Pond requirements. Adequate water supply, convenient drainage and drainage. The area generally does not exceed 4 acres and the water depth is 1-1.5 meters. The bottom of the pool is less silt.
Water quality conditions. Green shrimp are particularly sensitive to toxic chemicals such as "6-66" and "enemy-killing". Therefore, aquaculture water should be fresh and pollution-free.
Clear pond, disinfection. In order to meet the needs of pollution-free culture, the use of tea seed cakes and crotons in the cultivation of clear-tank culture clear ponds is ideal, and sodium pentachlorophenol should not be used. How to use Croton: The pond with an average depth of about 10 cm should use 5-7 kilograms of croton per acre. Grind the croton into a paste and put it into a container before use. Add 100 grams of shochu or 750 grams of salt for 3 days. Dilute it with pool water and spill the scum with juice. After 10 to 15 days, deepen the pool water to about 1m to put the shrimps (filtered with fine mesh net cloth when water injection). Tea seed cake use method: Keep the water depth of 0.5 meters, the fresh tea seed cake evenly spread in the pool, so that the pool water was 1010-6-1510-6 concentration, 15 days after the water to 1 meter deep, put the shrimp seedlings.
Shrimp stocking. Before ponds are stocked with shrimp, 250-300 kg of organic fertilizer is applied in Mushi, and shrimps can be stocked when a large number of food organisms appear. The stocking of 60,000 to 100,000 shrimps per acre requires the uniform size of the shrimps, and the body is strong and disease-free, and the appendages are intact. Note: The stocking should be carried out in the early morning or early evening. The water temperature difference must not exceed 2°C.
Set shrimp nests. Setting the shrimp nest can make the shrimp three-dimensionally use water bodies. The shrimp nest can be made of shabby mesh, poplar root, brown, pine branches, etc. In addition, it is best to plant aquatic plants in the water, such as Vallisneria, black algae, water hyacinth, etc. It should be noted that the area of ​​aquatic plants cannot exceed 1/3 of the shrimp pond area.
Feeding. Feeding once in the morning and evening, the daily feed amount does not exceed 10% of the shrimp body weight. In the morning, where the water level is slightly deeper (because the shrimps are afraid of strong light), they are thrown in the shallows of the pond in the evening (the feeding amount accounts for 70% of the whole day).
