Asia: Thailand to Indonesia. Reports of this species from the Mekong River basin are misidentifications of Wallgo micropogon (Ref. 51260).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 150 cm TL male/unsexed; (Ref. 7050); max. published weight: 86.0 kg (Ref. 2091)

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 4; Anal soft rays: 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).

Biology     Glossary (e.g. epibenthic)

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).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Assuming Fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Unknown.
