The living habits of turtles;
This kind of turtle likes to grow in the crevices of streams in rocky mountainous areas, so it has the reputation of "mountain treasure". The optimum water temperature for the growth of Trionyx sinensis is 25 ~ 32℃. When the water temperature is 37 ~ 38℃, the soft-shelled turtle is very uncomfortable and easy to die of heat.
When the water temperature is 12℃, the activity of soft-shelled turtles decreases, and they hibernate in the mud instead of foraging, but they don't hibernate continuously like ordinary soft-shelled turtles. As long as the temperature rises above 20℃, it will drill out of the water and go out for food.
Trionyx sinensis is an omnivorous animal, which mainly feeds on animals. In nature, it is eat small fish, shrimp, insects, worms and so on. In the case of artificial farming, people like to feed snails, snails, mussels, fish, animal offal, earthworms and fly maggots. Turtles generally eat a lot at night, and the feeding amount is generally 5%-8% of their body weight.
Population status of Trionyx sinensis;
The number of Eriocheir sinensis is decreasing year by year, which belongs to extremely endangered species. The main reasons are mass capture and water pollution. Turtles are precious economic animals. In the past, the consumption of soft-shelled turtles in some high-end hotels and restaurants was mainly soft-shelled turtles, and the demand was large.
In Guangdong and Guangxi, as economic resources, in the past, in addition to supplying the domestic market demand, soft-shelled turtles were exported to Hong Kong in large quantities every year, with the number measured by tons.
Reproductive status of Trionyx sinensis;
Each female turtle lays eggs 1-2 times a year, a few lay eggs 3 times, each time 5- 15, and large individuals can sometimes lay more than 20 eggs. Turtle protein color, round, diameter 15-20mm, weight 10- 13g. The fertilized egg has a bright white area at the animal pole, with a diameter of 4-7 mm. If there is no white area after 3-5 days, it means that the egg is not fertilized.
Generally speaking, turtles mate and breed in spring and summer. During the breeding period, females dig holes in sunny beaches or mud to lay eggs. They lay eggs twice and several times a year, and each time they lay more than 3-20 eggs. After laying eggs, they cover the eggs with sand or soil and hatch with the help of the heat of sunlight. Oval, the incubation period is about 30 days or more. After a natural incubation of 1 month, it became a larva.
When the baby turtle comes out of its shell, it will crawl into the water by itself.
Oviposition, may ~10, and June is the peak. At night, female turtles dig holes in sunny and humid coastal beaches or mud to lay eggs. Hole depth11~18cm. The spawning ground is no more than 2 meters away from the water surface. Laying eggs twice a year, several times and three times, each time laying eggs 3- 18.
