众所周知,降低鱼类饵料中蛋白质的含量、增加糖的含量,会使饵料成本降低,有利于鱼类养殖事业的发展。但饵料中糖的含量超过鱼类能够适应的限度,不但会造成浪费,而且会使鱼类的生长速度放慢,死亡率增高。因此,知道饵料中的最适糖含量对确定养殖鱼类的最佳饵料配方是必不可少的。评价鱼类对饵料中糖含量适应能力的大小,除了要知道与消化吸收有关的酶的适应情况外,更重要的是要
It is well-known that reducing the protein content of fish food and increasing the sugar content will reduce the cost of food and contribute to the development of fish farming. However, the content of sugars in the food exceeds the limit that the fish can adapt to, which will not only cause waste, but also slow down the growth of fish and increase the mortality rate. Therefore, it is essential to know the optimal sugar content in the feed to determine the best feed formula for farmed fish. In addition to assessing the adaptability of fish to dietary carbohydrate content, it is more important to know the adaptation of enzymes involved in digestion and absorption
