The digestive enzyme activities were determined in Adriatic sturgeon and rainbow trout during starvation and refeeding period. Overall, the digestive enzyme activities are affected in the same sense in both species. The protease and lipase activities were decreased later than amylase activity. Even after 1 month of starvation, both species would be prepared to digest protein and lipids in an effective way. After 72 days of starvation, the digestive machinery of the sturgeon and of the trout shows an altered capacity to digest macronutrients. The capacity to digest proteins and lipids, after 60 days of refeeding, begins to become re-established in sturgeon and trout. In contrast, in this period, the capacity to digest carbohydrates remains depressed in both species.
在饥饿和重新投喂期间测定了亚得里亚海鲟鱼和虹鳟鱼的消化酶活性。总体而言，两种鱼类的消化酶活性受到的影响是相同的。蛋白酶和脂肪酶活性的下降晚于淀粉酶活性。即使在饥饿1个月后，两种鱼类仍能有效地消化蛋白质和脂质。饥饿72天后，鲟鱼和虹鳟鱼的消化机制显示出消化常量营养素的能力发生了改变。在重新投喂60天后，鲟鱼和虹鳟鱼消化蛋白质和脂质的能力开始重新建立。相比之下，在此期间，两种鱼类消化碳水化合物的能力仍然较低。
