Snapping turtles are native to North America and Central America, also known as small snapping turtles. In recent years, they have been successfully introduced into artificial breeding in China. They are known for their strong and fleshy meat. They are also called turtles and are rare species in turtles. It is characterized by high meat yield, rich nutrition, fast growth, and high economic value. Its meat yield ranks first in the turtle class. Snapping turtle meat is delicate, crispy, delicious, and has no odor. The nourishing effect is very obvious. Turtle has a swelling effect, turtle blood, glans have a certain medicinal value.
First, living habits Snapping Turtles can live in a water temperature of 3°C to 45°C, are most active at 20°C to 30°C, and grow fastest at 28°C to 31°C, hibernate below 15°C, and do not under ice in -5°C water. Will be frozen to death, more than 1 °C can safely over the winter, snapping turtles enjoy a quiet habitat, eating more mixed, like eating small animals and aquatic animals in the water, also on the shore to eat dead, live animals, fresh leaves and flowers and fruits. Artificially fed feeds include fresh fish, shrimp, snails, clams, insects, cockroaches, cocoons, maggots, yellow mealworms, various animal and poultry internal organs and waste, and extruded feeds.
2. The selection depth of the rearing pond is 1m to 1.5m. The area of ​​the pond shape is not limited. On the side of the pond, 10% to 20% of the ground should be used as the spawning ground. The masonry should be laid in the pool to prevent the turtle from hitting. Holes and spawning grounds were also smoothed with grout and put 40 cm thick sand. The spawning ground should be sloped at 45 degrees and covered with wood or foam to prevent it from scratching the belly of the turtle. A layer of sand and clay should be placed at the bottom of the pool. On the land of Chizhou, another 1m to 1.5m high anti-escape fence will be constructed. Small breeders can use pots and cover with nylon nets. For example, turtles should be built with larger pools. The spawning grounds should be placed on a pool 2 cm to 3 cm above the surface of the water. The new cement pool should be disinfected with 15ppm to 20ppm bleaching powder, and soaked in a thousandth superphosphate solution for one to two days and then put into the turtle.
Third, feeding and management
1. Graded stocking ponds can be reared in groups of 1 turtle (1 males and 2 females) or middle turtles 3 groups or hatchlings 5 ​​to 10 groups or hatchlings 10 to 20 groups per square meter. Can not be mixed, so as not to affect the growth of small turtles.
2. Fixed-point, regular-time, quantitative-feeding feeding in the early spring and early winter every day at noon; late spring and late autumn is the peak season of food intake, feeding twice a day, 90% feeding at 9:00, and feeding 60% in the evening, feeding It should be fixed at a place. The foodstuffs to be eaten in 150 minutes will be eaten. It will be less to eat the next time. The food should be cut to a large size. The small hatchling should be fed nutritious chopped feed, and the spoilage feed should not be used. The feed is mainly based on animal feed. It can be used with some vegetable, fruit and vegetable feeds, or it can be fed with turtle feed.
3. Change the water regularly, disinfect the pool with large area, change the water 1 time in 20 days to 50 days, change the water in the small pond for 2 days to 3 days or 6 days to 7 days, and maintain the transparency in 10 cm to 20 cm. Depending on the situation in the winter, try to change the water as little as possible, but the pot should be changed in time. Pool water is generally disinfected with 10ppm bleach for 20 days to 30 days, which can prevent the occurrence of turtles. In summer, the pool water must be kept 80 centimeters. Above the pool should be shaded by 1/5 or more. The pond should be fed with duckweed and trees should be planted. If necessary, new water should be injected to cool the water so that the water temperature does not exceed 45°C.
4. Breeding and Hatching Wild Snapping Turtles begin to spawn in the fifth year, while hatchlings began to lay eggs in the third year or 2 kg or more. April-May and September-October natural mating, May-August for the spawning period, female turtles spawn during the day, the annual egg production 30 to 120. 2 batches to 3 batches of eggs were laid, 11 to 50 pieces each. The incubator is 80 cm high, 50 cm wide and 80 cm long. Several leak holes are drilled at the bottom of the box, 5 cm thick sand is placed, and 5 cm of fine sand is placed. The eggs are placed on the sand (animals with white dots are facing upwards) , then cover 5 cm fine sand, and then cover with rodents, snakes. The coarse sand used was first scalded with boiling water. Eggs are inspected once a day. If the surface is dry on the surface of the sand, it should be moisturized and moisturized. It is advisable to hold the sand in groups and loosen it. A hatchling can be hatched from 65 days to 75 days under natural temperature. The hatching rate is 93% to 96%. If the temperature is 30°C and the relative humidity is 80% to 90%, hatchlings can hatch from 50 days to 60 days. The hatching rate can reach 98%. After the hatchlings are hatched, they are allowed to move in the incubator for several hours until the umbilical cord falls off. That is, they are transferred into a 200 ppm potassium permanganate solution and sterilized for 5 minutes, and then put in clear water for rearing.
Fourth, disease control As long as the strict disinfection of small turtles and pool water, generally have little disease, occasional minor illnesses, the right medicine, you can treat. Traumatic inflammation and colds can be treated with cephalosporin mix; gastroenteritis is fed with norfloxacin; dyspepsia is treated with multi-enzyme solution or yeast tablets; hydromycosis is dipped with “hydromycotic†solution for 15 minutes or with saline solution. Immersion disease turtle can be.
