Rückenflossenstacheln (insgesamt) : 2; Rückenflossenweichstrahlen (insgesamt) : 7; Afterflossenweichstrahlen: 37 - 40.

Occurs in medium to large-sized rivers (Ref. 12975). The stomachs of the specimens examined were more or less filled with mollusks, usually bivalves (Ref. 7432). Enters flooded forest (Ref. 9497). Migrates upstream when water levels begin to rise at the beginning of the flood season and moves downstream as water clears at the end of the flood season. Marketed fresh (Ref. 12693).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00316 (0.00181 - 0.00553), b=3.12 (2.96 - 3.28), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.44 se; based on food items.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).

Preiskategorie (Ref. 80766): Unknown.

Nutrients (Ref. 124155): Calcium = 83.9 [38.5, 178.7] mg/100g; Iron = 1.11 [0.53, 2.01] mg/100g; Protein = 16.3 [14.7, 17.9] %; Omega3 = 0.282 [0.118, 0.666] g/100g; Selenium = 100 [46, 242] μg/100g; VitaminA = 22.3 [7.0, 60.9] μg/100g; Zinc = 1.36 [0.92, 2.02] mg/100g (wet weight);
