静水与流水下气泡幕对异齿裂腹鱼的阻拦效应

BLOCKING EFFECT OF STATIC WATER AND FLOWING WATER BUBBLE CURTAIN ON SCHIZOTHORAX OCONNORI

  • 摘要: 为了探究不同水流条件下不同形式的气泡幕对异齿裂腹鱼(Schizothorax oconnori)趋避行为的影响。在黑暗环境下测试了两种流速条件(静水与流水)、三种气量(15、30、45 L/min)及两种摆放角度(与水流方向呈90°和45°)的气泡幕对异齿裂腹鱼的阻拦效果,在静水和流水条件下各设置一组空白对照(气量为0 L/min)。结果显示: (1)在静水条件下, 工况2阻拦率最高(50%); 在流水条件下, 工况7阻拦率最高(50%)。(2)气量15 L/min时, 流水及90°摆放阻拦时间显著大于其他工况; 30 L/min时, 静水及90°摆放阻拦时间远大于其他工况。(3)在静水和流水中, 当异齿裂腹鱼尝试次数达到6次左右时对气泡幕表现出适应性, 并在48min前通过气泡幕; (4)在流水中各工况下气泡幕的影响距离显著大于静水(P<0.05), 即异齿裂腹鱼产生逃逸行为时距离气管的距离显著大于静水中。研究可得出结论: 推荐阻拦效果最佳的组合方式为流水条件下15 L/min 90°摆放(工况7)、静水条件下30 L/min 90°摆放(工况2); 气泡幕连续阻拦时间不宜超过48min。实验结果可为实际工程中气泡幕的布置提供参考。

     

    Abstract: To explore the effects of different forms of bubble curtains on the avoidance behavior of the Schizothorax oconnori under different water flow conditions, two flow conditions (static water, flowing water), a blank control with a gas flow of 0 under both flow conditions, three gas flow (15, 30, 45 L/min) and two placement angles (90° and 45° to the water flow direction) were utilized under dark environment. The results showed that the working condition 2 had the highest hinder rate (50%) under static water conditions, and that the working condition 7 had the highest hinder rate (50%) under flowing water conditions. The hinder time under flowing water and 90° placement was significantly longer than other working conditions at 15 L/min of the air flow. The hinder time under static water and 90° placement was much longer than other working conditions at 30 L/min. In static water and flowing water, when the attempt number of Schizothorax oconnori reached about 6 times, it showed adaptability to the bubble curtain and passed through the bubble curtain within 48 minutes. The influence distance of the bubble curtain in the flowing water was significantly greater than that in the static water (P<0.05), and the distance from the bubble pipe was significantly greater than that in the static water when Schizothorax oconnori performed avoidance behavior. Therefore, the recommended condition for optimal hinder effect is to place 15 L/min 90 ° under flowing water conditions (Condition 7) and 30 L/min 90 ° under static conditions (Condition 2) with a continuous obstruction time of bubble curtains should not exceed 48 minutes. These results provide a reference for the practical engineering of the bubble curtain arrangement.
