Crocodile turtles live in rivers, lakes, ponds and swamps and feed on fish, waterfowl, snails, shrimps and water snakes. Crocodile turtles have outstanding predation ability. Whenever it finds a small animal drinking water by the water, it will suddenly swing its tail, stun its prey and drag it into the water to enjoy it slowly. Crocodile turtles rarely move on land. Only in the breeding season will females climb to the shore and choose a suitable place to lay their eggs. Can produce 30- 120 eggs at a time. After about 100 days, the young turtles can hatch. The growth rate of young turtles is amazing, and they can grow to 2 kilograms a year. Three years later, the baby turtle began to mature sexually. Crocodile turtles were killed by humans, and now they are very rare in the wild, ranking sixth among the top ten endangered and rare wild animals in the world published by the World Wildlife Federation report. 1. Feeding mode 1. Feeding: feeding: feeding under the condition of natural real snapping turtles, once a day in early spring and early winter, and feeding at noon with high temperature. Spring to late autumn is the feeding season for soft-shelled turtles, which are fed twice a day, 9 ~ 10 and 4 ~ 5 pm, accounting for 40% of the total feeding in the morning and 60% in the afternoon. Feed should be placed on the slope or in the corner of the pond, or a board can be placed under the water surface of the slope for feeding. Once you feed in a fixed place, don't change it frequently, and put the feed at 90 ~ 65438. There are many kinds of feed, and compound feed is also acceptable. But it should be noted that the big ones should be cut into small pieces, the hard ones should be softened with water, and they can be eaten raw and cooked. Young turtles should be fed more nutritious feed and cut into small pieces as much as possible to facilitate digestion. Don't feed spoiled feed. You can also properly mix some plant feeds, such as melons and fruits. 2. Environment: (1) stocking L group (1 male and female) or 3 groups of medium turtles or 5 groups to 10 group of young turtles or 10 group to 20 groups of young turtles in different grades per square meter, which will not affect the growth of young turtles. (2) Fixed-point, fixed-time and quantitative feeding: every noon in early spring and early winter 1 time. Late spring to late autumn is the peak period of feeding, with 40% in the morning and 60% in the evening, twice a day. Feeding should be fixed in one place, and the food you throw should be eaten within 1.5 hours. If you can't finish it, you can throw less next time and cut the big one. The feed is mainly animal feed, which can be properly matched with some plant flowers and fruit and vegetable feed, and can also be fed with turtle feed. (3) Change the water regularly in ponds with large disinfection area, 20 days, 20d~ 50d days 1 time, and small ponds with 2 to 3 days or 6 to 7 days 1 time. The transparency is kept at 10ppm ~ 2 cm. In winter, change the water as little as possible according to the situation, but change the water in time for pots and pans. Generally, the pool water is 20 days, 20 days 20d~ 30d days 1 time. (4) In summer, the pool water must be kept 80cm, and the pool water should be shaded above 1/5. Some duckweeds should be raised in the pool, trees should be planted around it, and fresh water should be injected to cool down if necessary, so that the water temperature does not exceed 45℃. 3. In the third year of breeding and hatching, wild snapping turtles began to lay eggs, and artificially bred snapping turtles began to lay eggs at the age of 18 months or above 1kg. April-May and 9- 10 naturally mate, and May-August is the peak of spawning. Female turtles lay eggs at night, 30 ~ 120 eggs a year, divided into 3 ~ 4 batches, with 8 ~ 50 eggs in each batch. Incubation method: The incubator is 20cm high, 50cm wide and 70cm long. Drill a few leaking holes in the bottom of the incubator, put 5cm thick sand and 5cm fine sand, put the eggs on the sand (the animals with white spots face up), cover with 5cm fine sand, and then cover with rodents and snakes. Used coarse sand and fine sand are disinfected by scalding with boiling water. Check the eggs once a day. If the surface sand is dry, it should be moistened with water, and it is advisable to hold the sand in your hand and let it develop naturally. At the natural temperature of 65d~75d, the hatchability of young turtles can reach 93% ~ 96%. If the temperature is 30℃ and the relative humidity is 80% ~ 90%, the hatching rate can reach 98% after 50 days to 60 days. After the young turtles hatch, let them move in the incubator for 5 minutes and last for several hours. When umbilical cords fall off, transfer them to 200ppm potassium permanganate solution for disinfection for 5 minutes. 4. Two-season intensive care in Xia Dong. The temperature is high in summer. In some areas, the outdoor temperature exceeds 40℃, the surface temperature exceeds 60℃, and the water surface temperature exceeds 45℃. At this time, it is necessary to deepen the water in the pool, never less than 30 cm, shade more than one-fifth in the open-air pool, or stock duckweed plants in the pool to cool down. You can also plant some fruit trees by the pool. Try to keep the water temperature below 43℃. Crocodile turtle has strong adaptability, belongs to a temperature-changing animal, can tolerate high and low temperatures, and can survive in water temperature of 5℃ ~ 43℃, but it is most active at 23℃ ~ 38℃ and grows fastest at 28℃ ~ 3L℃. Hibernation activity is less below 15℃, and all hibernate below 13℃. According to the experiment, I hope you are satisfied.
