Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 5; Anal spines: 0; Anal soft rays: 67 - 87. Diagnosis: 67-87 anal-fin rays; 50-60 thin and flexible gill rakers on lower limb of first gill arch; 4 pairs of well developed barbels; small, spineless dorsal fin with 5 branched rays; jaws and palatine bones entirely without teeth; (Ref. 57127). Coloration: in live fish as well as in preserved specimens, the coloration resembles that of juveniles of Schilbe intermedius: head and back brown; dark band along lateral line, another above anal fin, and a third on anal-fin margin; other fins slightly mottled (Ref. 57127).

In the Sudd, they occur beneath fringing Eichornia. Stomach of fish examined contained zooplankton, chironomids and debris (Ref. 28714). Oviparous, eggs are unguarded (Ref. 205). Max. size 175 mm total length (Ref. 3570).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00646 (0.00337 - 0.01237), b=2.99 (2.82 - 3.16), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 2.9 ±0.34 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100) .

Price category (Ref. 80766): Unknown.
