The first is to prepare well for stocking: Ponds must have good access and drainage facilities. Surrounded by ponds, nets and nets should be used to enclose walls that are 50 cm high. General new lobster pond can be used lime water with water clear pond, with 100 kilograms per acre, if the use of old ponds or lakes to raise lobster, to dredging, trimming, exposure, 10-15 days before stocking shrimp, 50 kg per kilogram of lime Dry pool disinfection. At the same time, it completely eliminates predatory wild predators such as cockroaches, clams, blackfish, and snakes and rats in ponds. Ten to 15 days before the stocking of shrimps, generally 100-200 kilograms of manure is fully decomposed with pig manure applied to the water surface of the mussels, and plankton is cultivated and an appropriate amount of organic crumb is provided for shrimp feed. The second is the stocking of shrimp: The stocking of shrimp should be conducted in the morning and evening on a sunny day, with 2,000-8,000 tails of 2 cm long larvae or 4000-6000 tails of 3-5 cm long juveniles. At the same time, about 50 grams of flowers, 300-400 white storks, and 200 squid can be stocked in pond water. Third, water quality management: The water quality of shrimp ponds should be kept fresh, and water should be added 15-20 cm deep every week to ensure that the water quality is fresh, clean, and there is enough dissolved oxygen, and the transparency of the pool water is controlled to be more than 35 cm deep. Waterproofing is subject to industrial pollution, pesticide pollution and chemical pollution. The fourth is to prevent disease: should be diligently inspected, diligently patrol ponds, pay attention to lobster foraging, activities, growth and clam shells, etc., in order to take the necessary technical measures in a timely manner. Remove moss in the pool in time; always check the inlet and outlet filters to prevent worms or wild fish and other harmful organisms from entering due to broken filters. Always pay attention to whether there are predator organisms in the pond, such as water mice, water snakes, etc., before surface disinfection of shrimp seedlings.
