How to raise lobster?
Ponds must 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 installing rubble, bricks, stones, mesh, used tires, grass dragons, etc. as shrimp nests for shrimp shelter and hostile defense.
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 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.
Before the pond is filled with water, it is best to install a water screen that is 60-80 mesh to prevent the water from entering the enemy. The depth of the pool is maintained at 50-80 cm and the transparency is between 30-40 cm.
Second, stocking shrimp
It is advisable for free-range larvae to rearrange 6000-8000 larvae of 2 cm long larvae or 4000-6000 larvae of 3-5 cm long larvae per acre on sunny mornings and evenings. The specifications for shrimps stocked in the same pond need to be neat and consistent. At the same time, about 50 grams of flowers, 300-400 white storks, and 200 squid can be stocked in pond water.
Three, carefully feeding
Within 3 days after seedling, minced small fish and minced meat were put in. Within 3 days, small trash fish, minced meat or compound feed was put in within 1 month, and when the shrimp was 6-7 cm long, it could be fed in full. Crushed snails, coriander, and appropriate amounts of vegetable feed such as wheat, bran, corn, cakes, etc., or compound feeds. The amount of daily feeding is based on feeding, eating, and no residual baits. Generally, the medium and small lobsters are fed at 15%-20% of the body weight, and the adult prawn is fed at 5%-10% of the body weight. The food condition of the shrimp is adjusted. Feed 2 times a day, once in the morning and in the 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 facilitate its use. Feeding.
IV. Water Quality Management
The lobster grows fast, the metabolism is strong, and the oxygen consumption is large. Therefore, the water quality of the shrimp pond should be kept fresh, and the water should be filled 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 at 35 cm deep Above, when the weather is overheating, it is necessary to properly deepen the pool water in order to stabilize the pool water temperature. Waterproofing is subject to industrial pollution, pesticide pollution and chemical pollution.
When the water is low in dissolved oxygen, water quality is aged, or thunderstorms are sweltering in hot weather, even in cloudy weather, reduce the amount of feeding or stop feeding, and observe the 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.
Fifth, prevent diseases
Diligently inspect, diligently inspect the ponds, and pay attention to the lobster's feeding, activities, growth, and clam shells, so that necessary technical measures can be taken in time. 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 creatures in the pool, such as water mice, water snakes, water birds, 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.
Six, timely fishing
General feeding 2 months or so, when the lobster weight of 50 grams or more, can be caught on the market, lobster caught using cages, cages, fences and other methods to catch large stay small.
