| 摘 要： | 测定和比较了千年笛鲷(Lutjanussebae)幼鱼不同消化器官的消化酶活性。结果表明,蛋白酶比活力为:肠>胃>肝胰脏(P<0·01);淀粉酶比活力为:肠>肝胰脏>胃(P<0·01);脂肪酶比活力为:肠>肝胰脏>胃,胃和肝胰脏间差异不显著(P>0·05),但二者和肠之间差异极显著(P<0·01)。千年笛鲷幼鱼肠道对食物的整体消化能力始终较强,肝胰脏和胃是消化食物的辅助器官。 |

| Abstract: | The activities of digestive enzymes in three alimentary organs of Lutjanus sebae were detected and compared. The results showed that the protease activity was intestine>stomach>hepatopancreas (P<0.01);and the amylase activity was intestine>hepatopancreas>stomach (P<0.01);and the lipase activity was intestine>hepatopancreas> stomach. The lipase activity difference between intestine and hepatopancreas or stomach was significant (P<0.01), but the difference between hepatopancreas and stomach was not significant (P>0.05). The digestive activities of intestine in young L.sebae were high. The stomach and hepatopancreas were auxiliary organs. |
