The compensatory growth in the Chinese shrimp(Penaeus chinensis)following starvation
中国对虾继饥饿后的补偿生长研

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 significantly lower than that of group C. At the end of experiment the mean body weight of group S4 was similar to that of group C, while the body weight of group S8 and group S12 was still significantly lower than that of group C. Upon realimentation after periods of starvation, the feeding rate in terms of wet weight in each previously starved group were significantly higher than those in group C. The results indicated that there was completely or partially compensatory effect in the recovery growth in the Chinese shrimp following starvation, and that the compensatory effect mainly resulted from significant increase of the feeding level in the recovery growth.
