摘要

摘要: 研究了饥饿和再投喂对千年笛鲷(Lutjanus sebae)幼鱼消化酶活性的影响.实验设计分成6组,分别饥饿处理0(对照),2,4,6,9和11 d,然后在饱食的条件下恢复投喂10 d.分别测定饥饿和恢复投喂过程中千年笛鲷幼鱼蛋白酶、淀粉酶、脂肪酶3种消化酶的活性.结果表明,在饥饿过程中,蛋白酶和脂肪酶活性下降明显,淀粉酶起伏较大;恢复投喂后,蛋白酶和脂肪酶活力与饥饿前相比都有所上升,但蛋白酶活力总体上仍低于同步取样对照组,脂肪酶活力总体上高于对照组水平,淀粉酶活力恢复到对照组水平,并且基本上没有变化.

Abstract: The specific activities of digestive enzy mes of Lutjanus sebae juveniles were determined during starvation and refeeding.The fish were starved for 0(control), 2, 4, 6, 9, 11d and refed for 10 d with enough food.The specific activities of protease, lipase and amy lase were determined during starvation and refeeding.The results showed that the specific activities of protease and lipase decreased clearly during the starvation, but the specific activity of amylase had a bigger wave;after refeeding, the specific activities of protease and lipase had a little rising, but the protease specific activity was lower than the control group while lipase was higher.The specific activity of amylase had no change compared with the control group.
