摘要
为研究气泡幕在驱赶、聚集和阻拦大泷六线鱼Hexagrammos otakii中的作用,在室内水槽中进行了压缩空气压力为0.04 MPa,孔径为1.0、2.0 mm,孔距为2.5、5.0 cm交互组合的4种不同密集程度的固定气泡幕对大泷六线鱼的阻拦效果试验。结果表明,4种气泡幕对大泷六线鱼均具有较为明显的阻拦作用,其中孔径为1.0 mm与孔距为2.5 cm组合的气泡幕阻拦效果最好,平均阻拦率为53.2%,试验鱼第一次穿越气泡幕所需要的平均时间为202.25 s。研究表明,气泡幕对大泷六线鱼的阻拦效果较为明显。
The effect of bubble curtains on blocking of fat greenling Hexagrammos otakii was studied under conditions of compressed air pressure of 0. 04 MPa in the indoor flume,bore diameter of 1.0 mm and 2. 0 mm,hole pitch of 2.5 cm and 5. 0 cm,and mutual combination of four crowding level fixed bubble curtains to provide basic data for fishes domestication in Marine Pasture. The results showed that the four bubble curtains had more obvious blocking effect for fat greenling,the best blocking effect under the bubble curtains with the bore diameter of 1.0 mm and the hole pitch of 2. 5 cm,with average block rate of 53. 2%, and average time needed for the first time through of 202. 25 s. The findings indicate that fat greenling is significantly blocked by the bubble curtains.
