Short description Morfología | Morfometría

Radios blandos anales: 11 - 12. Can be diagnosed by having the following characters: dark transversal bars on dorsum present; dark spots absent on the center of each body scale in some specimens; usually two, sometimes three or four midlateral dark blotches on body; angle of the dorsal and ventralmost radii of body scales between 110° and 180°; and cranial fontanel partially closed (Ref. 91907).

Adults are found in schools of 10-50 specimens in deeper water. They feed on plants (Ref. 13371). Distinct pairs breed on densely grown weedy places (Ref. 205).

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=0.00955 (0.00563 - 0.01619), b=3.05 (2.90 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Nivel trófico (Ref. 69278): 2.0 ±0.00 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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