Length at first maturity / Taille / Poids / Âge

Maturity: L_m 11.3, range 10 - 12.5 cm
Max length : 34.5 cm SL mâle / non sexé; (Ref. 13337); poids max. publié: 1.0 kg (Ref. 7248); âge max. reporté: 6 années (Ref. 7248)

Favors deep permanent floodplain channel and lagoons, with sandy bottom and vegetation (Ref. 7248, 52307). Feeds on aquatic insects, crustaceans and snails (Ref. 7248). Ovophilic, agamous (Ref. 52307) female mouthbrooder (Ref. 7248, 52307). Males construct a nest where the eggs are initially laid; mature at 10-12 cm length; useful snail control agent (Ref. 7248).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01862 (0.00880 - 0.03939), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.6 ±0.54 se; based on food items.

Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (tm=2; tmax=5.5).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Catégorie de prix (Ref. 80766): Unknown.
