Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 1; Rayons mous dorsaux (Total): 4; Rayons mous anaux: 60 - 75. Differs from all other congeners by having a jet black pectoral-fin membranes. Branchiostegal rays 15-18 (Ref. 2091). Corner of mouth reaching only to anterior margin of eye (Ref. 7050).

Adults inhabit large streams and rivers (Ref. 12455). Fry occur at the mouth of small streams connected to larger rivers, where the bottom is muddy and with overhanging vegetation (Ref. 56749). Feeds on prawns (Ref. 56749). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205). Fishermen along Kapuas in Indonesia observed that it used to form large migratory schools in Kapuas mainstream but such schools had become less noticeable, and this was attributed to intensive gill netting. Usually consumed fresh or processed as salted fish (Ref. 56749). Reaches more than 150 cm TL (Ref. 7050).

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=0.00562 (0.00278 - 0.01137), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.5 ±0.80 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Assuming Fec > 10,000).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Catégorie de prix (Ref. 80766): Unknown.
