本文以酶学分析方法测定了凡纳对虾状幼体,糠虾和仔虾三个发育期淀粉酶和脂肪酶的活力。实验结果表明,糠虾期淀粉酶比活力显著高于状幼体和仔虾两期(P<0.05);脂肪酶比活力状幼体显著高于糠虾幼体(P<0.05)。在食性转化过程中,凡纳对虾幼体消化酶活力与其食性相适应,不同发育阶段消化酶调节机制不同。
In this paper, enzymatic analysis was used to determine the vitality of amylase and lipase in three developmental stages of Litopenaeus vannamei, shrimp and shrimp. The results showed that the amylase specific activity in the shrimp stage was significantly higher than that in the juvenile and larvae (P <0.05). The specific activity of the lipase was significantly higher than that in the shrimp (P <0.05). During the process of food conversion, the digestive enzyme activity of Litopenaeus vannamei was adapted to its diet, and the digestive enzymes in different developmental stages had different regulatory mechanisms.
