摘要
在300cm×100cm×75cm的循环水槽内,对体长40～60mm的幼鲻(Mugilcephalus)在6个不同光照强度、20min光照时间内、2个光照区域和2种光照模式下的趋光行为进行了统计分析。结果表明,6个光照强度对幼鲻的光反应没有显著的影响(P>0.05);20min内光照时间对幼鲻的光反应没有显著的影响(P>0.05);幼鲻对光呈均等反应,但对光较暗区的趋性更强一些(P<0.05);幼鲻在2种光照模式下的光反应总体趋势一致,但其光反应程度存在显著性差异(P<0.05)。结果表明幼鲻对光呈均等反应,但更趋暗光。
The wild black mullets of （40--60）mm length were observed and analysed to research their phototactic behavior in the 6 illumination levels and 20 minutes illumination time and 2 illumination modes and 2 illumination districts. The results were as follow, illumination intensity didn＇t influence the juvenile mullets＇ phototactic behavior significantly on the 6 levels （P〉0.05） ; the time length didn＇t influence the juvenile mullets＇ phototactic behavior significantly either （P〉 0.05） within 20 minates illumination time; the juvenile mullets had the average reactions to the illumination, but they prefer to the dimmer backgroud （P〈0.05） ; the general tendency of the juvenile mullets＇ phototactic behavior was uniform in the 2 illumination modes, but there were significant difference between two of them in the phototacic degree （P〈0.05）. It was indicated that the juvenile mullets make the average reactions to the different illumination intensities, but they prefer to the dimmer background.
