适宜的投饵、施肥和酸碱度是养好池鱼的“三要素”,在养殖过程中有专业知识的人一般都会重视和使用。但也有人图省事或缺乏专业知识,就不根据“三要素”来实施科学养鱼,而是盲目的进行养鱼,结果导致池鱼不能正常生长,甚至发病死亡,这叫出力花钱讨损失。由实践得知,采用“三测”养鱼法是使池鱼正常生长,降低损失,夺取高产高效的好措施。一测水温适宜投饵:一般在水温8℃—31℃范围内水温越高,鱼儿摄食量越多,投饵量也相应越多,但不是越多越好,不要过量。若投饵过量,鱼类发病死亡的可能性增大。因此,投饵量必须根据四 Suitable feeding, fertilization and pH are the “three elements” of keeping fish ponds well, and those who have professional knowledge during the breeding process generally value and use it. However, there are also some people who save time or lack of professional knowledge. They do not implement scientific fish farming in accordance with the “three elements.” Instead, they blindly carry out fish farming. As a result, fish can not grow normally and even die. . Practice has learned that the use of “three test” fish law is to make the normal growth of fish, reduce losses, to seize the high yield and good measures. A water temperature suitable for feeding: generally in the water temperature of 8 ℃ -31 ℃ within the higher water temperature, fish feeding more, feeding the corresponding amount of more, but not the more the better, do not overdose. If over-feeding, the incidence of fish increased the possibility of death. Therefore, the amount of feeding must be based on four
