1. water temperature control. The water temperature of 2℃-3℃ is the best temperature range for soft-shelled turtle growth. When the water temperature is higher than 2℃, soft-shelled turtle begins to eat, and the food intake increases with the increase of water temperature. When the water temperature is lower than the optimum temperature, the feed conversion rate will decrease; When the water temperature is higher than the optimal temperature, the feed conversion rate will also decrease due to the increase of activity, so the water temperature should be kept in the optimal temperature range, and too high or too low will cause feed waste.

2. Feed feeding. Underwater feeding is suitable for the feeding habits of soft-shelled turtles, which can speed up the feeding speed of soft-shelled turtles. Feeding with soft pellet feed saves more feed than feeding with block feed. The feeding of soft-shelled turtle is greatly influenced by the change of environmental factors. When the temperature and water temperature change and the medicine is used, the feeding amount should be adjusted considering the influence on soft-shelled turtle. Generally, underwater feeding should be controlled within 3 minutes. When the soft-shelled turtle eats too much, it grows too fast, which easily leads to the increase or overload of the physiological load of the soft-shelled turtle, which causes the damage of the internal organs of the soft-shelled turtle and induces visceral diseases.

3. Feed selection. Feed cost accounts for about 4% of the breeding cost, and the feeding method and the quality of the selected feed determine the success or failure of breeding cost control. Through the final benefit analysis, comparing the prices of high-quality feed and inferior feed with the comprehensive breeding cost, we can get out of the misunderstanding of choosing feed only by looking at the price.

4. Water quality control. Soft-shelled turtle is naturally fond of cleanliness and afraid of dirt. Good water environment is an important condition for the stable growth of soft-shelled turtle, and the quality control of water quality determines the success or failure of aquaculture. The main purpose of water oxygenation is to reduce the content of harmful gases and harmful organic matter in water, and to ensure the smooth flow of oxygenation facilities. However, it is necessary to choose to aerate the turtle in a fixed period of time, so that the turtle can form a habit and reduce the disturbance of oxygenation to the turtle.

5. Sewage discharge and water exchange. Regular sewage discharge is an effective means to control water quality, and water exchange is the most direct way to adjust water quality. When changing water, the amount of water exchange should be determined according to the water quality.
