Abstract: The application of acoustic taming has a broad prospect in the exploitation of marine ranching as a technology of controlling fish behavior. In order to know the effects of acoustic taming with different wave frequencies on Sparus macrocephalus, the behavior of Sparus macrocephalus was studied by means of acoustic taming using 300 Hz and 400 Hz sine wave alternate sounds in combination with temperature control and baits. The results showed that Sparus macrocephalus experienced three different periods to the revulsive effect of the alternate sounds, which were adaptation period, variation period and stabilization period. The response time of Sparus macrocephalus was decreasing gradually, and closed to the value of control group. The response time of trial group was significant higher than that of control group in the first four days (P<0.01), and there was a positive feedback to sound stimulation from the fifth day. Moreover, the response time was lower than the values of control group on the tenth day, which was the minimum response time of the entire trial process. The aggregation ratios increased gradually at the trial process, and there was extremely significant difference (P<0.01) from the fifth day between the trial group and control group, and the aggregation ratios were maintained at 100% after the seventh day. Besides, It was found that when acoustic challenged, the tamed Sparus macrocephalus in the hungry state were more excited than the well-fed state. The results indicated that 300 Hz and 400 Hz sine wave alternate sounds had a distinct revulsive effect on response and aggregation of Sparus macrocephalus, and the alternate sounds could be used as a valid possibility in acoustic taming of Sparus macrocephalus, which also could play a greater effect in the control of fish behavior combining with baits.
