摘要
关于鱼类视觉运动反应特性的研究，国外已有不少报导，但国内这方面工作还很少开展。研究鱼类视觉运动反应特性，对于阐明鱼类趋流和集群机制，探讨鱼类视觉特点和游泳能力具有重要的理论意义，并且在设计改进渔具渔法和控制鱼类行为等方面也有一定的实用价值。
The opotomotor reaction of three young freshwater cyprinids, in eluding silver carp (Hypophthalmichthys molitrix), carp (Cyprinus carpio), and grass carp (Ctenph-aryngodon idellus) has been dealt with in this paper. The results are as follows:(1) The reaction rate reduces as the weakening of illuminance and the increase of stimulus frequency.(2) Light colour has no obvious effect on the reaction rate of carp, but evident on silver carp and significant on grass carp.(3) The upper followable stimulus frequency rises as the increase of the strength of illumination. Light colour has certain effect on the former.(4) Both illuminance and light colour have no evident effects on the chron-following rate and angular displacement following rate. As to stumilus frequency it has little effect on chron-following rate but significant on the angular displacement follwoing rate.(5) There are three types of behaviour manifestation to the optomotor reacition of the three fishes.
