Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 16 - 23; Raggi dorsali molli (totale) : 44 - 45. Caudal fin rays 15 and caudal fin distinctly separated from dorsal and anal fins (Ref. 97143).

Occurs in running and stagnant waters (Ref. 4833). Found in fresh and brackish waters and deltas of large rivers, common in ponds and slow flowing rivers with vegetation in plains (Ref. 41236). Inhabits still waters with silt or mud substrate. Believed to be common in rice paddy fields. Nocturnal feeder, on insects and worms.

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=0.00324 (0.00187 - 0.00559), b=2.99 (2.84 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.33 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Fec = 250).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).

Price category (Ref. 80766): Unknown.
