Max length : 25.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556); common length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 556)
Diagnosed from its congeners by the possession of the following characters: lateral line usually with 40-45 + 3 scales; 4-5 scale rows between lateral line and pelvic fin origin; 14 circumpeduncular scale rows; eye diameter equal to or greater than snout length; snout rounded, obtuse; and ventral profile of head without marked angle at articulation of lower jaw (Ref. 59043).
A short-lived species which lives in lakes and mountain streams, including the middle reaches of rivers (Ref. 11240). Also found in reservoirs in hilly areas. Juveniles occur in shallow areas with slow current and move to deeper and faster waters in late July. Opportunistic feeder, but preying mainly on aquatic invertebrates (Ref. 59043). Threatened due to pollution, habitat destruction and the introduction of other species (Ref. 26100).
生活在湖與山地溪流中的一種生命期短的種, 包括河的中游.(參考文獻 11240) 隨機的 (參考文獻 59043), 主要捕食無脊椎動物。 產卵在四月與五月。 受到威脅的由於污染，棲息地破壞與其他魚種的引入.(參考文獻 26100)
