摘要
在16L∶8D和自然光照(Amb)两种光周期条件下养殖黄金鲈鱼,观察其体重增长及饲料转化情况。养殖试验结果发现经过5个月的饲养,黄金鲈鱼在16L∶8D的光周期下鱼体总重量的净增量是自然光周期下的2.90倍,饵料系数比自然光照条件下低54.8%。结果表明适当延长光照时间可以促进黄金鲈鱼的生长,降低饵料系数。
Yellow perch Perca flavescens was reared under 16L:8D light cycle and Amb photoperiod, respectively, and its growth and feed conversion were observed. The results showed that the biomass of yellow perch which was reared under the 16L:8D photoperiod is 2.90 times compared to that under Amb photoperiod, and the feed parameter was lower, and decreased to 54.8% of the latter. Longer photoperiod appropriately could stimulate the growth of yellow perch, and reduced its feed parameter.
