Green prawns are the largest freshwater shrimp in China. They are delicate, delicious, and nutritious and are favored by people.
One of the breeding methods is to directly stocking fresh shrimp, with 500 to 800 females per acre and 300 to 500 males, which should be stocked at the end of April and beginning of May.
The second is to stock artificially cultivated juveniles. First, use 1 mu of pond as a breeding pond. Before the beginning of summer, catch 10 to 12.5 kilograms of pelagic shrimp from the river, and select individuals with strong, fertile eggs into the pool. , Put the grass or poplar root in the pool. During the morning of the production period, a small bucket (about 1 kilogram of soybeans) is soaked in milk, and a barrel of cake or syrup (about 5 kg of dried product) is poured. 20 days after the hatching of the juveniles, the size of the rice grains can be grown and the fish can be stocked. With this method, 2.5 million juvenile shrimps can be bred per acre. Artificially reared fresh shrimp, the yield per mu can reach 15 to 25 kilograms, and high yield can reach 40 to 50 kilograms. The food supply of the shrimp is more complex. In artificial feeding, various artificial feeds can be fed, such as silkworm cocoons, fly pupae, and fish meal. The plant feeds include bean cakes, rice bran, wheat bran, and distiller's grains. The feeding time is appropriate at 5 pm, and it can be evenly sprinkled around the shrimp ponds in appropriate quantities so that the shrimps will not kill each other due to hunger.
Pond Management Artificial culture of shrimp should be built shrimp ponds, can use the general fish ponds, an area of ​​2 to 6 acres, depth of 1.2 to 1.5 meters, flat sand bottom, silt should not be too much. The shrimp pond should be close to the water source for convenient drainage and irrigation. The swimming ability of shrimp is poor. In the shrimp pond, some algae and other submerged plants should be produced for shrimps to inhabit, but the area should not exceed 25% of the water area. Branches can also be used for stealth shrimps to prevent shrimp from suffering losses. In order to prevent pool collapse, leakage, or waterfowl and water mice preying on the green shrimp, the Qingpen pond must be strengthened. Once a large number of prawns are found to jump, swim on the surface of the water, or lie on the edge of the pool, it means that the dissolved oxygen in the water is low, and the metabolites are too high, which will cause a large number of deaths of the prawns. The water must be changed immediately to increase oxygen.
