Etymology: Osteochilus: Greek, osteon = bone + Greek, cheilos = lip (Ref. 45335). More on author: Fowler.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; potamodromous (Ref. 51243); depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C -

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 15.0 cm SL male/unsexed; (Ref. 30857)
Usually 12-13 branched dorsal rays; in life, body plain greenish with pink fins, and a dark, vertically elongated blotch above pectoral fin (Ref. 27732).
Found at midwater to bottom depths in large and medium-sized streams. Moves into flooded forests or open fields and begins to re-enter rivers in October. Young of the year are first seen in August. Feeds on periphyton, phytoplankton and some detritus. Usually used to make prahoc (Ref. 12693).

Bayesian length-weight: a=0.01122 (0.00461 - 0.02730), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
