1, water temperature control. The water temperature of 20℃-30℃ is the best temperature range for turtle growth. When the water temperature is higher than 20℃, the 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 optimum temperature, the feed conversion rate will also decrease due to the increase of activity, so the water temperature should be kept within the optimum temperature range, and too high or too low will cause feed waste.

2. Feed feeding. Feeding underwater is suitable for the feeding habits of soft-shelled turtles and 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, the influence on soft-shelled turtle should be considered and the feeding amount should be adjusted. Generally, underwater feeding should be controlled within 30 minutes. The turtle eats too much and grows too fast, which will easily lead to the increase or overload of the turtle's physiological load, damage the turtle's internal organs and induce visceral diseases.

3. Feed selection. The feed cost accounts for about 40% 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. Turtle is naturally clean 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 substances in water and ensure the smooth flow of oxygenation facilities. However, it is necessary to choose to aerate the soft-shelled turtle in a fixed period of time, so that the soft-shelled turtle can form a habit and reduce the interference of oxygenation on the soft-shelled turtle.

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