A baby turtle pool After 6 months of incubation, hatchlings enter hibernation when the water temperature drops below 15°C. The wintering period of snapping turtles in Hainan starts from the end of December and ends around mid-February of the following year.

A rectangular concrete pool is used. The pool is 6m long, 3m wide and north-south. The wall of the pool is 0.4m-1.0m high. The top of the wall is inward. The corner of the pool is round and the bottom slope is 100:10. The deepest water level in the south is 40cm-50cm. Drain holes are provided at the bottom of the pool. The land area in the north is between 3 m2 and 6 m2, with shallow water at the food station. The water injection uses a submersible pump of 1.5 and absorbs water from the pond. Cultivation pool set shade nets, water hyacinth stocking. On average, 10 to 12 young turtles are stocked per square metre.
Second, daily management
1. Daily management in summer and autumn
(1) Feeding
Adhere to the "four principles" principle. In the summer high temperature season, feeding twice a day, feeding time is 7:00-7:30 and 18:00-18:30 is appropriate. After the fall of the water temperature in the fall, the hatchling's food intake decreased and the feeding was changed to one. The time is appropriate for 17:30-18:OO. The feed station is located 100m to 20cm offshore and 1cm to 2cm away from the water surface. Snapping Tortoises Young tortoises like to feed on the same ingredients and tastes. If a sudden change in feed composition affects their food intake, a gradual transition should be taken when changing feed formulations. The feed we used was tilapia net meat, which was smashed with a minced meat machine. We added turtle feed, and kneaded it into a feed cake of about 25 g. The daily feeding amount was adjusted at any time according to water quality, weather, and feeding conditions. The daily feeding amount of the turtle is about 3.5g-10g, and it is necessary to stop feeding in the case of strong winds and heavy rain, and the feeding amount should be within 1-2 hours. Usually measured once every 10 days.
(2) Water quality regulation
Snapping turtle breeding does not require high water quality, and fresh water is preferred. Water should be rich in plankton-bearing rivers, lakes, and ponds. Water hyacinths should be stocked in the water to provide hiding places for hatchlings and provide shade and adjustment. Water quality effect. For juvenile tortoises in the summer and autumn, the amount of residual feces is large, change the water every afternoon.
(3) Disease prevention and control insists on prevention, and regularly adds antibiotics, vitamins and trace elements to food. Common diseases are perforation and red neck disease.
Perforation occurred in early June in the Hainan area, with a high incidence from late July to October. Symptoms are the initial stage of disease, the turtle floating on the surface of the water, irritable, slow movement, loss of appetite, and finally leave the body of water and dry in the dry place, slow response to human disturbance. Turtles, abdomen, and skirts appear white spots, severe cases cause sores, and sores can be seen deep into the body. Treatment: 1 fed fresh compound feed supplemented with oxytetracycline baits. Dosage is 0.2g per kilogram of body weight, halved on the 2nd to 6th days, and then fed for another course of treatment every 10 days. 2 Remove the sores and apply the wound with gentian violet. The severe one can be applied with erythromycin ointment once a day for one week.
Red neck disease can occur in the spring, summer and autumn in Hainan. Symptoms are red swelling of the neck, head and neck can not shrink in the human shell. Slow action, reflecting dullness, congestion of the oral mucosa. Severe condition of the mouth, nose bleeding, blindness, body edema. Treatment: 1 If the disease is mild and you are still able to ingest food, add appropriate antibiotics or sulfonamides to the feed. Dosage is 0.2g per kilogram of body weight, halved in the first 2-6 days, 6 days for a course of treatment, and even fed 2-3 courses. 2 Place the diseased turtle in the isolation tank and spill it with erythromycin at a concentration of 2 ppm.
2. Daily management during wintering
(1) Prepare for wintering: Snapping turtles should deposit about 30cm thick clean river sand (disinfected and exposed) on the floor of the hatchery pond before winter and deepen the level of the turtle pool as much as possible. Prepare the straw curtain to cover the top of the wintering pool when cooling down.
(2) Intensive cultivation before winter: In last winter, the minimum temperature in Hainan dropped to 9°C, and the maximum temperature sometimes rose to above 20°C. The young turtles got into dormant sand at low temperatures, and drilled Shawo activities when the temperature increased. Some young turtles even wintered in the deep waters of the pool throughout the winter. Due to the increased temperature during the hibernation, the young turtles often move around during hibernation and non-hibernation. The snapping turtles consume a lot of energy. After wintering, young turtles generally need to reduce their weight by about 10% to 20%. Therefore, the fortification of young turtles before winter is very important. Feed high-protein, high-fat feeds, and extend the feeding time as much as possible so that the body can accumulate enough energy. In addition, antibiotics are added to the feed to increase their resistance to disease so as to facilitate the normal wintering of snapping turtles.
(3) Water quality regulation: Change the water frequently to ensure that the young turtles that live in the water for winter have a good wintering environment and reduce the occurrence of diseases; pay attention to changing the water should choose sunny weather, the water temperature temperature difference does not exceed 2 °C.
(4) Prevention of predatory organisms: During the winter period, rats were found to have entered the overwintering pool to injure hatchlings. In order to prevent the invasion of rats, birds, and other predator organisms, the use of waste mesh nets to make the wintering pool size of the damage prevention net covered The pool surface is tied around the perimeter so that it ensures light, breathability, and plays a protective role.
Third, the growth situation
The speed of growth of young snapping turtles is directly related to food consumption and bait conversion rate. Within a certain range, the snapping rate of bait snapping changes with increasing temperature. Tests have shown that the bait coefficient is 5 when the water temperature is between 29°C and 32°C; the bait coefficient is 9.2 when the water temperature is between 23°C and 25°C; The bait coefficient is 10 at 20°C-23°C. When the water temperature is between 30°C and 31°C, the hatchling grows quickly and the average daily weight gain can reach 2.3g. When the water body temperature drops to 22°C-23°C, the average daily weight gain of the hatchling is only 0.21g. It is very important for snapping turtles to eat and grow.
