In the winter when feeding soft-shelled turtles, on the basis of ensuring safe wintering, if you can break the hibernation, you will have higher economic benefits.
1. Select the overwintering pond soft-shelled turtle as a variable-temperature animal. The water temperature drops below 15°C and stops feeding. After 10-12°C, it infiltrates into the sediment under water and hibernates. When the water temperature rises above 15°C in the next spring, it is eaten. Therefore, it is usually in November. He was hibernated until April of the following year. Ponds should be selected where the leewards are sunny, the water quality is non-pollution, the environment is peaceful, the irrigation and drainage are easy, and the management is convenient. There are more hot water and geothermal water. The bottom of the pool should be 30 cm thick.
Second, strengthen the feeding and feeding The main feed contains protein and fat feed, such as snail shellfish, animal offal, etc., so that it accumulates rich nutrition, in order to increase the fullness and supplement energy consumption, improve the survival rate of overwintering.
Third, warming against cold and preventing hypoxia on juvenile, into a soft-shelled turtle pond, conditions can be used to heat the boiler heating hot water (heat insulation material laying pool, the use of pipelines to transport hot water), or microwave heaters, mining Hot water, hot spring water warming. General farmers do not have the above conditions, and can use the method of soil, that is, cover the pool with transparent plastic film or take a plastic shed to warm the sun by warming. In addition, new water should be added to facilitate insulation and prevent hypoxia.
Fourth, break the hibernation and promote the growth of juveniles. The juvenile fish that hatched from June to September of that year can be raised outside for a period of time. The feed should be fine, fine and fresh. It should mainly feed small red worms, cockroaches, and cooked eggs to strengthen the body. After the cool autumn season, it can be transferred to overwintering greenhouse ponds and warmed by using simple boilers to break hibernation and feed it in appropriate amount to easily digestible soft foods. In this way, the survival rate from the original natural wintering can be increased from 10% to 95%.
Fifth, strengthen the patrol pool constantly check the treatment temperature, water level, water quality, dissolved oxygen, frozen snow and so on, and at the same time to prevent human and animal injuries, to ensure the safety of young and adult soft-shelled turtle overwintering and survival and growth of young turtles.
For the summer of low-priced acquisition of high prices for the spring sale of "temporary turtles," can also be used above the breeding method to increase the benefits of the coming year.
