Under the condition of artificial feeding, fish, pork, beef and poultry offal can be fed. Plant food can be fed to apples and vegetable leaves.
Chelydra Serpentina, also known as small crocodile turtle and meat turtle, is native to North and Central America. Crocodile turtle looks strange, looks like a crocodile at first glance, keeps the characteristics of primitive turtle, is an aquatic turtle, and lives in fresh water or brackish water.
Crocodile turtles mainly eat animal feed and plant feed; Crocodile turtles have strong vitality and disease resistance, and grow rapidly, with an annual weight gain of about 800g. This turtle has the highest meat yield in the world, with a meat yield of 85%-90%. Its meat is tender, delicious and highly nutritious. The feeding environment of snapping turtles is simple and adaptable, which has high edible, medicinal and ornamental values.
Crocodile turtle is a rare new breed introduced from the United States to China in recent years. Crocodile turtles are native to North America and Central America, and are famous for their strong and fleshy bodies, so they are also called meat turtles, which are rare among amphibians in fresh water. Crocodile turtle has the characteristics of high meat yield, rich nutrition, fast growth, high economic benefit, etc. The meat yield is 85-89%, which is 1.5 times of that of ordinary turtles. It is a kind of turtle with the highest meat yield in the world, and its meat tastes delicious, even thousands of dollars per kilogram of golden turtle is not as good as it, and it is crispy and has no odor than the fish meat of nail. Crocodile turtle meat is a high-grade natural nutritious food with high protein, high amino acid, low fat, low cholesterol and low calorie. It can dredge meridians, help yang, tonify yin and blood, and benefit vital energy. It is a good product for people with chronic illness, postpartum tonic, male and female weakness, anemia, insomnia and brain decline. Tortoise shell has the function of detumescence and cancer treatment. Turtle blood and glans also have medicinal value. The back shell is a natural handicraft, and multiple turtle shells can be synthesized into unique exquisite handicrafts. The economic value of snapping turtles can be compared with that of ostriches. In the United States, ostrich meat is $0/00 per kilogram, while snapping turtle meat can reach $0/50-180 per kilogram.
Features: Crocodile turtle looks like a crocodile, which is a combination of turtle and crocodile, so it is called Crocodile turtle. Its head is thick and can't be completely retracted into the human shell, its neck is short and thick, its collar and back are covered with brown spines, its eyes are small, its mouth and jaws are small, its snout is pointed, its tail is pointed and long, with edges on both sides, and its edges are covered with fleshy spines. Two-thirds of the front of its tail back has a scaly ridge with a serrated mouth, its back shell is thin, its epithelium is mainly brown, and occasionally it is brown, and its back has three stripes.
Distribution: North America and Central America along the Mississippi River Basin.
Living habits: Crocodile turtles grow on the banks of rivers and forests, like to live in a quiet environment, like tidal temperature, and are amphibians. Crocodile turtles can live in the water temperature of 3~45℃, and they are most active at 20~30℃, and grow fastest at 28~3 1℃. They hibernate below 15℃, and don't freeze to death under the ice layer in water at-5℃. Above 1℃, they can spend the winter safely.
Feeding habits: the feeding habits are miscellaneous, and they like to eat small animals and aquatic plants in the water, and also eat dead and live animals, fresh and tender grass leaves and flowers and fruits on the shore. Feeds artificially raised include: fresh small fish and shrimp, snails, mussels, insects, earthworms, silkworm chrysalis, fly maggots, Tenebrio molitor, offal and scraps of various livestock and poultry, puffed feed, etc. Its food intake changes with the change of environmental temperature, generally accounting for 3-5% of its weight, and it is also fed with compound feed after being trained.
