Can fish and turtles be raised together?
Turtles breathe with their lungs, instead of competing with fish for oxygen. On the contrary, the frequent up-and-down movements of turtles accelerate the dissolution of air oxygen into the water, promote the convection between the upper and lower layers of the pool water, prevent the supersaturated oxygen generated by photosynthesis of phytoplankton on the surface of the water from escaping into the air, and make up for the lack of dissolved oxygen in the deep water layer.
At the same time, turtles foraging at the bottom of the pond can accelerate the decomposition of organic matter at the bottom of the pond and reduce its oxygen consumption. Therefore, mixed culture of soft-shelled turtles can increase dissolved oxygen in water and reduce or avoid the danger of dead fish in flooded ponds.

Precautions:
1. Ponds with quiet environment, windless sunshine and convenient irrigation and drainage should be selected for aquaculture. If the turtle farm is autotrophic, five kinds of ponds should be built, namely, new school, kindergarten school, kindergarten school, 3-year-old school and adult school.
2. The soil in the pond is preferably clay or loam. If there is no sand at the bottom of the pond, mix some sand. At the edge of the culture pond, a drying platform and a feeding platform should be built to provide a place for turtles to dry their backs and eat. Asbestos tiles and bricks should be used to build an escape wall with a height of 1m around the aquaculture pond.
3. The optimum growth temperature of soft-shelled turtle is 30℃-32℃, and the food intake of soft-shelled turtle is directly proportional to the temperature, but the maximum temperature should not exceed 32℃, and the temperature should be kept as stable as possible.
