Money turtle ecological rapid culture technology

The money turtle, the scientific name of the three-lined shell turtle, is one of the precious species of turtles and it is promising to develop artificial breeding.
The money turtle is delicious and nutritious, and it is a traditional Chinese herbal medicine. It has the functions of nourishing yin and yang, benefiting the liver and lungs, dehumidifying and detoxifying, sublimating the Yang fever, reducing swelling and cancer, and stopping bleeding.
The money turtle is unique in shape, beautiful in appearance, and of high ornamental value. It has been an auspicious pet since ancient times and has been hailed as a treasure of “town house”.
1.Characteristic characteristics The appearance of the money turtle has four basic characteristics: first, the back is brownish or grayish black, there are 3 black vertical lines that are obviously raised, and the middle one is the most obvious and the longest, so it is called three lines. Shell turtles and "chuan" characters back turtle; second, the top of the head with yellow, gray or blue diamond logo, smooth without scales; third, plastron for the transverse, connected by the ligaments, the turtle shell can be completely closed, so it The plate turtle was cut off; fourth, the outer skin of the turtle's lower end was golden orange, so it was also called the Phnom Penh turtle.
Money turtles like to live together, eating mixed, mainly prey on small fish shrimp, oysters, snails, shellfish, all kinds of insects, snakes, rats, fruits, etc., especially love to eat oysters. Its diet includes animal organs, raw and cooked bones, sweet potatoes, potatoes, pumpkins, vegetables, fruits and so on. The money turtle lives in a quiet environment, clean water, and sunny waters. Often digging holes in the creek to make a nest, rest in the hole during the day, go out to eat in the evening. Low temperature resistance, 12 °C into hibernation, 21 °C began to activity, 25 ~ 32 °C optimum growth, growth water temperature is 20 ~ 32 °C, 29 ~ 31 °C water temperature activity is most active. More than 1000 grams of body weight mature, 5 to 9 months for the spawning period, spawning 2 times a year, spawning 2 to 7 pieces each time.
2. The rearing pool is constructed according to the biological characteristics of the cash tortoise. The turtle pond is used to facilitate both water and land movement. It is also conducive to feeding and resting on land. In this condition, the monthly weight gain can be achieved. 50 to 75 grams.
The size of aquaculture ponds should be 10 to 20 square meters. During construction, consideration should be given to warming during wintering. Generally, the depth of the pool should be about 1 meter, the depth of water should be 0.5 to 0.7 meters, and the water surface and land ratio should be 2:, and the land should be 0.2 to above the water surface. 0.5 meters into a 25-degree slope to facilitate turtles crawling up and down; land turtle nests and spawning grounds, spawning grounds with 0.3 to 0.4 meters deep mixed sand (4:6 soil to sand ratio), built in the food table Water and land connections. A 2.5-meter-high wall should be built around the pool, and the wall base should be buried 0.6-0.8 meters to prevent the turtle from escaping. Some melons, beans and vines can be planted near the pool. Mulberry trees, buckwheat trees and pastures can be planted beside the pool. Sangzi and pods are good foods for turtles. A small amount of small fish, snails, water lettuce and duckweed can be stocked in the pool. Per square meter of breeding ponds can be stocked 15 to 25 young turtles, or turtles 5 to 10; or pro-tortoise 2 to 3, pro-toads ratio of 2:1.
3, feeding and management
(1) Quantitative feeding at regular intervals: 1 to 2 times per day, fresh and clean food, first animal feed, and 1 hour before feeding fruit and other bait. When formulating food, it can be combined with a small amount of vitamins and inorganic salts, animal foods account for 70%, vegetable foods account for 30%, and the remaining foodstuffs should be promptly cleaned up.
(2) The transparency of the changing pool water should be maintained at 0.3 to 0.5 meters in time to keep the water fresh. When water quality deteriorates, clean fresh water should be replaced in time. Dirty water at the bottom of the pool should be pumped out (or released), and then equal amount of fresh water should be injected. The general water exchange rate is 1/3 to 1/2. If you need to replace all new water, you should wash the pool first, then add new water. Well water and tap water cannot be added directly.
(3) Regularly disinfect turtle ponds to keep them clean and clean. In spring and autumn, they should be disinfected once a month and once a week in summer. Disinfectant can be used at a concentration of 3 mg/L bleach, or 10% lime water, or 2 to 5% potassium permanganate solution.
4. Warming Rearing and warming feeding means that during the wintering of the turtle, in order to keep the money turtles growing fast, 7 to 20 grams of hatchlings will be bred into 500-plus-meter commercial turtles within one year. Greenhouses are generally built at the leeward sunny side, should be east-west, the south wall is 1.6 to 2 meters high, built in the wintering pond wall, the north wall is 2 to 2.5 meters high, built at a meter away from the turtle pond, the east and west walls each open a window To facilitate ventilation. The greenhouse roof truss can be welded with triangle iron. The roof is glazed with glass tiles. The plastic film is pulled under the tile to keep warm. The roof is covered with straw at night, and the straw curtain is opened on sunny days. To maintain the water temperature at 28 ~ 31 °C, the indoor air temperature is preferably higher than the water temperature of 2 ~ 3 °C, if the heater heating, close to the turtle pool should be set underground smoke exhaust pipe to facilitate insulation, and pay attention to regulating temperature. In the late winter, it is necessary to open windows for ventilation.
