Biologi     Ordlista (t.ex. epibenthic)

Inhabits shallow inshore areas close to vegetation (Ref. 4983). Lake Victoria populations are largely omnivorous, larval insects and small crustaceans predominate in the diet (Ref. 558).

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=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
