Winter fish ponds

First, raise the fish fingerlings and drain the pool water after the pond to remove excess silt. Kill 100 kg of lime per acre for disinfection and sterilization. Inject fresh fresh water into the river five days later to maintain a water depth of more than 1.6 meters. Each mu of cooked organic fertilizer 100 kilograms to 150 kilograms, fertilization water quality, cultivated fish per acre 200 kg to 250 kilograms. The water temperature is below 4°C, and it is fed once every 3 days to 4 days. The amount of feeding is 1% to 2% of the temporary fish. The water temperature is above 4°C and the feeding is performed every 2 days to 3 days. For 2% to 3%, feeding is performed once a day from March to April, and the amount of bait is 3% to 4%. During the maintenance period, every 7 days to 10 days, choose to replace the new water at noon. Change the water volume every time by 15 cm to 20 cm, and keep the water level stable. Sprinkle lime every half a month to disinfect the body of water to prevent fish disease. During the breeding period, prevention and control of water mould must be done. When the adults are stocked, they are washed with 3% salt water for 10 minutes to 15 minutes. It is found that the disease can spread 10 ppm of formalin to Quanchipia. After more than four months of support, the fish can produce more than 100 kilograms of fish per acre.

Second, cultured shrimp and fish ponds do not need medicine ponds, can directly into the fresh river water, keep the water depth of 1.2 meters or more, per acre applied maturity of organic fertilizer 100 kg to 200 kg, nurturing natural food organisms. Each species of acre stocking shrimp 20,000 to 25,000 tails, specifications 1.5 centimeters to 2 centimeters per tail, stocking time is appropriate in mid-December. Green prawns can ingest growth throughout the winter, and they need to catch two and feed in the middle of the feeding. That is, after feeding the shrimp for 20 days, the animal feeds such as fish gills and snail meat are mainly fed. About 3% of the amount of shrimp in the pond, from January to February, it is usually every 2 to 3 days to feed some bait at noon, and once in March, the amount of bait should be increased to 4% in April. May is the fastest growing season of the shrimp, the daily feeding amount increased to 6%, feeding 2 times to 3 times a day. During the breeding period, we must strengthen water quality management and discover that the water surface is frozen. It is necessary to promptly break the ice and increase oxygen, and prevent shrimp from suffocating due to lack of oxygen. By the end of May, most of the shrimps will have a size of 5 cm or more and can be sold as dried shrimps. (Xu Chengxu)
