Feeding environment of small snapping turtles
1, graded and divided into pools. L breeding turtles (1 male and 2 females) or 3 middle turtles or 5 to 10 young turtles or 10 to 20 young turtles can be kept in different pools per square meter, so as not to affect the growth of young turtles.
2. Feed 1 time at noon in early spring and early winter, and feed twice a day from late spring to late autumn, with 40% at 9: 00 a.m. and 60% at night. Feeding should be fixed in one place, and the food you throw should be eaten within 1.5 hours. If you can't finish eating, you can throw less and eat more next time. 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. The water in the pool with large disinfection area should be changed regularly, with part of the water changed for 20 days 20d~ 50d days 1 time, and part of the water in the small pool should be changed for 2 days to 3 days or 6 days to 7 days 1 time. Transparency should be kept at 65,438+00 cm to 2 cm. Change the water as little as possible according to the situation in winter, but change the water in the basin in time. Generally, the pool water is changed once every 20 days for 20d~ 30d days. 4. In summer, the water in the swimming pool must be 80cm, and the swimming pool should be shaded 1/5 or more. Some duckweeds should be raised in the pool and trees should be planted around it. If necessary, fresh water should be injected to cool down so that the water temperature does not exceed 45℃.
5. 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. Young turtles can hatch at natural temperature for 65d~ 75d days, and the hatching rate is 93% ~ 96%. If the temperature is 30℃ and the relative humidity is 80% ~ 90%, after 50 days? The hatched larvae can hatch within 60 days, and the hatching rate is 98%. After hatching, let it move in the incubator for several hours. When the umbilical cord falls off, put it in 200ppm potassium permanganate solution for disinfection for 5 minutes, and then put it in clean water for feeding.
Special care in Xia Dong in two seasons: the temperature is high in summer, the outdoor temperature in some areas exceeds 40℃, the surface temperature exceeds 60℃, and the water temperature exceeds 45℃. At this time, it is necessary to deepen the pool water, not less than 30 cm, cover the open-air pool by more than one fifth, or stock duckweed plants in the pool to cool down, or plant some fruit trees beside 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,
Method for raising small snapping turtle
Pay attention to the water, tap water can only be used after 2-3 days.
Don't cross the crocodile turtle's back. Get some sunshine every day and you will be healthy.
Feed it once a day, small fish and shrimp, internal organs, etc.
Biological characteristics of small snapping turtle
Crocodile turtle looks strange. At first glance, it looks like a crocodile. Its snout is prominent, its head sticks out and it can't shrink into its shell. Its upper and lower jaws are slightly pointed, its eyes are short, and its tail is thick and long, with fleshy protrusions on it, like the tail of a crocodile. The carapace is short and wide, the adults are mostly brown (the larvae are black), and there are three blurred edges on the back. Adult's abdominal armour is light yellow or white (larvae are black), with small abdomen and fat limbs, which can't be retracted into the shell. Webbed toes's long claws.
Crocodile turtles are amphibious turtles that live in shallow water or swamps. I like lying in mud, bushes and weeds. Sex is gentle, will not attack each other, will not hurt people. When caught, it will emit a smell similar to musk. Omnivorous, eating wild fruits, plant stems and leaves, small crabs, shrimps, maggots, earthworms, snails, frogs and algae. Artificial can feed all kinds of animal viscera, vegetable leaves, apples and so on. , and can be fed with artificial compound feed.
Crocodile turtles can live normally in the water temperature of 3℃-45℃. Crocodiles at -5℃ in nature will not freeze to death when hibernating. Hunger tolerance, no sudden infectious diseases found. Crocodile turtles begin to mate and lay eggs when their weight is above1000g. A female turtle lays eggs 1.50 a year, divided into 3-4 batches. The egg is spherical and white, with a diameter of 23-33mm and a weight of 7.15g. The incubation period is about 40 days.
