Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; benthopelagic; potamodromous (Ref. 51243). Tropical
Asia: Mekong basin (Ref. 12693); also from Malaysia and Indonesia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 90.0 cm TL male/unsexed; (Ref. 37770); max. published weight: 16.0 kg (Ref. 37770)
Anal soft rays: 31 - 34. Dorsum dull grey; blunt snout lacking broad white band around muzzle; 24-35 gill rakers in the first arch (Ref. 12693).
Facultative air-breathing (Ref. 126274); Bears strong resemblance to P. bocourti but has different gill-raker counts and coloration. Diet consists mostly of benthic insect larvae and worms, with some free swimming insects, submerged plants and seeds (Ref. 12693). Undertakes upstream and downstream migrations in the Mekong mainstream (Ref. 37770). Length type for maximum size is assumed in TL.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00216 - 0.00967), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.8 ±0.27 se; based on food items.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (tm=3).
Fishing Vulnerability (Ref.
59153): High vulnerability (56 of 100).
