Where does soft-shelled turtle live? How to reproduce? How to raise it in captivity?

Soft-shelled turtle, commonly known as soft-shelled turtle, also known as ball fish, water fish, is an egg-laying amphibian and reptile. It is not only a delicacy on the table and a high-quality material for a first-class feast, but also can be used as a traditional Chinese medicine. Where does it live because it has so many uses? How to reproduce? How to raise it in captivity?

Where does the soft-shelled turtle live?

Soft-shelled turtles live mainly in lakes, ponds, reservoirs, triangles and slow-moving rivers.

Soft-shelled turtles are amphibious and breathe through their lungs, so there should be a sufficient area of land beach around or in the center of the turtle pond so that it can carry out land activities. The living habits of soft-shelled turtle can be summarized as "three joys and three fears", that is, Xi Jing is afraid of shock, Xi Yang is afraid of the wind, Xi Jie is afraid of dirty. The soft-shelled turtle is sensitive to the sound of the surrounding environment. As long as there is a little movement around, the soft-shelled turtle can quickly dive into the underwater silt, so the environment of the turtle farm or turtle pond must be kept quiet. If the soft-shelled turtle is often frightened, it is very disadvantageous to its growth and reproduction.

How do soft-shelled turtles reproduce?

Under the condition of natural temperature, the soft-shelled turtle can not reach sexual maturity until the age of 4 to 5 years old, and begin to mate when the water temperature is 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. The spawning time is usually in the middle of the night (06am), which is related to the turtle's preference for a quiet environment. The spawning mode of soft-shelled turtle is to dig holes to lay eggs, which is buried with sand after delivery, so a sandy spawning ground should be set up around the pond.

Third, how to raise it artificially?

1. Placement and cleaning of bait table

The bait table is best placed on the edge of the pond around the pond and at an angle of 30-45 degrees with the water surface, 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.

2. 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. Grow green on the surface of the water and build a sun-drying 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. Patrol the pond regularly to get rid of the sick and dead turtle in time.

The purpose of pond patrol is to keep abreast of turtle 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.
