On the 24th and 48th day, at the same salinity, the protease and amylase activity in descending order were as follows: pyloric caeca, intestine, stomach and liver;

第24天和第48天，在同一盐度下，各消化器官蛋白酶活力和淀粉酶活力高低顺序依次均为：幽门盲囊、肠道、胃和肝脏；

Under the same protein level, the protease and lipase activities of stomach, intestine and pyloric caeca in 18% lipid level groups were slightly higher than those in 9% lipid level groups.

同一蛋白质水平下，18%脂肪水平组胃、肠道和幽门盲囊的蛋白酶和脂肪酶活性均略高于9%脂肪水平组。
