First, pond preparation
1. Shrimp tank selection; Qingpen pond selection of good ventilation performance, adequate water supply, drainage and irrigation facilities and water pollution-free ponds.
2. shrimp pond area: generally about 5 acres is good, shrimp pond slope ratio is generally 1:2.5-3; water depth is 1.2-1.5m; flat bottom, mud requirements below 10cm.
3, inlet and outlet facilities: shrimp ponds into the water at the entrance of 40 mesh and 60 mesh two screen mesh screen to filter the water, the drain port is closed with a dense mesh or wire mesh to prevent the shrimp escape.
4. Equipped with a 1.5kW aerator in each shrimp pond.
Second, aquatic planting and mesh set
This is a key measure for the three-dimensional culture of green shrimp. According to the biological characteristics of the shrimp, in addition to planting a certain area of ​​aquatic plants around the shrimp ponds every year, in the middle of the shrimp ponds, a certain area of ​​summer flower nets is set to increase green The habitat of shrimp is:
1. Transplanting water plants: Water plants such as peanuts, water spinach, and water lilies are planted around the ponds in the shallow water zone about 1m away from the pond. The grass has a width of about 1m and the area accounts for 10% to 20% of the surface of the pond. When aquatic plants grow vigorously in summer, they must be properly controlled for removal. The first thing to cultivate aquatic plants is to create a good habitat and a hidden place for the shrimps to avoid mutual food. The second is to reduce the temperature of the water in the hot season and avoid direct sunlight, which is conducive to the growth of shrimp. The third is to make the pool water fresh and stable, adequate dissolved oxygen, and control the floating head of the shrimp. The fourth is to make full use of the pond space to provide fresh plant food.
2. Mesh setting: In the middle of the pond, a double or single layer of mesh is used to build a row or two rows of inhabitants, and the bamboo frame is “^†type fixed, occupying about 25% of the total area of ​​the pond, two layers of mesh With a spacing of about 30 cm, the upper mesh grafts cover the top of the water spinach, allowing the root system to extend through the second layer mesh and serve as a clam shell for the shrimp. Habitat and feeding provide good environmental conditions. Mesh mesh is a 10-33 mesh summer festival mesh.
Third, shrimp stocking
l. Preparation: 0 days before stocking, 0 days, 75kg - 100kg fresh lime pond disinfection per acre.
2. After 4 days, the clear pond is filled with water, the water depth is 50cm-70cm, and 150kg-200kg manure is applied per mu to cultivate plankton.
3. Shrimp stocking: In the middle and late June, choose a cloudy or sunny morning stocking shrimp, stocking density of 20,000 to 40,000 per acre, specifications of more than 1.5m.
4. After half a year of stocking, set the flowers and fishes with 55 tails/mu.
Fourth, feed feeding
1. Fresh shrimp prefers bean cakes, bran, flour, and animal foods prefer to eat oysters, snails, miscellaneous fish, fish meal, etc., according to 30% - 40% animal feed, 60% - 70% plant The bait is formulated into a pellet feed with a particle size of 2 mm to 4 mm.
2. Feeding time and quantity: Feeding once every 8 o'clock in the morning and around 5 o'clock in the afternoon. The amount of feed in the morning accounts for 30%, the amount of feed in the afternoon accounts for 70%, and the daily feeding amount is generally controlled by the total weight of the shrimp. 3%-5%.
3. Feeding method: Distribute evenly in the mesh in the pond, or in the shallows around the pond.
4. From September to early October, freshly ground snails were fed once a day. The daily feed amount was about 10% of the total body weight of the shrimps to enhance the fattening effect.
V. Shrimp pond management
1. Shrimp pond water quality: The shrimp pond should keep fresh water, adequate dissolved oxygen, but also have a certain degree of fatness, transparency is controlled at about 40cm. Regular water injection methods are used to regulate water quality, with less water injection in the early stage, and water injection in the middle and later stages to keep the water quality fat, live, tender and cool. Appropriate application of phosphate fertilizer, promote the growth of plankton. In the summer, the injection and replacement of water can be enhanced. Each injection of water is 10-20 cm. If the water quality is too fat, some of the pool water may be drained and then filled with water.
2. To eliminate enemy predators often: every 15 days to 20 days in the shrimp pond, use quicklime 20kg/mu?m Quanchiposa, to achieve bactericidal calcium. Adjust the role of water quality.
3. Day-to-day management: Stick to the morning and evening patrol ponds, observe the shrimp's food, oyster husk, growth, activities and dead shrimps, and do a good record of patrol ponds. In the hot summer, we must increase the number of patrols in the morning and evening. If we find that the side of the shrimp is on the side of the water, on the grass or on the side of the pool, it indicates that the pool water has been deprived of oxygen, and it should be filled with water or an aerator to rescue it.
VI. Disease Prevention
The shrimps have stronger resistance to disease and less incidence, and are mainly based on disinfection and prevention. In practice, we mainly use quicklime to sprinkling lime, which is usually applied twice every 7 days to 10 days. Each time we use 10kg/mu, the quicklime is used as a slurry for the Quanchiposa. This will not only disinfect the disease, but also increase the calcium in the water. Good for shrimp oysters.
Seven, shrimp fishing
In the middle and late November, the shrimps can begin to be gradually listed in batches, adopting multiple rounds of catching and catching large and small measures to increase output value.
Green shrimp often live in rivers, lakes, reservoirs, ponds and other freshwater waters. It is a new breed of pond culture that is currently advancing the adjustment of industrial structure. In 2001, Gushi County, Henan Province, raised 2,000 mu of freshwater shrimp and used three-dimensional breeding techniques. It has achieved very good results, so that the majority of farmers have obtained considerable benefits in the year. In 2002, the number of shrimp farmers in the county was greatly increased, which promoted the adjustment of the industrial structure. In this regard, we have summarized the experiences summarized in practice as follows:
