Etymology: Pangasius: The Vietnamese name of a fish (Ref. 45335); silasi: Named for Dr. E.G. Silas, who has made important contributions to taxonomy of Indian fish species, their biogeography and evolutionary divergence with the eminent scientist Prof. S. L. Hora.

Short description Bestämningsnycklar | Morfologi | Morfometri

P. silasi differs from its congener P. pangasius by having vomero-palatal teeth confluent as an uninterrupted curved band (vs. two lunate vomeropalatal teeth patches on each side with a wide gap in the center) and 48 vertebrae (vs. 44). It is also distinguished from P. myanmar, which is reported from Myanmar and has overlapping distribution with P. pangasius. It is also diagnosed from all congeners by its vomero-palatine dentition (Ref. 117930).

Facultative air-breathing (Ref. 126274)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01047 (0.00428 - 0.02559), b=3.01 (2.80 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
