Description synthétique Clés d'identification | Morphologie | Morphométrie

Differs from Ballerus sapa by having superior mouth, 62-77 scales on lateral line, and small eye with diameter about 2/3 of snout length in individuals larger than 10 cm SL (Ref. 59043).

Occur in large lowland rivers with backwaters and also in eutrophic lowland lakes. Feed mainly on zooplankton in open water of backwaters and other still water bodies. Spawn along shores of rivers or in backwaters on submerged vegetation and also on gravel in moderate current. Migrate upriver in long distances to suitable spawning sites. Juveniles stay in backwaters and flooded zones along rivers. Enter freshened parts of seas to forage. Life span reaches more than 10 years. Locally threatened by habitat alterations along river banks (Ref. 59043).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves

Mostly spawn several times during their life. Spawning lasts usually for 1-2 weeks. Female spawn once a year. Male often guard spawning territories along the shoreline (Ref. 59043).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00594 - 0.00735), b=3.13 (3.10 - 3.16), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Niveau trophique (Ref. 69278): 3.2 ±0.36 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (K=0.18-0.19; tm=4-5).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
