摘　　要：在水温为17.6±0.2℃条件下,研究了饥饿和恢复投喂对许氏平鲉幼鱼肝脏和肠主要消化酶活性的影响。实验分4组,每组设3个平行,其中A组为对照组,即在实验过程中正常投喂;B组饥饿5d恢复投喂50d;C组饥饿10d,恢复投喂45d;D组饥饿15d,恢复投喂40d。实验结果表明,蛋白酶、胰蛋白酶随饥饿时间的延长其活性下降明显,脂肪酶活性虽有下降趋势但不明显,而淀粉酶则在饥饿初期活性大幅度上升;恢复投喂后除了肠蛋白酶和肝胰蛋白酶外,其他消化酶活性均达到对照组水平。In this study, the specific activity of digestive enzymes of Sebastes schlegeli ju- venile subjected to starvation and refeeding was determined at17.6±0.2℃. The experiment in- cluded 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 depriva- tion and 45d refeeding. Treatment D experienced 15d food deprivation and 40d refeeding. Theexperimental results showed that ing the starvation; the activity of the activity of amylase increased except protease in intestines and turned to the normal level. the activities of p lipase went on a greatly during th trypsin in liver, sed obviously dur- as not significant; After refeeding, rotease and trypsin decrea downward trend, which w e early d activities ays of starvation. of all other digestive enzymes re
