鱼类的饲养技术中最为重要的技术之一,就是投饵技术。投饵是养殖活动中每天都进行的最为直接的生产技术。投饵技术包括投饵的多少,投饵次数,投饵方法等,不仅直接影响鱼类的生长和产量,而且还给养鱼的饵料效率和经济效益以很大的影响。特别是象商品鱼基地的池塘养鱼和围拦、网箱、流水养鱼等高度集约化的养殖。在天然饵料的作用极其微小,鱼类的生长几乎完全依靠人工投饵施肥的情况下,投饵技术就显得更为重要。我们通常所说的合理投饵,就是要根据饲养对象的要求和环境因子(主要是水温、溶氧)的变化,确定适当的投饵量和投饵次数,既要均衡地满足鱼类对营养物
One of the most important techniques in fish feeding is feeding technology. Feed is the most direct production technique that is practiced daily in farming activities. The techniques of feeding include the amount of feeding, the number of feeding and the method of feeding, which not only directly affect the growth and yield of fish, but also greatly affect the efficiency and economic benefits of feeding the fish. In particular, fish ponds, such as fish ponds at the base of commodity fish, and cages and aquaculture water are highly intensively cultivated. In the extremely small role of natural food, fish growth almost completely rely on artificial feeding of fertilizers, feeding technology is even more important. We usually say that reasonable feeding is based on the requirements of rearing objects and environmental factors (mainly water temperature, dissolved oxygen) changes, to determine the appropriate amount of feeding and feeding frequency, it is necessary to balance the nutrition of fish Things
