Construction scheme of soft-shelled turtle farm

The soft-shelled turtle is very sensitive to the change of external temperature, and its life rule is closely related to the change of external temperature. At 10-12 ℃, the soft-shelled turtle goes into hibernation, and when the water temperature rises to about 15 ℃ in spring, it gradually wakes up from hibernation and begins to feed. Above 20 ℃, male and female soft-shelled turtles mate and spawn. The optimum temperature range for feeding and growth of soft-shelled turtle is 2530 ℃, and it is also the best season for artificial culture. More than 33 ℃, looking for holes to "summer", artificial culture, because the soft-shelled turtle nature is aggressive, large and small soft-shelled turtle is not suitable for mixed culture, the phenomenon of bullying among groups is very common, when food is scarce, it will cannibalize the same kind.

Selection of soft-shelled turtle culture site

The living habits of soft-shelled turtle can be summarized as "three joys and three fears", that is, Xi Jing is afraid of shock, Xi Yang is afraid of the wind, Xi Jie is afraid of dirty. The soft-shelled turtle is sensitive to the sound of the surrounding environment. As long as there is a little movement around, the soft-shelled turtle can quickly dive into the underwater silt. In the natural environment, soft-shelled turtles like to inhabit clean rivers, lakes, reservoirs, ponds and other waters, and often lie on the sunny bank during the calm day to bask in the sun (commonly known as sun back), using ultraviolet rays in the sun to kill pathogenic bacteria on the body surface. promote the healing of injured body surface, raise body temperature by basking in the back, and promote food digestion.

1. Avoid the wind and the sun without noise. Soft-shelled turtle is lung breathing, need to intermittently float out of the water and breathe air, such as loud noise, soft-shelled turtle can not sunbathe because of timidity, long-term hiding in the underwater soil, soft-shelled turtle will adhere to moss and its bacteria, infected with diseases. At the same time, the noise stimulates the central nervous system of the soft-shelled turtle, which will cause the imbalance of excitation and inhibition in the cerebral cortex, disrupt the metabolic law, and affect the heart function, digestive function and reproductive function.

2. Good water quality and convenient irrigation and drainage. The water source of the soft-shelled turtle pond should not contain ammonia and polluted water. The water should be fresh, flowing and warm. In general, water from rivers, ponds, lakes and reservoirs can be used as a source of water for raising soft-shelled turtles. If the temperature is high in summer, new water can be replaced regularly in order to prevent water pollution. The ideal soft-shelled turtle farm should be able to fill in and drain the water.

3. Rich in bait. The supply of convenient soft-shelled turtle has strict requirements for bait, especially animal bait with high protein content. Therefore, the farm had better choose in the meat factory, restaurant attached. The bait room should be dedicated and should not be integrated with chemical fertilizers, pesticides and other rooms.

Construction of soft-shelled turtle farm

Soft-shelled turtles of different ages need different bait, and they need special water temperature and water quality. in addition, soft-shelled turtles are ferocious, competing for food and aggressive, so they must be raised in different levels. Build parent turtle pond, adult turtle pond, juvenile turtle pond, juvenile turtle pond. In addition, an isolation pool for diseased soft-shelled turtle should be established.

1. Parent turtle pond. The spawning of parent soft-shelled turtle needs to be stable and quiet, so the turtle pond should be built in a place with convenient irrigation and drainage, higher terrain, sufficient sunshine and quiet environment. Soft-shelled turtle pond area size according to local conditions, block north to south, sunny shelter from the wind, spawning site in the wall with sand pile 3-5, about 20 cm thick, sand pile size according to the number of stocking. Some weeds or tall leafy crops should grow near the spawning ground to provide a good amphibious environment for parent soft-shelled turtles to spawn. Conditional places can also be built around the spawning ground in the spawning room, an area of 5 square meters, 1.5 meters high, glass roof. A small hole is left on the side of the water surface of the spawning ground as an entrance and exit. The back wall of the spawning room opens a small door, and people are free to enter the room for management.

2. Adult turtle pond. Except for the spawning ground, the other facilities and principles of the adult turtle pond are the same as those of the parent turtle pond.

3. Juvenile turtle pond. After overwintering, the juvenile soft-shelled turtle enters the growth period of the young soft-shelled turtle, the juvenile soft-shelled turtle pond and the adult soft-shelled turtle pond are basically the same, and the area is slightly smaller than the adult turtle pond.

4. Get out of the turtle pond. The juvenile soft-shelled turtle just out of its shell has relatively high requirements for bait because its internal organs are not fully developed. if there is no suitable juvenile turtle pond and scientific management measures, it will cause juvenile soft-shelled turtle casualties during the overwintering period. There are two forms of juvenile soft-shelled turtle ponds: one is an indoor cement pond with an area of 10 square meters, a depth of 60 square meters, a water depth of 20 centimeters, a bottom sand layer thickness of 15 centimeters and a rest table area ratio of 1:6, which requires ventilation and light transmission. The other is an outdoor cement pool or earth pool, with an area of 50 to 80 square meters, a depth of 80 to 100 centimeters, a water depth of 40 to 60 centimeters, a bottom sand layer thickness of 20 to 30 centimeters, and a resting table area ratio of 1:10, requiring shelter from the wind in the sun.
