Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 1; Dorsale zachte stralen (totaal) : 7 - 8; Anale zachte stralen: 12 - 14; Wervels: 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).

Biologie     Verklarende woordenlijst (bv. 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 based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00607 - 0.01980), b=3.00 (2.84 - 3.16), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.7   ±0.60 se; based on food items.
Weerstandsvermogen (Ref. 120179):  Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (78 of 100).
