投饵量、施肥量和酸碱度是养好鱼的三要素。但不少人在养鱼过程中,不是根据水的温度、透明度和酸碱度科学地投饵、施肥,而是盲目地投施,结果既导致鱼类生病死亡,又增加了养鱼成本。实践证明,采用“三测”法养鱼新技术,是降低鱼类发病率、取得养鱼高产的有效措施。具 The amount of feeding, fertilizer and pH are three elements of raising a good fish. However, in the process of raising fish, many people do not feed and fertilize scientifically according to the temperature, transparency and pH of water. Instead, they blindly resort to fish. As a result, they not only cause the fish to die but also increase the cost of raising fish. Practice has proved that the use of “three test ” method of fish culture new technology is to reduce the incidence of fish, fish and obtain an effective measure of high yield. With
