Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 9; Anale stekels 0; Anale zachte stralen: 12. Diagnosis: Hepsetus cuvieri can be distinguished from Hepsetus odoe based on a lower total number of gill rakers on the first gill arch, being 8–13 versus 14–21; a generally higher number of scales between the dorsal fin and the lateral line, 10.5–11.5 versus 7.5–10.5; a typically higher number of scales between the adipose fin and the lateral line, 6.5–7.5 versus 4.5–6.5; and a unique colour pattern characterized by a mottled appearance of the dark brown blotches on the lateral surface of the body versus the presence of vertical brown stripes/bars in that region in Hepsetus odoe (Ref. 93907).

Prefers quiet, deep water, like channels and lagoons of large floodplains; juveniles and fry inhabit well-vegetated marginal habitats (Ref. 7248). Adults feed on fish, juveniles feed on small invertebrates and fish (Ref. 7248). Multiple spawner; breeds over the summer months; relatively short-lived, only 4-5 years; also caught with drawnets (Ref. 7248).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00208 - 0.01208), b=3.13 (2.92 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).
