夏秋季节,鱼塘里的浮游动物进入生长繁殖旺盛时期。山区鱼塘由于树木或高山挡住了阳光,鱼塘光照时间缩短,浮游植物的生长和繁殖缓慢,导致浮游动物和浮游植物之间的生态平衡遭到破坏,直至整口鱼塘“清澈见底”,防治不及,往往会造成鱼产量低下。
In summer and autumn, the zooplankton in the fish ponds enter the period of vigorous growth and reproduction. Mountain fish ponds block the sun by trees or high mountains, fish ponds shorten the light time, phytoplankton growth and reproduction is slow, resulting in zooplankton and phytoplankton ecological balance between the destruction until the entire pond “crystal clear” , Prevention and control, often result in low fish production.
