How do soft-shelled turtles reproduce

Soft-shelled turtle, also known as turtle and water fish, is commonly known as soft-shelled turtle. It is not only a delicacy on the dinner table, but also can be used as a traditional Chinese medicine. In addition to wild species, artificial culture is also common in China at present. So, how do soft-shelled turtles reproduce?

How do soft-shelled turtles reproduce?

Under the condition of natural temperature, the soft-shelled turtle that reached sexual maturity began to mate when the water temperature was above 20 ℃. Once mating, multiple spawning. The north spawns 2-3 times a year and the south 4-5 times a year. The spawning period is from May to August, and the spawning peak is from June to July. Soft-shelled turtles like a quiet environment and usually spawn in the middle of the night. The soft-shelled turtle spawns by digging holes to lay eggs and burying them with sand after delivery, so it is necessary to build a sand spawning ground around the pond.

Second, what are the artificial culture techniques of soft-shelled turtle?

1. Construction of bait platform

It is best to place it on the edge of the pond around the pond and at an angle of 30-45 degrees with the water, which helps the soft-shelled turtle to find food and avoid interference. Clean the bait table and its surroundings with a small irritating disinfectant and a sterilized brush before each feeding, and disinfect it every 3 days.

two。 Production and delivery of bait

The addition of fresh ingredients is generally 10% to 40%. When using fresh materials, they must be disinfected, cleaned and used now to avoid corruption and deterioration. Feeding should be in the form of feeding, and the bait is 2cm away from the surface of the water. The soft-shelled turtle is timid, so the interference to it should be minimized when feeding. The amount of feed should be eaten in 1-1.5 hours as the standard, and the remaining bait should be collected in time for other use. The feeding time in the high temperature season should be finished before sunrise and start feeding at sunset.

3. Water quality regulation

The aquaculture water should be changed and discharged regularly, and the appropriate amount of water for each change should be no more than 1x3. If there are conditions, the effect of microflow water culture will be better. In the process of breeding, regularly use chlorine dioxide preparation 0.5~1ppm, bleaching powder 2~3ppm, strong chloroform 1~2ppm, quicklime 15~40ppm to sprinkle disinfection in the whole pond, and sprinkle about 5ppm photosynthetic bacteria preparation in the whole pond 2 or 3 days after application, which can play the role of water transfer, once or twice a month.

4. Set up a back tanning table

In the pond about 1 meter from the bait platform around a 1.5-meter long and wide frame, plant water hyacinth. Water hyacinth developed roots, can absorb harmful substances in the water and play a role in water transfer, but also conducive to the soft-shelled turtle hidden, sun back, enjoy the cool and so on. The culture ponds with less sloping land should set up a sun-drying back table in the pond.

5. Regular patrol of ponds

The purpose of clearing the dead soft-shelled turtle in time is to keep abreast of the turtle's food intake, growth activities, diseases, pond water quality, facilities and so on. The dead soft-shelled turtle in the pond should be fished out and buried or incinerated in time, and the diseased soft-shelled turtle should also be isolated and treated in time.

At present, the market value of soft-shelled turtle is recognized by consumers. As long as the culture conditions are available and the culture technology is really mastered, there is still a good market for culture of soft-shelled turtle.
