After hatching, after the umbilical cord converges, it is disinfected with 10% physiological saline, and then put into a container with a water temperature of 25℃-30℃. Change the water three times a day, and feed the mixture of boiled eggs and boiled millet after three days. Feed chopped small fish, snails, mussels, animal offal and leftovers for about 50 days. After three months, it can be moved into the turtle pond for breeding.

In the juvenile stage, the control of water temperature is the key to directly affect the weight gain and survival rate of adult turtles. The optimum water temperature for the growth of snapping turtles is 30℃ ~ 3 1. If the water temperature is 18℃ ~ 20℃ for a long time, its growth rate will be greatly slowed down.

In case of severe weather such as heavy rain or sudden temperature change in the water changing or exposed turtle pond, appropriate measures should be taken to prevent the water temperature from changing more than 2℃.

Water quality regulation

1, change the water in time. The water depth of 20cm can be changed once a day, and the water depth of 30cm can be changed once every two days.

2. Lime disinfection. Crocodile turtles raised in ponds can be sprayed with quicklime once every 7 days to 10, and the concentration is 70× 10-6.

3. Spraying photosynthetic bacteria at the bottom can effectively improve water quality and reduce harmful substances. Every time the new pond is filled with water, photosynthetic bacteria are applied simultaneously:10×10-6 ~15×10-6.
