Duri dubur: 0; Sirip dubur lunak: 13 - 18. Diagnosis: multicuspid teeth set in two rows and not overlapping the jaws when the mouth is closed; teeth stout, not compressed; eyes with well-developed vertical adipose lids; slender body; head not flattened (Ref. 28714). Dorsal fin origin at about same level as pelvic fin insertion (Ref. 2880, 80290, 81279), about halfway between caudal fin and snout (Ref. 28714). Fronto-parietal fontanel absent in adults, sometimes pore-like in juveniles, disappearing with growth; sexual dimorphism affecting anal fin shape; 24-34 lateral line scales; 5.5 scales between lateral line and dorsal fin; 10-15 anal fin branched rays; 14-20 gill rakers on lower limb of first gill arch; 8 teeth in outer premaxillary row (Ref. 2880, 80290, 81279). Snout short, more than 3x head length; head length/snout length 3.6-4.3; 10-11.5 predorsal scales; flanks without lateral band; adults medium-sized (Ref. 80290).

Inhabits rivers, lakes, irrigation canals and fringing vegetation; feeds on zooplankton, Caridina, insects, snails and vegetation (Ref. 28714). Dwarf populations are described in lake basins: Lake Turkana, B. n. nana Pellegrin, 1935 and Lake Chad, B. n. dageti Blache and Miton, 1960 (see Ref. 2880).

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=0.01096 (0.00865 - 0.01390), b=3.00 (2.95 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 2.5 ±0.2 se; based on diet studies.

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (K=0.41-0.92; tm=1; Fec < 1,000).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).

kategori harga (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 147 [53, 366] mg/100g; Iron = 2.12 [1.01, 4.98] mg/100g; Protein = 18.7 [16.7, 21.0] %; Omega3 = 0.503 [0.186, 1.390] g/100g; Selenium = 45 [19, 123] μg/100g; VitaminA = 42.5 [14.9, 114.6] μg/100g; Zinc = 2.38 [1.62, 3.53] mg/100g (wet weight);
