摘 要 ：:1 999年 7至 8月份 ,在 2 5.0± 0 .5℃条件下对中国对虾 (湿重 ,1 .4 54± 0 .1 50 g)进行了不同时间的饥饿处理后再供食的恢复生长实验。对照组 C连续饱食投喂 32 d;处理组 S4、S8和 S1 2分别饥饿 4、8和 1 2 d后再饱食投喂 2 8、2 4和 2 0 d。主要结果如下 :饥饿结束时各处理组的干重和湿重显著低于对照组 ( P<0 .0 5) ;实验结束时 S4组和对照组间的干重和湿重差异不显著 ( P>0 .0 5) ,而 S8和 S1 2两组的干重和湿重仍显著低于对照组 ( P<0 .0 5) ;恢复生长后各处理组的湿重摄食率显著高于对照组 ( P<0 .0 5)。实验结果表明 ,中国对虾继饥饿后再恢复喂食出现完全或部分补偿生长效应 ,且这种补偿生长效应主要是通过恢复生长阶段食欲增大 ,摄食水平提高实现的。

Abstract:The recovery growth experiment in the Chinese shrimp with initial wet weight of 1.454g, following different periods of starvation, was conducted from July to August,1999. The experiment lasted for 32 days for each test group. Group C, S4, S8 and S12 were deprived food for 0 (control), 4, 8 and 12 days, respectively. Then each group was refed at ad libitum ration level for its rest experimental time. At the end of starvation mean,the body weight of each starved group (S4, S8 and S12) was significant...
