Teleostei (teleosts) > Siluriformes (Catfishes) > Pangasiidae (Shark catfishes)
Etymology: Pangasius:The Vietnamese name of a fish (Ref. 45335). More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range Ecology
Analsoft rays: 31 - 34. Dorsum dull grey; blunt snout lacking broad white band around muzzle; 24-35 gill rakers in the first arch (Ref. 12693). Body shape (shape guide): elongated.
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.

IUCN Red List Status (Ref. 130435: Version 2025-1)
Phylogenetic diversity index (Ref. 82804): PD50 = 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). 🛈
