摘要
在19～24℃条件下对鲻鱼(初始体重:204.42g±23.13g)进行了不同时间的饥饿处理后再充分投喂的恢复生长实验。实验设定2种投喂方式,对照组(饱食组)在实验期间一直投喂,饥饿组在限食期则不投喂食物,重喂期则恢复投喂。实验期为8个星期。取样分别在限食期的第0、1、2、4周和重喂期的1、2、4周,每次6条鱼。结果表明:饥饿状态下,鲻鱼血糖,血脂和血浆蛋白含量都显著降低;再充分投喂后,各血液生化指标均恢复到对照组水平,实验结果表明鲻鱼饥饿4个星期后,在4个星期的恢复生长过程中产生了显著的补偿效应。
Compensatory growth of mullet （Mugil cephalus Linnaeus）, following a period of feed deprivation, were studied at Nan＇ao Marine Biology Station, Shantou, China, between December, 2001 and March, 2002.In the study, the control group was fed to satiation during the 8-week experimental period. The other group were deprived from feed for 4 weeks and then were fed to satiation for 4 weeks. The blood were sampled from six fish each time at weeks 0, 1, 2, 4 in the period of feed deprivation and at weeks 1, 2, 4 in the period of re-feeding, respectively.The results showed that during feed deprivation, the concentrations of blood glucose, plasma lipid and plasma protein all have a significant fall. After refeeding, all blood biochemical indices were recovered to the levels of fed controls. The results suggest that mullet has a completely compensatory growth during refeeding.
