What if there are dead fish in the fish pond after throwing pig manure?

No matter pig manure or chicken manure, raw manure can not be directly put in, because manure contains a lot of organic matter, which naturally ferments in water to produce high temperature, killing fish. On the other hand, pig manure is relatively fat and salty, which is also a reason. Therefore, pig manure and chicken manure should be fermented before running water, so that there will be no decomposition of organic matter, so it will not be cooked at high temperature. Now many people ferment pig manure and chicken manure. A package of 200 grams of Qiangxing compost starter can ferment one ton of pig manure, and it will be completely decomposed in about 10 day. Fermented pig manure is tasteless, loose and has white hyphae, which is helpful to raise fish and fertilize water.
