Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 1; Taggstrålar i analfenan 0. Diagnosis: body short and robust, its depth 4.2-5.2 times in standard length; head as long as broad, dorsal surface rough; maxillary barbels non-membranous and unbranched, up to 2 times longer than head; mandibular barbels with short, simple ramifications; humeral process long and pointed; 1st dorsal-fin spine smooth on anterior and posterior margins; 2nd dorsal fin with 10-14 rays; pectoral-fin spines more strongly denticulate on inner than on outer margin; caudal fin deeply forked, with upper lobe slightly longer than lower (Ref. 57223).
Coloration: general colour pattern similar to that of M. niloticus, but there seem to be fewer dots on dorsal fins (Ref. 57223).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00303 - 0.02871), b=3.05 (2.80 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
