The high-density culture of shrimp can capture high-yield culture and improve the efficiency of the pond. The main points of introduction of the 200 kg per mu shrimp breeding technology are as follows:
I. Selection of Ponds Ponds with an area of ​​1,000 square meters and a water depth of 80 to 120 centimeters are required to provide convenient water and electricity supply, and to prevent flooding and prevent enemy encroachment.
Second, the drug clear pond use Qingtang net or quicklime and other drugs for dry pond clear pond. After entering the water for 7 to 10 days after clear pond, it is necessary to pay attention to filtration when entering the water to prevent the enemy from entering.
Third, aquatic plants cultivated shrimp ponds with rotating leaves black algae, sub-subtropical vegetables such as sub-descilents. The planting density should be moderate, about 40% of the water surface can see the bottom of the pool, and the aquatic planting should be distributed in a massive distribution. If aquatic peanuts are planted, the amount of breeding should be strictly controlled to prevent over-coverage. Before the plants enter the pool, they must be soaked with drugs to kill pests in the grass.
Fourth, the stocking rate of shrimp species for stocking is 20,000 to 4000 kilograms per kilogram. It is best to choose self-breeding and self-cultivation shrimp species, and strive to be neat with the pool specifications. Restocking time is in early April or late July. It can be listed on the farm for about 80 days, and it can be raised for two years. Each mu can produce more than 200 kilograms of shrimp that is about 5 centimeters in size.
Fifth, the food is fed to the shrimp. The food intake is small, the growth rate is fast, and the bait reward is high. In the premise of ensuring sufficient aquatic plants, the amount of feeding per mu per day is 2 to 4 kg. The bait is suitable for self-mixed bait. With bean cake powder, cake flour plus bran and a small amount of screw meat mud (with shell crush) or fish meal (pulp) mixed. Feed 2 times a day, early morning and evening, more scattered, regularly feeding.
6. Water Quality Management During the entire breeding period, we must always seize the oxygenation link and effectively strengthen water quality management. The aquaculture pond must be equipped with air pressure oxygen-enhancement equipment with enough power (1 kilowatt-hour per acre) to ensure that the pool is rich in dissolved oxygen. In addition, we must pay attention to the day-to-day management of disease prevention, anti-virus, and escape prevention.
