Soft-shelled turtle is also called water fish, group fish and foot fish, commonly known as tortoise. Soft-shelled turtle is rich in nutrition. It is not only delicious on people's table, but also a kind of medicinal material. Its nourishing effect is deeply loved by people. So, how to breed soft-shelled turtle? Let's take a look at turtle culture technology with Huinong.com Bian Xiao. Physiological characteristics of soft-shelled turtle culture: the optimum temperature of soft-shelled turtle is 28~30℃, and it begins to hibernate below 15℃, and grows slowly above 32℃. May to August is the breeding season. Farms must be equipped with parent spawning ponds, spawning grounds, juvenile ponds, small ponds and adult ponds. The sexual maturity age of Trionyx sinensis is 5-6 years old in North China, 4-5 years old in the Yangtze River valley and 3-4 years old in tropical South China. Turtles used for breeding are generally about 6 years old, and the ratio of male to female is 3: 1. The mature female turtle's tail is short and cannot naturally extend beyond the skirt, while the male turtle's tail is pointed and can extend beyond the skirt. Soft-shelled turtle culture technology: 1 The dry pond water in the front row is stocked, disinfected with quicklime, and then stocked with water after half a month. 2. The soft-shelled turtles are disinfected once with 0.0 1% formalin in the shallow pond, and 300~400 soft-shelled turtles can be stocked per mu. Fish and shrimp, earthworms, animal offal, snail frogs and mussels are the staple foods, and cooked wheat grains, cakes and melons and vegetables are also eaten. When feeding, put the feed into the feeding trough, one end of the feeding trough is put into 4-5 cm deep water, and part of the feed is immersed in the water, which can be fed at 9- 10 in the evening, or it can be delayed day by day and fed in the morning instead. 3. In the warm pool from June to August every year, there are 50 left JNNJF and 50 right JNNJF. Look for turtle eggs in sandy depressions or places with footprints. Those with opaque milky dots on the eggshell are fertilized eggs. When collecting and incubating, the milky white part must face upwards, otherwise the turtle will not hatch. The suitable incubation temperature is about 30℃, the water content is 6%~25%, the sand can be hatched when the burial depth is 5~20cm, and the sand can be hatched in about 45 days. Young turtles should be fed with bait such as Daphnia and filariasis, and eel compound feed can be fed later. 4. Aquaculture is affected by water temperature, and it takes 4-5 years to cultivate commercial soft-shelled turtle. Commercial soft-shelled turtle can be heated in12-1May. Heating with hot spring water or excess hot water from the factory can improve the growth rate of soft-shelled turtle.
