投饵量、施肥量和酸碱度可以说是养好鱼的三要素。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,是降低鱼类发病率夺取养鱼高产的有效措施。其具体方法是:1 测水的温度定投饵量。一般来说,在7—32℃的适温范围内,水温越高,鱼的摄食越强,投饵量也越大。但不是越多越好。如不适量,投饵越多,鱼的发病率和死亡率也越高。为此,必
The amount of feed, fertilizer and pH can be said that the three elements of 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 lead to the death of fish but also increase the cost of raising fish. Practice has proved that using the “three test” method of fish farming new technology is to reduce the incidence of fish to capture high-yielding fish effective measures. The specific method is: a water temperature measuring the amount of feeding bait. In general, the optimum temperature range of 7-32 ℃, the higher the water temperature, the stronger the fish feeding, the greater the amount of feeding. But not the more the better. If not, the more you feed, the higher the morbidity and mortality of fish. For this reason
