Pond high-yield culture method

In order to change the current situation of low yields of shrimp cultured in ponds, the author has adopted a series of techniques such as one-year double-season shrimp rearing and feeding of full-priced pellet feeds to achieve better economic benefits for the aquaculture. The main technical points are now described as follows: Pond requirements. Prawns have high oxygen consumption and are not tolerant to hypoxia. At the same time, they are also benthic animals and have poor swimming ability. They like to move at the bottom of the pool. Therefore, the pond area for cultured green shrimp should not be too large. Generally, the pond area for shrimp cultivation is 3-8 mu, the slope ratio is 1:3 to 1:3.5, the water depth is about 1.5 meters, there is no silt at the bottom of the pond, and the water source is not polluted. Meet the national fishery water standards. The first half of the seedlings were thoroughly cleared with quicklime and installed in each pond. 2. Seed source. Green shrimp seedlings are purchased as natural seedlings, and trout and sturgeon fish species are purchased from local fish farms. 3. Planting plants. Green prawns are crustaceans with shelling and mutual disability. Therefore, in order to avoid the phenomenon of mutual disability of the green prawns, suitable plants must be planted to prevent the shrimps from interfering with each other. There are two main types of plants for water plants: one is water peanuts planted around shallow waterways near the pool; the other is submerged plants planted at the bottom of ponds with shallow water, with black-leafed black algae, Elodea, etc. Rapid, so when there are too many plants in the pond, the sparse water can be removed by artificial means, so that the distribution of aquatic plants in the pond is the best. Under normal circumstances, the proportion of watergrass growth area to the total pond surface area should be controlled at about 30%. 4. Set up the mesh. In the middle of the shrimp pond, 10 to 33 mesh unscented summer flower nets are set, fixed with a bamboo frame, and set at a height of 20 to 40 cm below the surface of the water, with a gradient of 15 to 20 degrees so that the shrimp can crawl up and down. The width of the film is 3 to 4 meters, and the length is determined by the pool. Generally, about 5 acres of ponds can have 2 rows of mesh. 5. Seed stocking. The growth rate of shrimp is fast, and the breeding cycle is short. In the case where the culture environment is appropriate and the feed is sufficient, the shrimp seedlings can reach a commercial specification of 3 grams or more per rearing after 2 months of culture. Therefore, two breeding modes of spring and summer and two-year-old breeding can be adopted. Summer stocking is conducted around July, and about 40,000 to 60,000 shrimps per acre of about 1 cm are placed on the mu, and a small amount of carp species is released after 10 to 20 days. When stocking, they must have neat specifications and a strong physique. The stocking time should be selected when the morning is sunny or when the cloudy days are not sultry, and the seedlings should avoid the peak of shelling during stocking. By the end of August-September, there will be a batch of spawning hatchlings of small shrimps. These shrimps can grow to 2 to 3 centimeters by the end of the year. They can be used as spring stocking seedlings, and usually have 30,000 to 50,000 mu. tail. 6. Feeding management. According to the feeding habits of the shrimp, adhere to the principle of feeding. Normally, it is fed twice a day for 8 to 9 hours and 5 to 7 in the morning, and the total amount is 1/3 in the morning and 2/3 in the afternoon. The bait should be thrown in a shallow area with long aquatic plants, and evenly distributed. The daily feed rate of shrimp seedlings is generally controlled at 3% to 5%, and it is mainly fed with fine-grained feeds. With the increase of individual shrimp, appropriate pellet feeds can be fed. When feeding, observe carefully the eating conditions of the shrimp. Usually, the amount of each feeding should be within 2 to 4 hours. 7. Water quality management. In the hot season, it is necessary to add water or change the water once a week, drain the bottom old water first, and add 15 to 20 cm deep new water. At night or in the early morning, the floating head of the shrimp must be found. The aerator must be opened and the new water must be filled. Especially in the weather before the sweltering heat or thunderstorm, measures should be taken to add water and change the water 24 hours a day to keep the pool water flowing. 8. Daily management. Every half month disinfect the water with quicklime or dibromohydantoin, chlorine dioxide and other disinfectants to kill pathogens and pathogens. At the same time observe whether the ciliate body attached to the green shrimp, can be used Quanchiposa copper sulfate aqueous solution, the whole pool of the concentration of 0.7ppm, every 7 days and then again. 9. Get caught at a proper time. Green shrimp grow up to 4 to 5 centimeters can be arrested and listed. General spring release seedlings from May to July from the listing, summer seedlings from September to November to catch the listing. Planting aquatic plants and nets in ponds is an effective measure to increase the survival rate and yield of green shrimp. It is conducive to the growth, life, and concealment of clams, and can make full use of water bodies to increase the yield of green prawns. However, it should be noted that the transplanted weeds should include submerged aquatic plants and buoyant aquatic plants, and the area should also reach an appropriate proportion. Mixed pond whitefish in the pond is not only conducive to the use of water space, but also conducive to water quality regulation, but also increased fish production and economic benefits. Adopting the double-season breeding mode can improve the utilization rate of ponds and the economic benefits of the cultivation of shrimps, because winter and spring are released in January and captured in June; in summer and autumn, they are released in July and harvested before the Spring Festival. Ponds are used throughout the year to increase the economic benefits of shrimp culture.
