Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 0; Spine anali: 0; Raggi anali molli: 51 - 68. Diagnosis: adipose fin present; inner side of pectoral spine feebly serrated, with small to very small serrations; 51-68 soft anal fin rays; vomerine teeth usually absent; a dark triangular blotch at base of caudal fin (Ref. 43912, 81643).

Confined to large and moderate rivers; sometimes penetrates into estuaries; gregarious schooling species, such schools probably an important prey for several larger carnivorous species (Ref. 43912). Oviparous, eggs are unguarded (Ref. 205). Maximum TL reported 85 mm (Ref. 43912).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00269 - 0.01291), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
