Abstract:In this study, the specific activity of digestive enzymes of Sebastes schlegeli juvenile subjected to starvation and refeeding was determined at 17.6±0.2℃. The experiment included four treatments, and within each treatment there were three replicates. Treatment A was the control group, which were fed normally during the process of the study. Treatment B experienced 5d food deprivation and 50d refeeding, Treatment C experienced 10d food deprivation and 45d refeeding. Treatment D experienced 15d food deprivation and 40d refeeding. The experimental results showed that the activities of protease and trypsin decreased obviously during the starvation; the activity of lipase went on a downward trend, which was not significant; the activity of amylase increased greatly during the early days of starvation. After refeeding， except protease in intestines and trypsin in liver, activities of all other digestive enzymes returned to the normal level.
