Description synthétique Morphologie | Morphométrie

Diagnosis: This species can be distinguished from all other Hepsetus species by the following unique combination of characters: number of lateral line scales high, 49–60; nostril-lower jaw distance high, 40.4–47.6% of head length; number of gill rakers on first arch low, 14–22; number of scales between dorsal fin and lateral line 7.5-9.5; and number of scales between adipose fin and lateral line 4.5-6.5 (Ref. 88135).

The capture, in the Senegal River, of an individual measuring 510 mm SL has been mentioned, but not confirmed; the collections of the Museum of natural History in Paris include a head that is said to belong to a specimen collected in the Cavally River measuring 700 mm TL and wighing 4.000 g (Ref. 2914, 81278).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

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

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
