随着气温的逐渐升高,一些静水养鱼的池塘很容易发生“泛池”,“泛池”的主要特征是鱼儿严重浮头或窒息死亡。其主要原因是鱼池在上一年的秋末投饵施肥过量,池底沉积有机物过多,同时,池水中积存了鱼类一个冬季的排泄物,严重污染了水质,加之池水不流动,气温升高,细菌大量繁殖,沉积的有机物急剧分解,消耗了池 As the temperature gradually rises, some “pan-pool” ponds are prone to hydrostatic aquaculture. The main feature of the “pan-pool” is the severe floating or suffocation of fish. The main reason is that the fish pond was over-fertilized in the late autumn of the previous year with too much organic matter deposited on the bottom of the pond. In the meantime, a winter excrement of fish was accumulated in the pond water, which seriously polluted the water quality. In addition, the water did not flow and the temperature rose , Bacteria multiply, sedimentary organic matter decomposes rapidly, consuming the pool
