生態学
; 新鮮な水; 汽水性の 底生の漂泳性; pH range: 7.0 - ? ; dH range: 15 - ?; 深さの範囲 0 - 10 m (Ref. 6898). Tropical; 18°C - 22°C (Ref. 2059)
Asia: China, North and South Korea, Hong Kong, Japan and Amur River basin (Ref. 1441) to Red River drainages; Mongolia (Ref. 57778). Several countries report adverse ecological impact after introduction. Introduced in Iran (Ref. 39702).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 10.3, range 9 - 13 cm
Max length : 29.0 cm TL オス/雌雄の選別がない; (Ref. 128900); common length : 16.9 cm SL オス/雌雄の選別がない; (Ref. 35840); 最大公表体重: 232.30 g (Ref. 128900)
背面の脊椎 (合計) : 3; 背鰭 (合計) : 7; 肛門の骨: 3; 臀鰭: 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.
