Before the turtles are stocked, the ponds must be sterilized. The newly-created soft-shelled turtle pond uses 100-150 kilograms of lime per acre. It is turned into a splash of lime slurry, and it is given after 7 days. In addition to disinfection of the old pond to clear the pond, but also check the anti-escape facilities, found that the damage repair. In the summer, large-leaf melons can be planted on the shore of the pond or scaffolding can be used to shade the turtle.
1, control the temperature
Turtle seedlings are moved from outdoor greenhouses into outdoor ponds. The most important thing is to control the temperature of the water. If the temperature difference is too large and the weather changes, it is not appropriate to move to outdoor stocking. After the temperature has continued to stabilize for several days, stocking should be conducted when the temperature difference does not exceed 2°C.
2, pick the seedlings
Choose turtles that are robust, disease-free, harm-free, weighing 50 grams or more, and body length of 7 cm or more, and have the same size and uniformity as the pond. The size and size of the soft-shelled turtle shall be divided into open and raised, and the physique is weak. The individual may be intensively fed in a greenhouse for a period of time. After the body is restored, it is put into a suitable pond for rearing.
3, stocking density
The stocking of young turtles should be determined based on the technical conditions of the ponds, water sources, feeds, feeding and management, and the expected product specifications. The usual stocking density is 7,000 to 9,000 per mu. When stocking, take a bath with vitamin B12 or vitamin C (100-200) mg/L for 30 minutes, then add 100,000 to 150,000 IU penicillin per kilogram of water, and dip for 2 hours before entering the pond. .
4, with fish species
Each mu of soft-shelled turtle ponds can be used with 50 to 100 grams of white bream species ranging from 200 to 300 and 100 gram or more of calyx and 50 to be polycultured. This will not only increase the utilization rate of water bodies, but also adjust the water quality, and achieve dual-use of fish. Harvest. However, during the stocking period, feeding should be strengthened to keep the water fresh.
