【摘要】 <正> 我国对虾资源较丰富,但由于长期过度捕捞和其它环境因素的影响,导致资源衰退。为了满足国內外市场的需要,目前我国正在大力发展对虾的人工养殖事业。人工饵料是现代化养殖事业中重要的一环,解决好这个问题,就能大大促进人工养殖。对虾消化酶的研究可以为人工饵料的合理配方提供依据;因为对虾在不同生长发育阶段,对其食物有不同的需求,而消化酶的变化,在一定程度上可以反映它的这种生理状况。比较理想的人工饵料,应该是更多还原

【Abstract】 The activities of trypsin-like enzyme, pepsin and amylase were different in different digestive organs: liver>gastric>intestines. Activity of trypsin-like enzyme was about 14-60-fold higher than that of pepsin in the same tissue of juvenile and adult liver. The activity of amylase was about 500~1400-fold higher than that of cellulase. The activity of lipase was fairly low.The activities of trypsin-like enzyme, pepsin and amylase increased along with growth; but the activity of lipase did not change very much.更多还原
