鱼浮头即是当水中溶氧量减少到一定程度时,鱼类呼吸困难,浮于水面吸氧。如果溶氧量继续下降,终会出现窒息死亡。一、浮头的原因(一)水质变坏。实行密养混养后,密集的鱼类和大量的浮游生物、底栖生物等呼吸需要消耗氧,它们排出的粪便及其他有机生物在分解过程中消耗大量的氧引起浮头。(二)池水过肥。底质积存有机质过多,在高温下使池
Fish floating head is when the amount of dissolved oxygen in water reduced to a certain extent, the fish breathing difficulties, floating in the water oxygen. If the amount of dissolved oxygen continues to decline, suffocation will eventually death. First, the reasons for the floating head (a) the deterioration of water quality. After the intensive culture and polyculture, dense fish and a large number of plankton, benthic organisms and other respiratory need to consume oxygen, their excretion of feces and other organic organisms in the decomposition process consumes a lot of oxygen caused by floating head. (B) the water is too fat. Endoplasmic accumulation of organic matter too much, the pool at high temperatures
