First, the surface of the water surface must ensure that the area of ​​2 acres or more, the water depth of 2 meters or more, adequate water, no pollution, good water quality. The bottom requires strong water retention and no leakage. We must do a good job of dredging and disinfection, remove some of the deposited sludge, and improve the bottom material. In the 7 days to 10 days before the fish species are stocked, the whole pool is sprayed and disinfected with the amount of lime of 75 kg to 90 kg per gram of water per metre. Poor conditions of the water should be equipped with aerator or water extraction machinery. Second, reasonable stocking is the first time in the culture. Generally, it is necessary to stock up before and after the beginning of spring, and it is also necessary to store warm-water fish in early May. Clear weather should be selected when stocking, to avoid freezing of fish species. The second is that the stocking species should be large. For fishing, the water should be stocked with large individuals, fast growing, and easy-to-fish species, such as carp, mackerel, squid, tilapia, freshwater white plover, small scales, and other species. Can also be based on local food and water conditions to determine the stocking species, rich in grassland can be the main grass carp, carp and other herbivorous fish; rich source of fertilizer can be the main carp, pupa, etc.; snails, crickets can be the main raising herring, Squid and so on. The third is a moderate amount of stocking. According to the conditions of the surface water and the feed conditions, the average weight per mu of water stocking more than 250 grams fish species 800 to 1000 tail. The fourth is flexible stocking methods. It can be used once to get enough time, catch in stages, catch large and stay small; it can be restocked for many times, catch by stages, catch up; it can also be supplemented with fishing, supplemented with fishing, to ensure that with the fishing, fishing value added . When stocking fish, they can be soaked with 4% saline or l0ppm bleach for 5 minutes to 10 minutes. Third, feeding and fertilizer feeding should be fed with compound feed. According to the living habits of fish, the use of wheat bran, rice bran, bean cakes, wine trough and minerals, vitamins made into a mixed feed, the average amount of feed per mu is about 1500 kg. At the same time, the cultivation of herbivorous fish such as ryegrass and Sudan grass is planted. Concentrates are fed twice a day, and the feeding amount is 2% to 5% of the total body weight of the fish, and the daily amount of green feed is 1 kg per kg of fish. The best place for feeding is to set up a feed station. The feed requires high quality, fresh, tasty and nutritious, and it is not allowed to feed mildewed and nutritious feeds. Pay attention to the application of fertilizer fertilizer. Water must be applied to the base before the fish is released. The amount of fertilizer can be determined according to the bottom quality and fertilizer type, generally 400 kg to 600 kg of manure applied to the manure, directly spread over the bottom of the pool. The top dressing must be enhanced during the growing season. Before May, the temperature is low, it is necessary to focus on cultivating plankton, fertilize once every 2 days to 3 days, and put 100 to 150 kilograms of perishable human and animal manure per acre; the temperature will rise gradually after May, and organic fertilizer will cause Pan pool, can be applied to inorganic fertilizer, top dressing once a week, each fertilizer per acre 3 kg to 5 kg.