Market dynamics: Crocodile turtles are on the verge of extinction due to over-capture. In recent years, it has been successfully introduced into China for artificial feeding. It is famous for its strong and fleshy body, so it is also called meat turtle. It is a rare and best among turtles and has the characteristics of high meat yield, rich nutrition, fast growth and high economic value. Its meat yield ranks first among turtles, and its meat is delicate, crisp and delicious, and has no peculiar smell. Its nourishing function is very obvious, and it can dredge meridians, nourish yin and blood, and benefit essence and qi. It has obvious effects on deficiency of essence and blood, fatigue and fatigue, chronic paralysis and weakness, and cough due to deficiency after a long illness. It is also especially suitable for postpartum tonic, anemia, insomnia and mental decline. The tortoise plastron has the function of reducing swelling and is suitable for yin deficiency and blood deficiency caused by cancer. The glans penis also has certain medicinal value. In addition, it is beautiful in shape and has high ornamental value.
Feeding instructions:
Feeding: feeding under natural conditions, once a day in early spring and early winter, and feeding at noon when the temperature is high. The period from spring to late autumn is the peak season for turtles to eat, and feeding should be done twice a day at 9~ 10 am and 4~5 pm. Feed 40% of the total feed in the morning and 60% in the afternoon. Feed can be placed at the corner of the slope or pond, or a board can be placed under the water on the slope for feeding. Once feeding is done in a fixed place, it should not be changed frequently, and the feed should be put at 90 ~/kl.
There are many kinds of feed, and compound feed is also acceptable. However, it should be noted that the big ones should be cut into small pieces, and the hard ones should be softened with water, both raw and cooked. Young turtles should be fed more nutritious feed and cut into small pieces as much as possible to facilitate digestion. Do not feed spoiled feed. Can also be properly matched with some plant feed, such as melons and fruits.
Environment: 1, group L (1 male and 2 females), group 3, group 5 ~ 10 or group 0 ~20, which can be stocked per square meter, shall be kept in different pools according to different sizes, and shall not be mixed, so as not to affect the growth of young turtles.
2, fixed-point, fixed-time, quantitative feeding early spring and early winter at noon every day 1 time, late spring to late autumn is the feeding season, feeding twice a day, feeding 40% at 9: 00 a.m. and feeding 60% in the evening, feeding should be fixed in one place, and the food dropped should be eaten within 1.5 hours, and less feeding can be done next time. The feed is mainly animal feed, which can be properly matched with some plant flower and fruit vegetable feed, or can be fed with turtle feed.
3. Regularly change the water for the pool with a large disinfection area, and partially change the water 1 time for 20d~ 50d, and partially change the water 1 time for the small pool for 2d~ 3d or 6d~7d. The transparency should be kept at10cm ~ 2cm. In winter, the water should be changed as little as possible according to the situation, but the water in the pots should be changed in time, and the pool water is generally 20d.
4. In summer, the water in the pool must be 80cm, and the pool should be shaded above 1/5. Some duckweeds should be raised in the pool, and trees should be planted around it. When necessary, fresh water should be injected to cool down, so that the water temperature does not exceed 45℃.
5. Breeding and incubating wild snapping turtles began to lay eggs in the third year, while artificially bred snapping turtles began to lay eggs when they were 18 months old or grew to more than 1kg. April-May and September-0/October naturally mate, and May-August is the peak period for spawning. The female turtle lays eggs at night, with 30~ 120 eggs per year, and lays eggs in 3~ 4 batches, with 8-50 eggs in each batch. Incubation method: The incubator is 20cm high, 50cm wide and 70cm long. Drill several leaking holes at the bottom of the incubator, put 5cm coarse sand, 5cm fine sand, put the eggs on the sand (animals with white spots are facing upwards), cover the fine sand with 5cm, and then cover it with rodents and snakes. The used coarse sand and fine sand are first scalded and disinfected with boiling water. Check the eggs once a day. If the surface sand surface is dry, it should be drenched with water to moisturize, and it is advisable to hold the sand in hand and let it go. The hatchability of young turtles can be 93%~96% at natural temperature of 65d~ 75d. If the temperature is 30℃ and the relative humidity is 80% ~90%, the hatchability can be 98% after 50d…60d. After the young turtles are hatched, let them move 5min the incubator for several hours. When the umbilical cord falls off, they will be transferred to 200ppm potassium permanganate solution for disinfection for 5 minutes.
