Don't forget the "five stables" when raising turtles.
Stability is the key to improve the survival rate of Trionyx sinensis in greenhouse.
1. Temperature is stable. As we all know, judging from the development speed of turtle culture in recent years, the most fundamental measure is to adopt the method of heating to cancel the hibernation period of turtles and achieve constant temperature growth all the year round, so as to achieve the goal of 12 months, 10 months, or even two years and three periods of rapid listing.
The turtle grows faster at 30℃-3 1℃ than at 28℃-29℃, but the fluctuating temperature between 27℃-32℃ is not as good as the stable temperature between 28℃-29℃. In the statistics of 45 ponds in an aquaculture company in Jingshan, the author found that the mortality rate was obviously different with different temperature difference. Therefore, it is best if the conditions remain stable at 30℃-3 1℃. If the conditions are not enough, it is best to keep it stable at 28℃-29℃. Of course, its growth rate is definitely slower, but its survival rate can be guaranteed.
2. The water quality is stable. The author visited hundreds of turtle farms in Hubei and found that black and green water can raise turtles well, and turtles need stable water quality more than fresh water. In the farms we see, black water, green water, brown water, muddy water at the bottom of mud and fresh water can raise turtles well. The key lies in the word "stability". Of course, "stability" is one of the key conditions, not all, and the environment that is unfavorable to the growth of turtles, such as long-term serious water pollution, is another matter. Green water is recognized as the best water area for turtle culture, but in the greenhouse without light, brown water can also show the degree of fat, vitality, tenderness and coolness of the water. These are two commonly used watercolors. As long as it is relatively stable, it is good water for raising turtles. In black water, some harmful microorganisms can also be inhibited. After adapting to the stable black water, the soft-shelled turtle eats vigorously and grows rapidly. The cultured soft-shelled turtle has good fatness, bright body surface, strong physique, strong resistance and low incidence.
3. Feed stability Soft-shelled turtle needs stable feed quality and flavor. Once it gets used to a certain feed, it can't be changed at will. If it changes at will, it will eat less or not. At the same time, there are three requirements for feed feeding: timing, quantification and fixed point. This will not only help to establish a stable conditioned reflex, ensure adequate nutrition, but also avoid unnecessary stress. Of course, stability is relative. According to the different growth stages of soft-shelled turtle, the required nutrients and palatability are different, so appropriate feed adjustment should be made in the growth stages of young soft-shelled turtle, young soft-shelled turtle, adult soft-shelled turtle and parent soft-shelled turtle.
4. The environment is stable except the water environment, and the instability of many external environments will affect soft-shelled turtles. For example, the weather changes, rainy weather and strong wind in the greenhouse will obviously affect its feeding, and for example, the Chinese soft-shelled turtle originally raised in the dark environment will be suddenly exposed to outdoor strong light, and its feeding will also be affected; For example, when the feeding table is unstable, or when feeding is changed from underwater to underwater, it will also affect the normal feeding of turtles; Another example is the sudden loud noise in a quiet and stable environment, especially the sudden shaking of shadows, including the appearance of personnel, which will also affect the feeding of turtles. Often this will not only affect the growth, but more importantly, it will produce stress, reduce immunity and disease resistance, and affect the survival rate of turtles.
5. Management is stable. Feeding management is a daily work, and it is the work of direct contact with turtles every day, and it needs stability. The frequency, time and way of feeding should be stable, the inspection of the patrol pool should be stable, and even the record of feeding management should be stable, and it should be remembered well every day.
