Lengte bij maturiteit / Grootte / Gewicht / Leeftijd

Maturity: L_m 23.8, range 23 - 25 cm
Max length : 48.0 cm TL mannelijk / geslacht onbekend; (Ref. 7248); max. gepubliceerd gewicht: 2.9 kg (Ref. 5693); max. gerapporteerde leeftijd: 7 Jaren (Ref. 7248)

Prefers deep main river channels and floodplain lagoons (Ref. 7248) with sandy bottoms (Ref. 7248, 52307). Feeds primarily on snails, bivalves and insect larvae (Ref. 7248, 52307), rarely also on fish or plants (Ref. 52307). Ovophilic (Ref. 52307), female mouthbrooder (Ref. 7248, 52307), breeds in early summer (Ref. 7248). Up to 700 eggs may be laid per female and per brood; males construct shallow, rounded pits approximately 20-30 cm in diameter, preferably in regions containing vegetation (Ref. 52307).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01950 (0.00893 - 0.04257), b=3.02 (2.83 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.5 ±0.52 se; based on food items.

Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tm=1-3; tmax=6.5; Fec=300).

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).

Prijsklasse (Ref. 80766): Unknown.