Special care in summer and winter: the temperature is high in summer, and 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 pool water, never to be less than 30 cm, shade the open-air pool by more than one fifth, or stock duckweed plants in the pool to cool down, or plant several fruit trees beside the pool. Try to keep the water temperature below 43℃.
The snapping turtle has strong adaptability, belongs to a temperature-changing animal, is resistant to high temperature and low temperature, and can survive in a water temperature of 5℃~ 43℃, but it is most active in 23℃~ 38℃, and its growth speed is the fastest in 28℃~ 3l℃. It hibernates below 15℃, with little activity, and all hibernates below 13℃.

The tortoise plastron has the function of reducing swelling and is suitable for yin deficiency and blood deficiency caused by cancer. The glans penis also has certain medicinal value. In addition, it is beautiful in shape and has high ornamental value.
Feeding instructions:
The crocodile turtle has a strong vitality. It is relatively simple to raise by hand, and it is neither afraid of cold nor heat. It is safe and sound at -6℃, and the water temperature at 42℃ can grow normally. It has low requirements for raising conditions and environment. It can be raised in tanks, barrels, pots, etc., and it is best to build ponds. Bricks and cement are used to build a pool with a depth of 60cm, and the pool area can be determined according to the number of breeding. The newly-built cement pool must be soaked in clean water for two weeks before it is reused except for its alkalinity. About 20-30cm sediment is laid on the bottom of the pond; The fence should be 60cm above the water surface, and a bank slope with a width of 1 m can be paved with fine sand between the fence and the water surface for crocodile turtles to go ashore and lay eggs. Crocodile turtles have strong adaptability, high temperature and low temperature resistance, can survive in water temperature of 3-45℃, and will not freeze to death under the ice in water at -5℃. They can be raised in water basins, water tanks and cement pools indoors and outdoors. Crocodile turtles can grow up to 5-1 2kg at most, generally to1kg for sale, and 0.4-1.2kg a year. For example, if they are raised in greenhouse, they will grow faster, which is beyond the reach of other turtles and soft-shelled turtles. Crocodile turtles have high reproductive rate, fast growth, high economic benefits and broad breeding prospects.
Feeding: feeding under natural conditions, once a day in early spring and early winter, and feeding at noon when the temperature is high. The period from spring to late autumn is the peak season for turtles to eat, and feeding should be done twice a day at 9~ 10 am and 4~5 pm.

However, it should be noted that the big ones should be cut into small pieces, and the hard ones should be softened with water, both raw and cooked. Young turtles should be fed more nutritious feed and cut into small pieces as much as possible to facilitate digestion. Do not feed spoiled feed. Can also be properly matched with some plant feed, such as melons and fruits.
Environment:
1, graded and divided into pools, each square meter can be stocked with L groups of breeding turtles (1 male and 2 females) or 3 groups of middle turtles or 5 groups of young turtles ~ 10 or young turtles 10 ~20 groups, and kept in different pools according to different sizes, so as not to affect the growth of young turtles.
2, fixed-point, fixed-time, quantitative feeding early spring and early winter at noon every day 1 time, late spring to late autumn is the feeding season, feeding twice a day, feeding 40% at 9: 00 a.m. and feeding 60% in the evening, feeding should be fixed in one place, and the food dropped should be eaten within 1.5 hours, and less feeding can be done next time. The feed is mainly animal feed, which can be properly matched with some plant flower and fruit vegetable feed, or can be fed with turtle feed.
