4. While sorting fish on the market, arrange for people to inject new water into the net fishing pond or turn on the aerator until after sunrise and then stop the water or machine according to the situation.
5. Due to the flooding of organic matter in the bottom caused by fishing and pulling NetEase, the whole pool can be sprinkled with about 5 kg of quicklime per mu according to the water quality, so that the organic matter caused by pulling net can flocculate and sink the bottom of the pool.
