Description synthétique Morphologie | Morphométrie

Well-developed adipose eye-lid, covering most of eye except pupil in large adults, less extensive in juveniles; presence of a large symphyseal knob in lower jaw fitting in a median notch in upper jaw (Ref. 43281).

Biologie     Glossaire (ex. epibenthic)

Inhabits mainstreams of middle reaches in deep rocky rapids. Juveniles occur in tributaries (Ref. 58784). A large fast-swimming predator, feeding on fish of the middle and the upper water levels. Although most common along the Thai-Lao border at the mouth of the Mun River, its numbers have drastically decreased in recent years. This is perhaps due to dam construction or excessive gill netting, to which active pursuit predators, like this species, are particularly vulnerable (Ref. 12693). Undertakes upstream migration at the same time as Probarbus sp. in December-February (Ref. 37770) which may be related to spawning activity (Ref. 9497). Attains over 30 kg (Ref. 9497).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00451 - 0.02020), b=3.02 (2.84 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  4.5   ±0.80 se; Based on food items.
Résilience (Ref. 69278):  Très faible, temps minimum de doublement de population supérieur à 14 ans (Preliminary K or Fecundity.).
Vulnérabilité (Ref. 59153):  Very high vulnerability (80 of 100) .
