Causes and preventive methods of death of soft-shelled turtle after overwintering

Soft-shelled turtle is a culture project with high economic benefits. in the period of market shortage, soft-shelled turtle can bring high economic benefits to farmers and has a good breeding prospect. Death often occurs in soft-shelled turtle hibernation, and the number of deaths is still relatively large, this phenomenon is called overwintering death, and some people call it overwintering disease, so what is the cause of this phenomenon? How to prevent it? Let's take a look.

First, symptoms

Overwintering death is a death phenomenon of soft-shelled turtle after hibernation. The causes of its attack are different and the symptoms are also different. Some soft-shelled turtles float on the surface after death, some sink in the bottom of the water or in the sand, and some die when they climb ashore, and the causes of their death are various, including internal injuries, trauma, weakness, disease and parasites.

Second, the reason

1. Malnutrition: Egypt and Egypt, which came out of their shells in autumn, will enter the overwintering period without adequate nutrition after a short period of feeding, when their physique, cold resistance and disease resistance are weak. it's easy to cause their death.

2. Improper management: from June to August every year, it is the peak breeding season for soft-shelled turtles, and it is also the time for the largest food intake. in order to increase the fecundity, some farmers often attach importance to the hatching and feeding of juvenile soft-shelled turtles, while neglecting the cultivation of parent soft-shelled turtles, resulting in the death of parent soft-shelled turtles after overwintering.

3. Physical weakness: not only young soft-shelled turtles die after overwintering, but female soft-shelled turtles also do so. in 1-2 months before overwintering, female soft-shelled turtles lay the best batch of eggs, consuming a lot of physical strength and nutrition, so their physique is extremely weak. but the temperature that followed drops, prepare for the winter, often enter the overwintering period before recovery, easy to die.

4. injury or freezing: soft-shelled turtles die when they are physically injured or frozen before or before overwintering, and often float on the surface or sink to the bottom of the water to rot after overwintering. If they do not die during the overwintering, they will die very quickly after overwintering.

5, the water quality is poor: there is no holiday water quality management when overwintering, and the water is not changed in time when overwintering, which will lead to more and more harmful substances in the water, thus poisoning the soft-shelled turtle to death.

III. Preventive methods

The main results are as follows: 1. Before the soft-shelled turtle overwintering, it is necessary to strengthen the feeding management, feed concentrate and animal bait, especially to feed the animal viscera, maintain and accumulate nutrition, so as to make it have sufficient nutrition consumption during overwintering. Before overwintering, the water temperature is lower and the soft-shelled turtle has less food intake, so it is necessary to strengthen the feeding when the water temperature is 30 degrees. At this time, the soft-shelled turtle has a large food intake and high feeding utilization rate.

2. When the water temperature begins to drop to 25 degrees after autumn, artificial measures should be taken to raise the water temperature to 30 degrees and keep it warm for one month, so as to prolong the growth period of soft-shelled turtles, so that the soft-shelled turtles can accumulate enough nutrients to survive the winter, especially young soft-shelled turtles and females after spawning.

3. Harassment, capture and transportation are prohibited when overwintering, so as to avoid scraping, frostbite and death of soft-shelled turtles caused by these operations.

The above are the causes and preventive measures of soft-shelled turtle death after overwintering. I hope I can help you. If you want to know more about soft-shelled turtle culture, please follow us.
