采用150 Hz矩形波断续音,对体质量为32.3~65.7 g的褐菖鲉Sebastisous marmoratus幼鱼进行了音响驯化试验。结果表明:驯化3d后,试验组褐菖鲉对声音开始产生趋向性;试验组鱼的反应时间在驯化第2~5天时,虽然明显高于对照组(P<0.05),但总体呈下降趋势,驯化第9天时与对照组接近(P>0.05),驯化第10天~第25天时总体维持在一个较低水平,与对照组无显著性差异(P>0.05),驯化第17天时反应时间达到最低值2 s;试验组鱼的聚集时间在驯化第2天~第6天时下降明显,之后随着驯化时间的延长,聚集时间下降趋势趋缓,驯化第12天时接近对照组( P>0.05),并从第14天开始低于对照组,驯化第14天~第16天、第18天~第21天、第23天~第25天时均显著低于对照组(P<0.05),驯化第19天时聚集时间降到最低值26 s;试验组鱼的聚集率总体呈上升趋势,驯化第20天时聚集率达到最高值86.7%,而对照组则时高时低,并且从第3天开始显著低于试验组( P<0.05);在试验的后5 d投放人工鱼碓后,放音时仍然能将试验组(不投放饵料)大部分褐菖鲉从鱼礁中引出,聚集率最低为75.0%,与对照组有极显著性差异(P<0.01)。研究表明,150 Hz矩形波断续音能够对褐菖鲉有很好的诱集作用,而且能明显吸引聚集在人工鱼礁中的褐菖鲉。
採用150 Hz矩形波斷續音,對體質量為32.3~65.7 g的褐菖鲉Sebastisous marmoratus幼魚進行瞭音響馴化試驗。結果錶明:馴化3d後,試驗組褐菖鲉對聲音開始產生趨嚮性;試驗組魚的反應時間在馴化第2~5天時,雖然明顯高于對照組(P<0.05),但總體呈下降趨勢,馴化第9天時與對照組接近(P>0.05),馴化第10天~第25天時總體維持在一箇較低水平,與對照組無顯著性差異(P>0.05),馴化第17天時反應時間達到最低值2 s;試驗組魚的聚集時間在馴化第2天~第6天時下降明顯,之後隨著馴化時間的延長,聚集時間下降趨勢趨緩,馴化第12天時接近對照組( P>0.05),併從第14天開始低于對照組,馴化第14天~第16天、第18天~第21天、第23天~第25天時均顯著低于對照組(P<0.05),馴化第19天時聚集時間降到最低值26 s;試驗組魚的聚集率總體呈上升趨勢,馴化第20天時聚集率達到最高值86.7%,而對照組則時高時低,併且從第3天開始顯著低于試驗組( P<0.05);在試驗的後5 d投放人工魚碓後,放音時仍然能將試驗組(不投放餌料)大部分褐菖鲉從魚礁中引齣,聚集率最低為75.0%,與對照組有極顯著性差異(P<0.01)。研究錶明,150 Hz矩形波斷續音能夠對褐菖鲉有很好的誘集作用,而且能明顯吸引聚集在人工魚礁中的褐菖鲉。

In this paper, juvenile dusty stingfish Sebastisous marmoratus with body weight of 32. 3-65. 7 g was tamed for behavior by 150 Hz square rectangular interval sound. It was found that the juveniles in the treatment group became phonotaxis to the sound 3 days after being tamed. The response time of the fish in the treatment group to the sound was shown to be descended rapidly from the second day to the fifth day, even though significantly dif-ferent from that in the control group (P<0. 05), nearly to the control group at the 9th day, and at a low level from the 10th day to the 25th day, without significant difference (P>0. 05), the minimal level (2 seconds) at 17th day. The aggregation time of the fish in the treatment group was found to be descend from the 2nd day to the 6th day, near to that in the control group at the 12th day (P>0. 05), lower than that in the control group from the 14th day, significant difference between the two groups at the 14 th-16th day, 18-21st day, and 23-25th day, and the minimal level of 26 seconds at 19th day. The fish had gradually increase in aggregation rate in the treatment group, the maximal level of 86. 7% at the 20th day, and the fish in the control showed irregular aggregation, significantly lower than the fish in the treatment group in the third day (P<0. 05). From the 26th day, the dusty stingfish ju-veniles were not fed in the tanks where cylindrical artificial reefs were disposed and find the sound aggregation. In the last 5 days, the fish still showed phonotaxis to the sound, the minimal aggregation rate of 75. 0% and very sig-nificantly different from the control group ( P<0 . 01 ) . The findings indicated that 150 Hz rectangular interval sound had good effect on aggregation of the dusty stingfish juveniles, even in the cylindrical artificial reefs.
