are recorded throughout the year with a peak in the dry season (Ref. 28714).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00221 - 0.01248), b=3.09 (2.87 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.1 ±0.41 se; based on food items.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).
