摘　　要：长臀(Cranoglanis bouderius)和白甲鱼(Onychostoma sima)是目前北盘江主要放流鱼类,但这2种鱼的放流效果差异较大。由于鱼类的突进游速在一定程度上影响增殖放流的效果,故试验采用自制测试装置,用递增流速法测试了2种鱼的突进游速。结果显示,白甲鱼的突进游速大于长臀,且2种鱼的突进游速均随体长增加而近似线性增大;而相对突进游速则随着体长的增加而近似线性减小。研究结果可为北盘江鱼类增殖放流和放流效果评估,以及日后北盘江的拦鱼、诱鱼、集鱼船等鱼类资源保护措施的实施提供参考。Cranoglanis bouderius and Onychostoma sima,the main releasing fish in Beipan River,have obvious differences in their releasing effect. We tested the two fish′s burst swimming speeds by increasing velocity method with the device made by ourself. The results show that the burst swimming speed of O. sima was higher than that of C. bouderius. The burst swimming speed and relative burst swimming speed of the two fish increased and declined along with the increasing body length with linear approximation,respectively. The investigation provides references for assessment of enhancement and releasing effect for fish from Beipan River as well as protective measures for blocking fish,luring fish and fishing boat in Beipan River in the future.
