(1) Pond conditions The pond area should be 8 to 12 mu, the water depth should be 2 meters or more, the water source should be sufficient and there should be no pollution, and the drainage system should be provided. Each pond should be equipped with a 1.5-kilowatt impeller type aerator. The ponds were reconstructed and cleared before the fish species were released. The sediment was kept 15 to 20 centimeters long and ploughed and exposed to the sun, and then disinfected with fresh lime ponds. (2) Feeding of fish fingerlings in the end of March. The stocking is carried out in late March. The temperature is about 15°C, and 800 mu are used. The specifications are 50-80 g/tail, and 3% salt water is used for dipping and disinfection before lower ponds. . The carp stocking is conducted in early April. There are 120 white pheasants and 30 breams on the acre. The specifications are about 50 grams/tail, and 20 milligrams of potassium permanganate is used for sterilizing after stocking. (III) Feeding and management 1. The breeding method adopts artificial domestication to enable the catfish tails to fly up and snatch, and use the method of fixed feed and regular casting. Artificial fish feeding and domestication began on the third day after stocking. Because the catfish tail likes low-light feeding, domestication should be performed after dawn and sunset, twice a day, after 10 days or so, it can be basically domesticated. Then start normal feeding, follow the "slow-fast-slow, less-more-less" principle. Feeding amount can be adjusted according to the fish's eating and feeding conditions. When more than 80% of the fish are fed and walked away, they can stop feeding. Each feeding time is about 30 minutes. The high temperature season takes a small number of multiple feeding methods, and the general daily investment. 4 to 6 times. 2. In the early stage of water quality management, from March to May, the depth of water can be maintained at 1.2 meters, changing the water every 4 to 5 days, changing the water for about 15 centimeters each time, and maintaining the transparency more than 25 centimeters; and maintaining it more than 2 meters from July to September. The full water level, 2 to 3 days of water change 1, transparency to maintain more than 30 cm. Adhere to the sunny day at noon to open aerator for 1 to 2 hours, rainy days or thunderstorms, and at night or early in the morning to start aeration machine anti-floating head pan. 3, fish disease prevention and prevention adhere to the principle of prevention and control. From May to September, 30 g/m3 of quicklime and 0.1 g/m3 of dibromohydantoin are disinfected once a month; at the end of April, insecticides are carried out with insecticide; Due to the disinfection of the feeding area. In autumn, the pond water temperature changes greatly, and the nitrite content will increase. Water quality protection antidote should be used to degrade the nitrite content in water. 4, timely fishing August high water temperature prone to hypoxic floating head, should be the majority of fish caught on the stock market, while stocking the corresponding number of summer eel fry. Reduce the amount of fish on the pond and reduce the consumption of dissolved oxygen. Batch fishing, listing and processing began in October.
