Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal soft rays: 59 - 73. Diagnosis: 13-16 gill rakers on lower limb of first gill arch; 59-73 branched anal-fin rays; eyes positioned dorso-laterally; adipose fin always absent; often with a post-occipital hump, a character also sometimes found in Schilbe intermedius whose head profile is extremely variable (Ref. 57127). Coloration: sides more or less silvery in juveniles; head and postcephalic area irregularly mottled (Ref. 57127). In adults, head and back, as well as all fin-bases, dark brown; sides yellowish or whitish; anal fin sometimes black-edged (Ref. 57127).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00255 - 0.01239), b=3.03 (2.84 - 3.22), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=1.30; tmax=3; assuming fec > 10,000).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
Price category (Ref. 80766):   Unknown.
