Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 12 - 14; Spine anali: 0; Raggi anali molli: 8 - 9; Vertebre: 40 - 43. Diagnosis: High lateral line scale count, 31-40 scales on lateral line; long, robust barbelsof equal length; and enlarged, molariform pharyngeal teeth (Ref. 75045).

Inhabits inshore areas of the lake, but ascends rivers to breed (Ref. 4967). Found in all types of habitat and occurs in groups of about 25 individuals; not exported for trade (Ref. 5595).

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=0.00955 (0.00430 - 0.02123), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Price category (Ref. 80766): Unknown.
