Hibernation time of soft-shelled turtle The soft-shelled turtle is a kind of temperature-changing animal, which is very sensitive to the temperature change of the external environment, and the temperature directly affects its activity ability and feeding intensity. Under natural conditions, the suitable temperature range for feeding and growth of soft-shelled turtle is 24℃ ~ 33℃, and the optimum temperature range is 27℃ ~ 365,438+0℃. When the water temperature drops to 22℃, the turtle's appetite and activity gradually weaken, and when the water temperature drops to about 65438 08℃, it stops eating completely. When the water temperature continues to drop, turtles will dive into the mud to hibernate, thus reducing energy consumption and achieving self-sustaining.
Second, the importance of the management of the Chinese soft-shelled turtle during the wintering period. It is very important to manage the overwintering period of soft-shelled turtle to improve the survival rate, commodity rate and economic benefit. This is because during hibernation, turtles maintain their lives by consuming energy accumulated in their bodies. In this way, after a long wintering period, the physique of soft-shelled turtles will generally drop significantly. If the management is not good in the early and middle stages of overwintering, turtles will die in large numbers. Due to the decline of disease resistance and stress resistance, it will also directly affect the annual output. Therefore, it is particularly important to strengthen production management, restore and strengthen the physique of soft-shelled turtle, improve the ability of disease resistance and stress resistance, and prevent diseases in this period.
Three management skills 1, temperature management
The winter temperature in most parts of China is low, but the temperature suitable for turtle growth is generally 25 to 30 degrees, the lowest temperature should not be lower than 10 degrees, and the highest temperature should not be higher than 32 degrees. However, in winter, the temperature is about 5 to 8 degrees, which is a great challenge to the survival of turtles. Therefore, only artificial methods can be used to maintain the appropriate temperature in the farm, such as injecting spring water, building windbreak walls, building greenhouses and so on.
2. Water quality management
Soft-shelled turtle has stricter requirements on water quality in winter than at other times. One of the reasons is that the temperature in winter is low, the activity of water is low, and ammonia nitrogen is easy to produce, which has a great influence on the water quality, and ammonia nitrogen is a great threat to the growth of soft-shelled turtle, which will cause gastrointestinal discomfort and systemic rot. You can't change water frequently in winter, which will affect the temperature of the swimming pool. First of all, we can plant some plants in the water, which can purify the water quality to some extent. Secondly, the pH value of water can be controlled, and a proper amount of quicklime is sprinkled, which is more conducive to the growth of soft-shelled turtles.
