Native American snake turtles originated in the United States. In 1996, China began to introduce them. At present, there are a small number of farmers breeding in East China and South China. The feeding environment of American snake turtles is simple. It is adaptable to temperature, cold in winter, and can hibernate naturally; it is not afraid of heat in summer, and it has strong disease resistance and fast growth speed. The American snake turtle is a turtle species with high meat content. Its meat is delicious and has high nutritional value. Because of its high ornamental value and medicinal value, raising American snake turtles is a good way for farmers, farmers, and fishermen and laid-off workers to get rid of poverty and become rich and well off and re-employment. Now we introduce the living habits, food habits, breeding and artificial breeding technologies of American snake turtles for your reference.
First, living habits and food in the wild, the American snake turtle is a water turtle, living in fresh water. Such as lakes, rivers, marshes and pools, can also live in saline water with low salt content. Such as the bay, estuary bay, like in the water sediment, shrubs, weeds. When the American snake turtle floats in the water, it is not easy to be found with its protective color on the back of the turtle floating like a piece of rotten wood in the water. It often sticks its nose out of the water, and its head does not fully extend. The American Snake Turtle likes to be in the water during the day, lying on the wood or stones, and sometimes floating on the water. Sometimes the four legs are pointing upwards, the dorsal armor is facing downwards, the head is exposed upwards and the night begins to crawl. American snake turtles are not afraid of the cold and do not fear the heat. Ambient temperature above 18°C, it can feed normally, 20°C-33°C is the best activity and feeding temperature, less than 34°C, low temperature in the bottom and sediment, 15°C-17°C. Activities, hibernation below 15°C, hibernation below 10°C.
American snake turtles are omnivorous animals. Wild fruits, stems and leaves, shrimp, small fish, small crabs, clams, snails, clams, otters, small frogs, clams, freshwater parasites, etc. are all foods. Under artificial feeding conditions, pork, beef, eggs, livestock and poultry organs or leaves can also be eaten. Second, the breeding of American snake turtle female and male identification: adult male body is larger in size, with a longer and thicker tail, and the cloacal hole is located in the outer edge of the carapace; female turtle short and thin, cloacal hole in the back of a edge.
In the mating season of the United States, the male turtle often climbs to the back of the female turtle from April to September each year. At first, the female turtle crawled, and after the male fell off, he chased and climbed again, and so repeated until the female turtle stopped crawling. The male turtle has a hind leg and the front claw hooks the female turtle's dorsal armor. During the process of mating, the male head and neck are straight and shaken from side to side, sometimes the nostrils of the two turtles face each other. May-September is the spawning period every year, and June-July is the most prolific spawning period. In the wild, the female turtle climbs to the shore and looks for open land, usually about 200 meters from the water's edge. Eggs in artificial breeding are produced in the sandy soil near the pool. The caves dug by the turtles are small in the caverns and large in the bottom of the cave. There is a certain degree of curvature downwards. The cave is 10 cm to 15 cm deep. There are 11-83 eggs per litter, usually from 20-30 eggs, and large turtles spawn more eggs. Eggs are white, spherical, slightly rough appearance, egg weight 7 grams -15 grams. Natural hatching takes 55 days - 125 days. Manual hatching of hatchlings usually takes about 50 days.
Third, artificial breeding technology
1. Selection of hatchlings: The adaptability and resistance to disease of American snake turtles are very strong. When buying, look mainly at appearance and constitution. Eyes are gods, head and neck flexible, neat appearance, no fester, five injuries, full claws, physical fitness, limbs hypertrophy, can support themselves when crawling.
2. Daily feeding and management: American snake turtles live in water. Therefore, food should be put into water or placed in water when feeding. Under artificial rearing conditions, the American snake turtles have lower requirements for bait and can generally feed poultry viscera and cheap oysters. The specific daily operations should follow the principle of "three adaptations," namely, "timely, appropriate, and appropriate." Feeding time is from 9am to 10am and from 3pm to 5pm. When the water temperature is 17°C, feed is stopped. When the water temperature is 20°C-33°C, it is the best feeding temperature of the turtle. The amount of turtle feeding should be two small and middle large. That is, less feeding in early spring and late autumn, and more feeding in spring, autumn, and summer. In the feeding season, change the water frequently.
3. Construction of greenhouses for greenhouse cultivation: Artificial breeding of American snake turtles with heat preservation is very effective. If the conditions permit, the large-area warm greenhouse cultivation, the growth rate is indeed alarming. According to the trial of a leading animal farm in Yuanhua Town, Haining City, Zhejiang Province, the fastest annual growth rate is 1250 grams for each snake turtle. The specific approach of this field is: In order to make the turtle grow normally under simulated natural conditions, the indoor breeding needs to increase the light, and each shelf feeds light with 40 watts of sunlight per day for more than 12 hours.
Every year from November to April of the following year, the iron frame for raising turtles is sealed with plastic foam plates on the upper and lower sides, and then the plastic film surrounds and fixes the periphery to form a warm shed. The internal heating wire is used for heating (other heating methods are also available). An automatic temperature controller keeps the internal temperature above 25°C so that the turtle can feed normally.
After feeding for 9 months to 10 months by the above method, the turtle body can reach 800 grams to 1200 grams and can be put on the market for sale. If the group is raised for 12 months, it can grow to more than 1500 grams, and the largest can reach 2,000 grams or more. If it is rented out after April, turtles can be kept in outdoor ponds for several days and fed with natural feeds. The appearance and inner meat quality can be similar to the wild natural American snake turtles, which is more welcomed by food lovers.
