Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 9.0 range ? - ? cm
Max length : 40.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 59043)
Diagnosed from its congeners by having the following characters: lower jaw edge straight; 61-75 + 3-4 scales on lateral line; anal fin usually with 9½ branched rays; 22-31 gill rakers; usually 6-5 pharyngeal teeth; and caudal peduncle depth 1.8-2.2 times in its length (Ref. 59043).
Inhabits middle stretches of rivers in areas with current. Can survive in reservoirs. Occurs in groups, especially during pre-reproduction migration (Ref. 59043). Also found in lakes (Ref. 26100). Feeds on vegetal matter, small invertebrates and detritus (Ref. 59043). Spawning occurs in spring in shallow water, on gravel and sometimes on timber pilings in the river. Threatened due to the introduction of other species (Ref. 26100).
一個長命的種發現於河而且偶見於湖了。 它的食性由有硬外殼的藻類，矽藻與無脊椎動物組成。 在春天在淺水區中產卵, 在礫石上與有時在河中的木材樁材上。 受到威脅的由於其他魚種的引入.(參考文獻 26100)
