Lengte bij maturiteit / Grootte / Gewicht / Leeftijd
Maturity: Lm 10.3, range 9 - 13 cm
Max length : 29.0 cm TL mannelijk / geslacht onbekend; (Ref. 128900); common length : 16.9 cm SL mannelijk / geslacht onbekend; (Ref. 35840); max. gepubliceerd gewicht: 232.30 g (Ref. 128900)
Dorsale stekels (totaal) : 3; Dorsale zachte stralen (totaal) : 7; Anale stekels: 3; Anale zachte stralen: 11 - 13. Completed lateral line, went downward suddenly at the pectoral fin, forming an angle, going upward along the anal fin, till the middle of the caudal fin. Green gray in the back, white in the stomach (Ref. 33303).
The species is common in large streams and reservoirs in Hong Kong but not favored as a table fish because the flesh is unpalatable and very bony; abundant in China where it is canned. The main bulk of the diet includes zooplankton, insects, crustaceans, algae and detritus.
