摘  要：
为了研究气泡幕对异齿裂腹鱼的阻拦效果,在环形水槽装置中分别设置60、90、120 L·min-1 3种不同气量的气泡幕,在静水条件下,比较不同时间段气泡幕对异齿裂腹鱼的阻拦效果和异齿裂腹鱼空间分布的变化.结果表明:3种气量的气泡幕对异齿裂腹鱼都有明显的阻拦效果,且阻拦率无显著差异(P=0.130),在气量为60 L·min-1时阻拦率最高,为81.3%;实验过程中鱼对气泡幕无明显的适应性; 90和120 L·min-1两种气量下,异齿裂腹鱼喜欢在气泡幕附近停留.本研究结果可为气泡幕诱驱鱼技术在工程上的应用提供参考.

摘  要：
To investigate the blocking effect of bubble curtain on Schizothorax oconnori,three kinds of bubble curtain with different gas flows( 60,90 and 120 L·min~(-1)) were set up in the ring-shaped water tank. Under the conditions of still water,the blocking effect of bubble curtain on S. oconnori in different periods and the spatial distribution of the fish were observed. Three kinds of bubble curtains had obvious blocking effect on the fish,but with no significant difference in blocking rate( P = 0.130). The highest blocking rate reached 81.3% when the gas flow was at60 L·min~(-1). The fish had no obvious adaptability to the bubble curtain during the experiment. In addition,the fish preferred to stay near the bubble curtain at gas flows of 90 and 120 L·min~(-1).Our results provide reference for the application of bubble trap technology in engineering.
