为了证明鱼摄食后活性消化酶连续的变化,作者报道了鲤鱼每日给食一次时消化酶活性的变化。判断摄食后消化酶的分泌和失活以及分泌液的合成之间的相互作用。本文论述了鲤鱼在每日给食两次时蛋白酶和淀粉酶活性的连续变化性,并与每日给食一次时酶活性作比较。材料和方法实验鱼。1龄鲤鱼146尾,平均体重63克,分成三组,即A、B_1和B_2。在水簇箱里用200升25℃的循环水体饲养十天。A组每天上午9:00给食一次,B_1和B_2组每天上午9:00和下午2:30给食两次。各组给鲤鱼投喂商品颗粒饵料,每次大约吃三十分钟,直到鱼吃饱。十天后,待鱼适应了新的环境,在上午喂食以前从A组随机取鱼5尾,并且以一定的时间间隔连续
In order to demonstrate the continuous variation of active digestive enzymes after fish feeding, the authors reported changes in digestive enzyme activity when carp was given once daily. To determine the interaction between the secretion and inactivation of digestive enzymes after ingestion and the synthesis of secretions. This article discusses the continuous variability of protease and amylase activity in carp twice daily, compared to the enzyme activity when given once daily. Materials and methods Experimental fish. One hundred and forty-six carp, average body weight of 63 g, were divided into three groups, namely A, B_1 and B_2. Raise for 10 days with 200 liters of 25 ° C circulating water in a water box. Group A was given daily at 9:00 a.m., Group B_1 and B_2 were given twice daily at 9:00 a.m. and 2:30 p.m. Each group fed commercial carp particle food, each about eat thirty minutes, until the fish eat full. Ten days later, the fish were adapted to the new environment, five fish were randomly taken from group A before feeding in the morning, and were continuous at regular time intervals
