摘　　要：塔里木河流域叶尔羌高原鳅是偏肉食的杂食性鱼类。喜夜间活动觅食,生存的最低临界温度为5℃,最高临界温度为33℃,适宜水温在19℃。有弱趋光性。溶氧低于2 mg/L时活动不正常,水体温度在20℃时,叶尔羌高原鳅的时窒息点为1.18 mg/L。The Triplophysa(Hedinichthys) yarkandensis dinichthy's habits,including it's thermophilic habits,it's feeding habits and it's phototaxiaing habits were observed in the experiment.The results shows that the lowest critical temperature of Triplophysa(Hedinichthys)yarkandensis was 5 ℃,the highest critical temperature was 33 ℃ and was hermophilic at 19 ℃.Triplophysa(Hedinichthys)yarkandensis would stifled when dissolved oxygen below 1.18 mg/L when the activities wore not normal at 20℃ of water temperature.
