浮萍是草、鳊鱼的好饲料,但投喂不当对渔业生产反而有害,必须要注意以下三点。(一)不让浮萍覆盖整个鱼池水面。向鱼池投放浮萍数量过大,甚至覆盖了整个水面,极易造成池水严重缺氧。最好在鱼池的一边圈一片水面作食场,将浮萍投在食场内,不让其满池飘浮。食台面积不能超过鱼池面? Duckweed is a good feed for grasses and anchovy, but it is harmful to fishery production if it is not properly fed, so we must pay attention to the following three points. (A) do not let duckweed cover the entire pond water. Duckweed to the fish pond is too large, or even cover the entire surface of the water, can easily lead to a serious shortage of water oxygen. It is best to circle the surface of a fish pond for food, the duckweed in the food court, not to let its full pool floating. Food Taiwan area can not exceed the fish pond surface?
