| 摘 要： | 为探索了解奥利亚罗非鱼在光场中的趋避行为规律。采用水平光梯度法，研究了4组不同生长阶段的奥利亚罗非鱼：Ⅰ组：20.0~50.0 mm；Ⅱ组：50.0~80.0 mm；Ⅲ组：80.0~110.0 mm；Ⅳ组：110.0~140.0 mm，在250、500、1000、1500、2000 lx白光光强梯度下的行为反应。同时对Ⅰ组奥利亚罗非鱼在不同波长单色光下（红、黄、绿、蓝）下的行为分布开展研究。结果表明：在白光下，4组奥利亚罗非鱼均表现出正趋光性，在250~2000 lx间趋光率随光照强度的增强呈现出先上升后下降的趋势，在1000 lx时趋光率达到峰值，其中近光区趋光率分别为67.5%、55.0%、55.0%、42.0%，总趋光率分别为96.0%、94.0%、96.5%、95.0%；奥利亚罗非鱼的白光适宜照度范围为：500~1500 lx；随着奥利亚罗非鱼的生长发育，近光区趋光率峰值Ⅰ>Ⅱ>Ⅲ>Ⅳ。此外，Ⅰ组奥利亚罗非鱼在不同单色光同一照度下的趋光率差异显著(P<0.05)，在蓝光、绿光下的趋光率高于红光、黄光，对不同单色光的趋集行为具有选择性。研究表明：奥利亚罗非鱼在不同光色、不同光强、不同生长阶段都具有选择性，研究结果在开发高效诱捕灯、提高工厂化养殖效益等方面具有积极意义。

| Abstract: | The photo gradient method was used to study the dynamic phototaxis behaviors of Blue tilapia（Oreochromis aureus） during four groups divided by different growth stages：Ⅰ：20.0-50.0 mm,Ⅱ：50.080.0 mm,Ⅲ：80.0-110.0 mm,Ⅳ：110.0-140.0 mm,which was exposed to the white lights at five intensities 250,500,1000,1500,2000 lx,in order to understand the regular behavior of Blue tilapia in optical field.Furthermore,the behavioral response of Ⅰgroup under four different wavelength lights（Red,Yellow,Green,Blue） was discussed.The results showed that under the white light four groups of Blue tilapia behave positive phototaxis.The phototaxis index of four groups increased with the boosted light intensity which the range was 250-1000 lx,then decreased with the boosted light intensity when 1000-2000 lx.The phototaxis index reached the maximum when the light intensity was 1000 lx,which were 67.5%,55.0%,55.0% and 42.0% respectively in high light district.The total phototaxis indexes of four groups were 96.0%,94.0%,96.5% and 95.0% respectively.Blue tilapia preferred light intensity between 500-1500 lx.The phototaxis index decreased with the development of Blue tilapia,and the maximum phototaxis index rank was ⅠⅡⅢⅣ.Otherwise,Blue tilapia of Ⅰgroup performed differently in four color lights.It preferred blue and green lights to Red and Yellow lights.It was concluded that Blue tilapia behaved selectively in different light intensity,different wavelength lights and at different growth stages.The results could be used for developing trapping light equipments and improving benefits of industrial culture. |
