1. Build the pool. The soft-shelled turtle is quiet and afraid of the sound, Xiyang afraid of the wind, Xi Jie afraid of dirty. To build a pond to choose a quiet environment, sheltered from the sun, drainage and irrigation convenient pond as a breeding base. For self-cultivation, self-breeding, and self-supporting breeding farms, it is necessary to consider the construction of five types of ponds in the new ponds, the young fish ponds, the young fish ponds, the third instar pond, and the Chengchi pond. There is no sandy soil at the bottom of the pond. Sandy soil is to be added. Ponds and baits are built on the sides of the pond and the pool. The turtles should be used for drying and eating. Four weeks should be built to prevent escape, brickwork and asbestos. Can be inserted vertically, about 1 meter high.
2. Choose seedlings. At present, the source of the soft-shelled turtle is mainly two aspects: one is factory-based nursery and professional households are mass-produced; the other is wild turtles of different sizes on the market. However, no matter what kind of soft-shelled turtle, it must be raised for 15 days when entering the pond. For scarred small soft-shelled turtles and adult fish (some of which are caught with hooks), they have to be raised separately and wait for the injury before they are thrown into ponds according to specifications. For those who are slow to respond and difficult to move, they should be treated after the disease is cured. In general, 667 square meters cast 2 to 3 instar juveniles 100 to 150 kilograms, up to a maximum of 200 kilograms.
3. Scientific feeding. At present, the bait for feeding turtles in the world is mainly fishmeal, but the price is expensive, and some of the quality is unqualified, and turtles are susceptible to enteritis after eating. The scientific method is to use natural feeds, such as the collection of discarded livestock and poultry, scraps and scraps from nearby hotels and canteens; in natural waters, snails, clams, small fish, shrimps, and various leeches; use natural or sporadic Land, breeding mud loach, snails; using gully, pond slope breeding clams; attracting fly breeding; breeding insects. In soft-shelled turtle feed, add a small amount of plant feed, such as bran, corn flour, bean dregs, and a small amount of melons and trace elements, and process and mix and feed.
4. Adjust water quality. Although soft-shelled turtles breathe in the lungs, they live in the water most of the time. The environment for growth is water. Therefore, water quality is good and it is still very important for the growth of soft-shelled turtles. Keep the water depth 0.3 to 0.4 meters, change the water once every 3 days, change the amount of water by 1/3 each time, the water color is in the green state as well, can conceal each other, reduce the chance of mutual injury, can also put a small amount of water in the water Water lilies, water hyacinths and other green plants to improve water quality. Into a pool, change the water every 4 days, each time a quarter of the amount of water, keep the water fresh and cool, dissolved oxygen, adequate fat.
5. Control disease. The common diseases of turtle are the following:
1 hydromycosis. Visible to the naked eye in the turtle's limbs, neck, tail, etc., water mold, slow growth, prevention and control methods are: disease armor alone, daily 1/15000 malachite green solution dip 2 to 3 minutes for 7 days, the symptoms can be Completely eliminated.
2 neck disease. The neck of the turtle was obviously swollen, with mouth and nose bleeding, and the plastron was anemic. The prevention and control method is: use "rich chlorine" to disinfect the pool water, and then use the "healthy" treatment.
3 Red neck disease. Turtle neck swelling, abdominal congestion, red spots on the body, the disease is acute infectious diseases, such as the prevention and treatment is not timely, will cause a large number of dead turtles. The prevention method is: regularly disinfect with lime water to keep the water in the pool clean. Add 1/2000 “sucking healthy†to the feed, or feed each kilogram of soft-shelled turtle with chloramphenicol and 0.2 grams of oxytetracycline. 10 days for a course of treatment; the initial incidence of soft-shelled turtle, per kilogram of penicillin injection, 200,000 international units of streptomycin in the abdomen of soft-shelled turtles, 1 or 2 times.
4 intestinal inflammation. Turtle excrement has odor, poor digestion and slow action. The prevention method is: In the feed, add 1% garlic juice, onion, 7 days for a course of treatment.
5 Hemorrhagic disease. Blood spots occurred in the plastron of the soft-shelled turtle, bleeding in the intestine and respiratory organs, and hemorrhagic lesions in the kidneys and liver. The prevention and control methods are: rapid isolation of disease A, and treatment with “healthyâ€, sulfonamide or antibiotics.
6 white spot disease. The turtle's limbs and skirts appear spotted, and then gradually expand into white spots, necrosis of the epidermis, especially the young armor is highly susceptible to the disease. Control methods are: rubbing the diseased area with 1% malachite green ointment. Be careful not to hurt the turtle body. The disease develops slowly in fertilizers and develops rapidly in lean water, thus maintaining the pool water. Inhibit the spread of mold, and use chlorine-rich water to completely disinfect the pool water.
7 Turnip disease. Turtles, tails, limbs, and skirts appear to have erosions of the epidermis. In severe cases, the epidermis rots, the claws fall off, and the neck muscles and bones are exposed. The prevention and control method is: In addition to the pool water all use "chlorinated", "sputum health" for disinfection, the disease will be quickly isolated, daily with 100 microliter / litre sulfa drug solution for 2 to 5 minutes, 1 day twice , 7 days for a course of treatment, generally healed.
8 cold disease. The temperature of the water injected into the new water is too low. Causes the turtle to be uncomfortable at first and causes dizzy symptoms. The prevention and control method is: Each injection of new water should maintain the same temperature as the pool water. If you inject water into the river in the summer, it is difficult to keep up with the pool water temperature, and only increase the surface flow of water injection, prompting the river water to gradually warm up and narrow the temperature difference.
