First, make preparations for stocking ponds should have good access to drainage facilities. Surrounded by ponds, nets and nets should be used to enclose walls that are 50 cm high.
Set up shrimp habitats in aquaculture waters, such as setting rubble, bricks, stones, mesh, old tires, grass dragons, etc., as shrimp nests to provide shelter for shrimps and to prevent predators.
Water plants such as water hyacinths, water peanuts, water lettuces, and white peony plants are planted around the pool, and their coverage is generally 1/3 of the surface of the pond, so as to facilitate lobster shade and breeding lobster-eating plankton.
General new lobster ponds can be used lime water with clear ponds, with 100 kg per acre, if the use of old ponds or lakes to raise lobsters, to dredging, trimming, exposure, 10 days to 15 days before stocking shrimps, with lime per acre 50 Kilogram dry pool disinfection. At the same time, it completely eliminates predatory wild predators such as cockroaches, clams, blackfish, and snakes and rats in ponds.
10 days to 15 days before the stocking of shrimps, generally, 100 kg to 200 kg of manure are thoroughly decomposed by applying pig manure to the surface of the water per mu, and plankton is cultivated and an appropriate amount of organic crumb is provided for shrimp feed.
Before the pond enters the water, it is better to install a water screen, preferably 60 mesh to 80 mesh, to prevent enemy water from entering. The depth of the pool water is kept between 50 cm and 80 cm, and the transparency is between 30 cm and 40 cm.
Second, stocking shrimp stocking shrimp should be carried out in the sunny morning and evening, stocking 2 cm long chicks per acre stocking 6000 to 8000 or 3 cm to 5 cm long shrimp 4000 to 6000 tails. The specifications for shrimps stocked in the same pond need to be neat and consistent. At the same time, about 50 grams of flowers can be stocked in pond water, 300 to 400 white pheasants and 200 breams.
3. After three days of careful feeding, put minced small fish and minced meat within 3 days, and put a small amount of mixed fish, minced meat, or compound feed within 3 days to 1 month until the shrimp grows to 6 cm~7. In centimeters, all of the crushed snails, corbicula and suitable vegetable feeds such as wheat, bran, corn, cakes, etc., or compound feeds may be fed. The amount of daily feeding is full, no food is left, and the medium and small lobsters are generally fed at 15%-20% of body weight. Adult shrimp are fed at 5%-10% of body weight. The food condition of the shrimp is adjusted. Feed 2 times a day, once in the morning and evening, and feed at 70%-80% of the daily feed at night. The feed should be distributed around the pond and properly dispersed. The lobster should be properly distributed in order to benefit the Feeding.
Fourth, water quality management Lobster grows fast, metabolism is strong, oxygen consumption is large, so the water quality of the shrimp pond should be kept fresh, add 15cm to 20cm deep water every week, to ensure that the water quality is fresh, clean, and there is enough dissolved oxygen, water transparency Above 35 cm depth, when the weather is overheating, it is necessary to properly deepen the pool water to stabilize the pool water temperature. Waterproofing is polluted by industrial pollution and pesticides.
When the water is low in dissolved oxygen, the water quality is aged, or the weather is thunderous and thundery in the thunderstorms, even in cloudy weather, the feeding amount should be reduced or the feeding should be stopped. Pay attention to observation. If the lobster is found to be unresponsive, swim to shore and float to the head. When climbing on the shore, it shows that the lack of oxygen is serious, and it is necessary to promptly add water or increase aerator oxygen.
V. Prevention of Diseases Diligent inspections should be carried out to ensure that the lobster's feeding, activities, growth, and clam shells are observed in order to take 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 pool, such as water mice, water snakes, water birds, frogs and fish, etc. If any, remove them in time.
Shrimp seedlings should be sterilized before surface treatment to prevent pathogens from being introduced into the pool. The shrimp ponds are regularly disinfected with quicklime, and new water is often added to keep the pool water clean and hygienic. A variety of vitamins are added to shrimp feed to enhance shrimp immunity. force.
Sixth, timely fishing is generally kept for two months or so. When the lobster weighs more than 50 grams, it can be caught and listed. The lobsters are caught in cages, cages, fences and other methods to catch large and small animals.
Set up shrimp habitats in aquaculture waters, such as setting rubble, bricks, stones, mesh, old tires, grass dragons, etc., as shrimp nests to provide shelter for shrimps and to prevent predators.
Water plants such as water hyacinths, water peanuts, water lettuces, and white peony plants are planted around the pool, and their coverage is generally 1/3 of the surface of the pond, so as to facilitate lobster shade and breeding lobster-eating plankton.
General new lobster ponds can be used lime water with clear ponds, with 100 kg per acre, if the use of old ponds or lakes to raise lobsters, to dredging, trimming, exposure, 10 days to 15 days before stocking shrimps, with lime per acre 50 Kilogram dry pool disinfection. At the same time, it completely eliminates predatory wild predators such as cockroaches, clams, blackfish, and snakes and rats in ponds.
10 days to 15 days before the stocking of shrimps, generally, 100 kg to 200 kg of manure are thoroughly decomposed by applying pig manure to the surface of the water per mu, and plankton is cultivated and an appropriate amount of organic crumb is provided for shrimp feed.

Second, stocking shrimp stocking shrimp should be carried out in the sunny morning and evening, stocking 2 cm long chicks per acre stocking 6000 to 8000 or 3 cm to 5 cm long shrimp 4000 to 6000 tails. The specifications for shrimps stocked in the same pond need to be neat and consistent. At the same time, about 50 grams of flowers can be stocked in pond water, 300 to 400 white pheasants and 200 breams.
