Short description Morfologia | Morfometria

Body covered with very big scales; dorsal and anal fins almost fused with the caudal fin; 2 barbels at the extremity of the lower jaw; adult silvery, juvenile with blue glints and a yellow-orange bar (Ref. 12225).

Biologia     Glossario (es. epibenthic)

Is an omnivore with a tendency to feed on fish at the surface. The superior position of the mouth allows it to capture its prey while swimming from below. Also jumps out of the water to feed on large insects (Coleoptera; Ref. 27548). It is capable of adapting to environments with low oxygen levels (Ref. 12225).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

The male carries eggs, larvae and early juveniles (alevinos) in his mouth (Ref. 1672), which lasts for nearly six weeks (Ref. 102836).

Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7656   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00141 - 0.00932), b=3.13 (2.90 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.48 se; based on food items.
Resilienza (Ref. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
