Length at first maturity / Size / Weight / Age

Max length : 120 cm SL male/unsexed; (Ref. 30857)

Short description Morphology | Morphometrics

Anal soft rays: 25 - 30. Dorsum dull grey with pale green iridescence; maxillary band of teeth forms a continuous row with no break in midline (Ref. 12693). Snout protruding with upper jaw tooth bands partly exposed when mouth is closed; large median vomerine tooth plate (Ref. 43281).

Biology     Glossary (e.g. epibenthic)

Occurs in large rivers (Ref. 12693) and enters flooded forests (Ref. 9497). Found in rapids and in deep slow reaches (Ref. 37771). Juveniles feed on prawns and insects; subadults and adults on prawns, insects and particularly mollusks which are more predominant in stomach contents than in any other Pangasius species (Ref. 7432) and on plants (Ref. 9497). Migrates into the middle Mekong along the Thai-Lao border as water levels and turbidity begin to increase. Reproduces early in the flood season and juveniles of 6 to 7 cm are taken by late June (Ref. 12693). Marketed fresh (Ref. 12693).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (0.00176 - 0.00623), b=3.15 (2.97 - 3.33), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.34 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K and tmax; Fec=18,000-42,000).
Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100) .
Price category (Ref. 80766):   Unknown.
