摘　　要：以贵州北盘江的花鱼骨(Hemibarbus maculates)和白甲鱼(Onychostoma sima)为研究对象,在矩形水槽中设置由气压为14.7 kPa,孔距为1.0 cm、2.5 cm、4.0 cm,孔径为1.0 mm、1.5 mm、2.0 mm所组成的9组气泡幕密度,采用单因子试验法研究不同密度的气泡幕分别对花鱼骨和白甲鱼的阻拦效果。结果表明,9种密度的气泡幕对花鱼骨和白甲鱼均有一定的阻拦效果,其中花鱼骨在密度Ⅲ(孔距1.0 cm、孔径2.0 mm)时阻拦效果最好,阻拦率为(96.00±2.65)%。白甲鱼在密度Ⅱ(孔距1.0 cm、孔径1.5 mm)时阻拦效果最好,阻拦率为(95.33±3.06)%。本研究可以为物理屏障拦鱼技术提供一定的理论和技术参考。The avoidance responses of Hemibarbus maculates and Onychostoma sima from Beipan River to bubble curtains with different density were investigated under laboratory conditions.The density of bubble curtains consisted of air pressure,air-hole spacing and air-hole diameter.The air pressure of each bubble curtains was 14.7 kPa,air-hole spacing was 1.0 cm,2.5 cm and 4.0 cm and air-hole diameter was 1.0 mm,1.5 mm and 2.0 mm respectively.The result showed all of the nine bubble curtains have a certain degree of intercepting on Hemibarbus maculates and Onychostoma sima,and the bubble curtain with 1.0 cm air-hole spacing and 2.0 mm air-hole diameter had the best intercepting effects on Hemibarbus maculates,results a average intercepting rate at 96.00% ± 2.65%.The bubble curtain with 1.0 cm air-hole spacing and 1.5 mm air-hole diameter had the best intercepting effects on Onychostoma sima,results a average intercepting rate at 95.33% ± 3.06%.This research provided theory and technology reference for blocking fish by physical barriers technology.
