the overwintering management basically stops feeding weever under the water temperature of 12 ℃, so that on the premise of ensuring that the specification does not exceed the standard, sufficient feed is fed as far as possible before the water temperature is reduced, a certain fertility degree of the pond is maintained during the overwintering period, fermented biological fertilizer can be stacked at four corners of the pond, the overwintering process is a continuous energy-consuming process, and a little feed can be fed properly at noon in a fine day;

the management in the high-temperature season is that the bottom of the bottom and the deteriorated water quality in the fish pond (13) are periodically discharged and changed by the sewage discharge mechanism (9) in the adult fish culture process, and at least 30 percent of fresh water is replaced;

in a high-temperature season, the surface water temperature is often over 30 ℃, weever can not eat the weever basically, and the water liquid in the fishpond (3) is cooled by the cooling mechanism;

disease prevention, in order to avoid disease breeding, splashing quicklime to the whole pond at intervals of about 15 days according to 10-15 kg/mu for disinfection and water regulation, the weever has high growth peak period and large food intake, is very easy to cause hepatobiliary syndrome, and vitamins and biological preparations for protecting liver and gallbladder can be added into the feed regularly.
