摘要
采用流水装置测定了中国明对虾(Fenneropenaeus chinensis)稚虾在4种光色处理下耗氧率的昼夜变化。实验设四种光色处理,分别为自然光(590nm)、黄光(580nm)、绿光(525 nm)和蓝光(435nm),光照周期为14L∶10D,水温为25.0±0.5℃,实验虾的规格为(5.507±0.147)g。主要实验结果如下:1、在自然光、黄光和绿光下,中国明对虾耗氧率的昼夜波动较大,对虾耗氧率的高峰出现在夜间,低谷出现在日间,且对虾在夜间的平均耗氧率显著高于日间(P<0.05);在蓝光下,中国明对虾耗氧率的昼夜波动较小,对虾耗氧率的高峰出现在日间,低谷出现在夜间,且对虾在夜间和日间的平均耗氧率差异不显著(P>0.05);2、在自然光、黄光和绿光下,中国明对虾的日平均耗氧率差异不显著(P>0.05),而对虾日平均耗氧率在蓝光和自然光下的差异显著(P<0.05)。
The effect of light colour on the diel rhythm of the oxygen consumption rate in juvenile Fenneropenaeus chinensis with average wet body weight of（5.507±0.147）g was examined under a flowing water apparatus at 25.0±0.5℃,and the four light colours were： natural light（590nm）,yellow light（580nm）,green light（525 nm）,and blue light（435nm）,respectively.The results were as follows： 1 under natural light,yellow light,and green light,the oxygen consumption rate of F.chinensis showed definite diel rhythm,the positive peak appeared at dark condition,while the negative peak appeared at illumination condition.Mean oxygen consumption rate of F.chinensis at dark condition was significantly higher than that at illumination one（P0.05）.Under blue light,the oxygen consumption diel rhythm of F.chinensis changed.The positive peak occurred at illumination condition,while the negative peak occurred at dark one.Mean oxygen consumption rates between the dark and illumination ones were not significant（P0.05）;2 there was no significant difference between the diurnal mean oxygen consumption rate of F.chinensis under natural light,yellow light,and green light（P0.05）,but the diurnal mean oxygen consumption rate of F.chinensis under natural light was significantly lower than that under blue light treatment.
