Silurus meridionalis can tolerate hypoxic water, but that doesn't mean they don't need to pay attention to water quality. Long-term aquaculture practice has proved that good water produces good fish and good water produces big fish. Poor water quality can easily cause fish diseases. Even if catfish has strong disease resistance, it is impossible to survive in the deteriorating water environment without getting sick and dying. To change the water regularly, you can change the water once every 15 days or so, and the amount of change is 1/3 of the pond water. Pay attention to feeding. Catfish is a gluttonous fish, which eats a lot, so we should pay attention to quantification when feeding.
Quantitative feeding, you can weigh some fish regularly, and then feed them according to 5% ~ 8% of the fish's weight. Feeding too many catfish will cause gastrointestinal and hepatobiliary diseases and increase the cost of breeding. Artificial culture of Siniperca chuatsi can be fed with animal feed such as fly maggots and silkworm chrysalis, and can also be fed with plants such as rice bran and peanut cake. Generally speaking, we breed in ponds. There are abundant water resources around the pond, which is convenient for drainage and water exchange. We repaired the bottom of the pool and arranged an escape net at the entrance and exit. Some aquatic plants can be planted around the pond to purify the water and provide shade.
