摘要
鱼类的游泳能力和游泳行为是成功设计过鱼设施的关键。为了探究长丝裂腹鱼（ Schizothorax dolichonema Herzenstein）的游泳能力，以野生长丝裂腹鱼（110.56 g ±35.88g）为对象，测定了它们的临界游泳速度，并记录了测定过程中的游泳行为。研究表明：（1）临界游泳速度为3.04～4.93BL/s；（2）运动耗氧率与游泳速度呈幂函数关系MO 2＝129.67＋15.63 U 2.34（ R 2＝0.983， P＜0.001），速度指数为2.34，表明能量利用效率相对较低；单位距离能耗（COT）与游泳速度的关系也呈幂函数关系COT＝0.14 U-1＋0.04U0.80（R2＝0.844， P＜0.001）；（3）随着游泳速度的增加，尾摆幅度的变化不显著，变化范围为0.18～0.32 BL，而尾摆频率和运动步长都呈线性增加的趋势。
The key point of the design of fish pass structure was to figure out the swimming performance and behavior of thetarget fish. To investigate the swimming performance of Schizothorax dolichonema Herzenstein, critical swimming speed andswimming behavior of wild S.dolichonema Herzenstein were studied in this experiment. Results showed that： （1） Criticalswimming speed was 3.04 ~4.93 BL/s.（2） Relationship between oxygen consumption and swimming speed was deter -mined to be MO2 =129.67 ＋15.63 U 2.34 （R2 =0.983, P 〈0.001 ）, with the speed index of 2.34, indicating relativelylow energy efficiency. COT =0.14U -1 ＋0.04 U 0.80 （R 2 =0.844 , P 〈0.001） described the relationship between cost oftransport and swimming speed.（3） The tail beat frequency and stride length increased a lot ,while the tail beat amplitude（0.18 -0.32 BL） did not change much with swimming speed increasing.
