Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 16 - 23; Mjukstrålar i ryggfenan (totalt) : 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.

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).

Trofisk nivå (Ref. 69278): 3.1 ±0.33 se; based on food items.

Resiliens (Ref. 120179): Mellan, lägsta populationsfördubblingstid 1,4-4,4 år (Fec = 250).

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