Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7-8; Anal soft rays: 12 - 14; Vertebrae: 52 - 53. Bright red caudal fin in specimens bigger than about 15 cm SL; whitish in smaller ones (Ref. 27732). Adipose fin long (length of adipose-fin base 18.7-25.7% SL), with a gently-sloping anterior margin; dorsal spine poorly ossified and short (7.5-11.4% SL) without serrations on posterior edge; length of dorsal-fin base 16.3-18.3% SL; maxillary barbels reaching to at least middle of adipose fin base (230.1-297.0% HL) (Ref. 38441). Head flat rather than conical; a short occipital process not close to basal bone of dorsal fin; no stripes on body (Ref. 12693).

Asia: Mekong basin (Ref. 27732). Reported from Chao Phraya, Maeklong and Peninsular Thailand river systems (Ref. 26336).

Biology     Glossary (e.g. epibenthic)

Occurs in large upland rivers. Common in areas with rocky bottoms and irregular depths (Ref. 12693). Apparently does not migrate but reproduces locally and enters the flooded forest during high water in July-October (Ref. 38441). Feeds on insects, prawns, fish (Ref. 33813) and crabs (Ref. 38441). Marketed fresh (Ref. 12693). Maximum weight reported for an individual caught in Mae Klong River, Thailand, reached 86 kg (J-F. Helias, pers.comm., 07/2002; see photo Hewyc_u0.jpg).

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=0.00575 (0.00243 - 0.01363), b=3.10 (2.89 - 3.31), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.60 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High vulnerability (64 of 100) .
Price category (Ref. 80766):   Unknown.
