First, the benefits of the introduction of turtle seedlings in autumn and winter because the turtle seedlings from another environment into a new environment has a period of adaptation process, its cycle is 1-2 months, the turtle is often in a new environment, afraid of panic, predatory ability decreased. However, with adaptation over a period of time, it slowly adapts. The turtle is a variable-temperature animal. After entering autumn and winter, the turtle gradually grows slowly as the temperature gradually decreases. The advantage of autumn and winter introduction is to seize the moment when the turtle grows slowly, that is, to introduce the seedlings into the new environment. After the spring begins, the temperature rises and the turtle immediately enters the growth state. It does not need to adapt to the new environment. Under normal circumstances, The turtle seedlings introduced in autumn and winter are 1 to 2 months earlier than the spring turtle seedlings introduced in spring. Second, the key to success 1. Variety of quality selection of the right or wrong, a direct impact on economic efficiency. There are 25 species of freshwater turtles in China. Before the introduction, it is necessary to conduct a survey on the turtle market to confirm which type of turtle can be profitable, and then introduce it according to its own conditions. When introducing seedlings, they should go to farms or related specialized units with good reputation and good after-sales service. In recent years, due to aquaculture landslides, some of them have turned to raise turtles. As far as the country is concerned, most of the turtle farms only raise turtle species such as turtles, and most species of freshwater turtles have not yet been cultivated. The turtle seedlings are divided into hatchlings and hatchlings. It is advisable to introduce seedlings with 200 g of juvenile fish. The selection of turtle seedlings can be observed in terms of mental state, appearance, etc., the appearance is not injured, the claws are complete, and the responsive turtle is considered healthy. 2, the choice of aquaculture breeding mode according to their own conditions, it is best to local conditions. (1) Greenhouse rearing: Build a rearing pond, introduce turtle seedlings, control the water temperature at about 25°C (the suitable growth temperature of the turtle), and raise the turtle into a commercial turtle in a short period of time. Characteristics are: short growth cycle, quick, but large investment, under normal circumstances, the market is not easy to accept warming turtles, the price is lower than the average breeding, so it is not advisable to promote. However, this method can be used to breed turtles and is beneficial to the growth of hatchlings. (2) Polyculture of fish tortoises: The existing ponds are used to make slight modifications. New food chains are formed based on differences in living habits among animals and fish and turtles are set in ponds. Its characteristics: full use of ponds, improve feeding efficiency, low cost, not limited by the season, the risk is small. (3) Paddy field rearing: The paddy field has been slightly reconstructed and excavated into a “tian†type ditch. “Semi-ecological farming†has been implemented. Its features are: strong resource advantages, fisheries, and agricultural complementarity. It is worth advocating. 3, feeding technology (1) the density of the direct impact on the turtle's growth rate and survival rate. The high stocking density restricts the growth of the turtle and can easily cause the disease; on the contrary, the growth is suitable and the incidence is low. In general, young turtles (below 250 g) stock no more than 10 animals per square meter. (2) Feed. Turtle's growth rate, physical fitness, and resistance, the bait plays a leading role. Feeding feeds that lack certain nutrients can often lead to malnutrition and cause diseases. Because turtles need different nutrients and quantities in different stages of growth. (3) water temperature, turtles are temperature-changing animals, most turtles suitable for the growth temperature of 25 °C -30 °C. (4) Disease prevention and treatment. Turtle prevalence is difficult to detect only with external symptoms. Once the turtle has been found to be unresponsive to stuttering, symptoms such as limb weakness have become severe. Therefore, the principle of prevention must be the principle.
