Introduction of turtle seedlings and culture methods in autumn

Because the turtle seedlings from one environment to another new environment has a period of adaptation, its cycle is 1 month to 2 months, then gradually normal, and the tortoise is a temperature-changing animal, after entering the autumn, with the gradual drop of temperature, the tortoise also grows slowly. The advantage of autumn introduction is to seize the opportunity of slow growth of the tortoise and let it adapt to the new environment. After the beginning of spring, when the temperature rises, the tortoise immediately enters the growth state, and there is no need to adapt to the new environment. In general, the seedlings introduced in autumn enter the growth period 1-2 months earlier than those introduced in spring.

Variety and quality

Whether the selection of varieties is correct or not directly affects the economic benefits. There are 25 species of freshwater turtles in China. Before introduction, it is necessary to investigate the tortoise market to determine which type of tortoise can make a profit, and then introduce it appropriately according to its own conditions. When introducing seedlings, you should go to a breeding farm with good reputation and good after-sales service or relevant professional units. In recent years, due to the decline in culture, some turtle farms have turned to @ # @ 238 turtles. As far as the country is concerned, most turtle farms only raise a few species of turtles, such as turtles, and most species of freshwater turtles have not yet been artificially cultured. Turtle seedlings are divided into juvenile turtles and young turtles. Mr. Jiang Zhanglin, director of the Longtou Pavilion Amphibian and Reptile Research Institute in Haining City, Zhejiang Province, suggested that it is appropriate for introduction households to raise about 200 grams of young turtles. The selection of turtle seedlings can be observed from the aspects of mental state and appearance. Turtles with no injuries on the body surface, complete claws and responsive tortoises are regarded as healthy.

Culture mode

The choice of breeding method depends on your own conditions, and it is best to adjust measures to local conditions.

The breeding pond was built in the greenhouse, the turtle seedlings were introduced, the water temperature was controlled at about 25 ℃ (the suitable growth temperature for turtles), and the turtles were raised into commercial turtles in a short period of time. The characteristics are: short growth cycle, quick results, but large investment, in general, the market is not easy to accept heating growth of turtles, the price is slightly lower than ordinary breeding, so it is not suitable to advocate. However, this method can be used to breed turtles and is beneficial to the growth of young turtles.

The mixed culture of fish and turtles made use of the existing ponds and slightly modified to form a new food chain according to the differences in the living habits of animals. Its characteristics: make full use of the pond, improve feeding efficiency, low cost, not limited by the season, less risk.

Rice field raising slightly reformed the rice field and excavated it into a "field" shaped ditch, carrying out "semi-ecological breeding", which is characterized by strong resource advantages and complementary fisheries and agriculture, which is worth advocating.

Feeding technique

The release density directly affects the growth rate and survival rate of turtles. The high feeding density restricts the growth of turtles and is easy to cause turtle disease; on the contrary, the growth is suitable and the incidence rate is low. Generally speaking, there are no more than 10 young turtles per square meter (less than 250 grams).

The growth rate, physique, resistance and diet of feed turtles play a leading role. If fed with feed that lacks certain nutrients, it will often lead to malnutrition and disease of turtles. Because turtles have different requirements for nutrients and quantity at different growth stages.

Water temperature turtles are variable temperature animals, and the suitable temperature for most turtles to grow is 25 ℃ ~ 30 ℃.

The disease prevention and treatment of turtles are difficult to detect only by appearance symptoms. Once the symptoms such as lack of food, slow response and weakness of limbs are found, the disease is already serious. Therefore, it must be based on the principle of prevention.
