| 采用自行设计的鱼类游泳能力测试槽，用“流速递增法”测定了鲤（Cyprinus carpio）（体长24.46±5.9cm）、鲫（Carassius auratus）（体长13.66±4.7cm）、鲢（Hypophthalmichthys molitrix）（体长32.73±3.7cm）、鳙（Aristichthys nobilis）（体长30.47±1.7cm）以及蒙古鲌（Culter mongolicus mongolicus）（体长23.51±3.1cm）等五种鱼类的感应流速。结果表明鲤、鲫、鲢、鳙以及蒙古鲌的感应流速分别是（3.55±2.43）、（2.408±2.00）、（4.605±2.575）、（2.033±1.019）和（0.135-3.930）cm?s-1，相对感应流速分别是（0.147±0.097）、（0.182±0.166）、（0.142±0.078）、（0.067±0.034）和（0.08±0.054）BL?s-1； 鱼类的体长与感应流速不存在相关关系；相对感应流速更加准确的表示鱼类的感应流速；不同鱼类之间的感应流速差异极显著（P<0.01），鱼类的感应流速是进化的结果。 |

| By using self-made test chamber and the method of increasing velocity，this paper studied the induction velocity of Cyprinus carpio (body length 24.46±5.9cm)，Carassius auratus (body length 13.66±4.7cm)，Hypophthalmichthys molitrix (body length 32.73±3.7cm)，Aristichthys nobilis (body length 30.47±1.7cm) and Culter mongolicus mongolicus (body length 23.51±3.1cm). The induction velocity of Cyprinus carpio, Carassius auratus, Hypophthalmichthys molitrix, Aristichthys nobilis and Culter mongolicus mongolicus was （0.0355±0.0244）,（0.0241±0.0200）, （0.0461±0.0257）, （0.0204±0.0102）and （0.0185±0.0120）m?s-1,and the relative induction velocity was （0.147±0.097）,（0.182±0.166）、（0.142±0.078）,（0.067±0.034）and（0.08±0.054）BL?s-1,respectively. No significant difference was observed between fish body length and induction velocity. The relative induction velocity is more precise to indicate induction velocity. But it was significant difference in induction velocity of different fish species (P<0.01). It was suggested that the induction velocity is the result of evolution . |
