中文摘要: |
在水温18~22℃的流水循环条件下,研究了饥饿胁迫对鲤(Cyprinus carpio)内脏蛋白酶和淀粉酶活性的影响。实验设计为4组,每组3个重复,鲤分别饥饿0、10、20、30d。试验结果表明,随着饥饿时间的延长,体重、含肉率变化呈现下降趋势并趋向稳定;饥饿对鲤肠道和肝胰脏蛋白酶有显著影响(P<0.05),随着饥饿时间的延长,前、中、后肠及肝胰脏内蛋白酶活性呈现先升高后下降的趋势;前肠淀粉酶活性变化显著(P<0.05),呈现下降趋势,其余淀粉酶变化均不显著。 |
英文摘要: |
The aim of the present study was to determine the effect of starvation on digestive enzymes activity of the carp (Cyprinus carpio) at the water temperature 18 -20℃ in the cycle and flow water aquarium. The experiment was designed for four groups with three replication,which were 0 day(control) , 10 days, 20 days, 30days group. The results showed That there was a trend to drop first and keep stabilization for Cyprinus carpio body weight and Meat Content with the prolongatin of starvation, and that Effect of starvation stress on the the activity of protease in intestine and hepatopancreas of Cyprinus carpio was significant, with the prolongatin of starvation, there was a trend to increase then drop for the activity of protease in fore-gut, mid-gut hind-gut and hepatopancreas of Cyprinus carpio. And that the variatin for activityof amylase in fore-gut was significant butthat of the others was no significant. |
