200Hz方波连续音对真鲷幼鱼驯化反应的研究
Research on the behavior of juvenile Chrysophrys major acoustic tamed through rectangular continuant at 200 Hz in Northern South China Sea
摘要
Abstract
In order to achieve the attractive effect of acoustic on Chrysophrysmajor which is one of the important multiplication species of marine ranching in Northern South China Sea. The behavior of juvenile Chrysophrys major in Northern South China Sea which body length was 4.4-6.6 cm acoustic tamed continuously for 8 days by rectangular continuant at 200 Hz under laboratory conditions. At the same time, a control experiment (without acoustic tame) was set up. The results showed that fish in control group distributed randomly. The attractive areaof trial group (acoustic tame) became smaller from 1st to 8th day. The response times and aggregation times of juvenile Chrysophrys major were decreasing gradually and keeping in low values from 4th day. The response times of trial group were shorter than control group during the whole taming process. The aggregation times of trial group began to be shorter than the values of control group fram 3rd day. The residence times were increased rapidly from 3rd day and higher than the values of control group during the whole process. The aggregation ratios were increasing gradually; there weren' t extremely significant changes from 4th day. The aggregation ratios of trial group were higher than the values of control group. It illustrated that rectangular continuant at 200 Hz has a distinct attractive effect on juvenile Chrysophrys major in Northern South China Sea, and the conditional reflex was established after 4 days of acoustic tame.关键词
