要改进仔鱼的人工饵料配方,首先必须测定其天然饵料生物体内的营养水平。对鱼类天然饵料生物的化学测定并不一定能说明这种饵料适合于鱼的每一个个体发育阶段(仔鱼、幼鱼、成鱼)的营养要求。用褶皱臂尾轮虫(Brachionus plicatilis)和卤虫无节幼体喂养1~2克的鲤幼鱼时,从蛋白质效率(PER)和纯蛋白质利用率(NPU)的基础测定来看,营养价值不如干酪素,但用酪蛋白
To improve larval artificial feed formulations, it is first necessary to determine the level of nutrition in their natural food organisms. The chemical determination of natural fish food organisms does not necessarily indicate the nutritional requirements of the food for each individual developmental stage of the fish (larva, juvenile, adult). When feeding 1 to 2 g of carp juvenile with Brachionus plicatilis and Artemia nauplii, the nutritional value was not as good as the basal determination of protein efficiency (PER) and pure protein utilization (NPU) Casein, but casein
