Through scientific feeding and management, the reproduction rate and growth rate can be effectively improved. Chinese soft-shelled turtle mainly feeds on fish, shrimp and mollusks, and also eats plant food such as aquatic plants and cereals. Chinese soft-shelled turtle generally mates in autumn, and female turtles begin to lay eggs in early May of the following year. They can lay eggs several times a year, with about 10-30 eggs each time. After an incubation period of 40 to 70 days, the young turtles hatch. In addition, during the artificial breeding process, sufficient water sources and land shore conditions are required to ensure their healthy growth.