3. Regularly change the water for the pool with a large disinfection area, and partially change the water 1 time for 20d~ 50d, and partially change the water 1 time for the small pool for 2d~ 3d or 6d~7d. The transparency should be kept at10cm ~ 2cm. In winter, the water should be changed as little as possible according to the situation, but the water in the pots should be changed in time, and the pool water is generally 20d. 4. In summer, the water in the pool must be kept 80cm, and the pool 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 when necessary, so that the water temperature does not exceed 45℃.
5. Breeding and incubating wild snapping turtles began to lay eggs in the third year, while artificially bred snapping turtles began to lay eggs when they were 18 months old or grew to more than 1kg. April-May and September-0/October naturally mate, and May-August is the peak period for spawning. The female turtle lays eggs at night, with 30~ 120 eggs per year, and lays eggs in 3~ 4 batches, with 8-50 eggs in each batch. Incubation method: The incubator is 20cm high, 50cm wide and 70cm long. Drill several leaking holes at the bottom of the incubator, put 5cm coarse sand, 5cm fine sand, put the eggs on the sand (animals with white spots are facing upwards), cover the fine sand with 5cm, and then cover it with rodents and snakes. The used coarse sand and fine sand are first scalded and disinfected with boiling water. Check the eggs once a day. If the surface sand surface is dry, it should be drenched with water to moisturize, and it is advisable to hold the sand in hand and let it go. The hatchability of young turtles can be 93%~96% at natural temperature of 65d~ 75d. If the temperature is 30℃ and the relative humidity is 80% ~90%, the hatchability can be 98% after 50d…60d. After the young turtles are hatched, let them move 5min the incubator for several hours. When the umbilical cord falls off, they will be transferred to 200ppm potassium permanganate solution for disinfection for 5 minutes.
Special care in summer and winter: the temperature is high in summer, and 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 pool water, never to be less than 30 cm, shade the open-air pool by more than one fifth, or stock duckweed plants in the pool to cool down, or plant several fruit trees beside the pool. Try to keep the water temperature below 43℃.
The snapping turtle has strong adaptability, belongs to a temperature-changing animal, is resistant to high temperature and low temperature, and can survive in a water temperature of 5℃~ 43℃, but it is most active in 23℃~ 38℃, and its growth speed is the fastest in 28℃~ 3l℃. It hibernates below 15℃, with little activity, and all hibernates below 13℃.
In addition, snapping turtles have high medicinal, edible and ornamental values, and artificial breeding has far-reaching significance for the protection and rational development and utilization of wild animals. Following the world ostrich fever and the domestic turtle, frog, shrimp and crab fever, it will become a new hot spot and rare new species of efficient special aquaculture. Large-scale farming has been started in foreign countries 1998, and the price per kilogram of crocodile turtle meat is 160 USD in the American market. International markets such as the United States and Canada have matured; However, there are only a few small-scale aquaculture in China at present, and the benefits of aquaculture are very considerable with the gradual improvement of domestic market demand. The opportunity is right in front of you, and the opportunity is fleeting.
Male and female identification:
The male has a large figure and a long tail, the length of which is 86% of that of the abdominal nail, and the cloaca is located outside the edge of the dorsal nail. The female, on the other hand, has a short tail, the length of which is less than 86% of the length of the abdominal nail, and the cloaca is located within the edge of the dorsal nail.
Reproductive habits:
Every year, mating occurs from April to September, and the spawning season is 5- 1 1 month, and June is the peak season. There are 1 1-83 eggs in each nest, usually 20-30 eggs. The eggs are white, spherical and slightly rough in appearance, with a diameter of 23-33mm and a weight of 7-15g. After hatching for 55- 125 days, the hatchlings are hatched in different environments, and the hatching days are also different. When the incubation temperature is above 30℃, the young turtle is female below 20℃, and when the incubation temperature is between 22℃ and 28℃, the young turtle is male. The young turtle weighs 9.5-12g, the carapace is 24-30mm long, the carapace is round and black, and there are protrusions on each shield.
