Second, turtle culture technology
1, build a fish pond
(1) To build a pond, it is necessary to choose a pond with quiet environment, windless sunshine and convenient irrigation and drainage for breeding. If it is an autotrophic turtle farm, it needs to build five kinds of breeding ponds, namely, new school, young school, young school, 3-year-old school and adult school.
(2) The soil in the pond is preferably clay or loam. If there is no sand at the bottom of the pond, mix some sand. At the edge of the culture pond, a drying platform and a feeding platform should be built to provide a place for turtles to dry their backs and eat. Asbestos tiles and bricks should be used to build an escape wall with a height of 1m around the aquaculture pond.
2. Selection and stocking of crucian carp fry
Selection of fry: order from regular farms or local aquatic markets, or order online. But be careful not to buy from small vendors, because the fry in vendors' hands are different in size and the source channels are not clear. After buying it back, turtles are prone to illness and death.
Stocking: No matter where you buy fry, you can't put them into the breeding pond immediately. You should first keep them in a cage 15 days or so to observe the situation of turtles. If turtles don't feel any discomfort or abnormality, they can be stocked on a large scale. The stocking density depends on the size of the culture pond and other factors, and 2-3-year-old turtles can be put per mu 100 kg- 150.
3. Temperature control
The optimum temperature for the growth of soft-shelled turtles is generally 30℃-32℃, and the food intake of soft-shelled turtles is directly proportional to the temperature, but the maximum temperature should not exceed 32℃, and the temperature should be kept as stable as possible.
4, the choice of feed
(1) Animal feed: The feed for soft-shelled turtles can be made from the leftovers of livestock and poultry discarded in restaurants and cooking, as well as snails, small fish, shrimps and loaches caught in rice fields or river ditches, as well as earthworms and insects in the fields.
(2) Plant feed: a small amount of plant bait, such as corn flour, bean dregs, melons and fruits, bran, etc. , can be added to turtle feed, and then processed and stirred evenly before feeding.
5. Feed supply
When using fresh feed, be sure to disinfect and clean it and eat it on the spot to avoid deterioration. When feeding, you should feed 2 cm -3 cm away from the water. This is because turtles are timid, so we should try to minimize the interference with them when feeding. Feed should be eaten within one and a half hours. In hot season, feed should be eaten before sunrise and at sunset.
6. Water quality management
Turtles are very strict about water quality, because most turtles live in water, and water quality is very important for the growth of turtles. Therefore, water should be changed every 8- 10 days, and the water level in the culture pond should be excluded from 20 cm to 25 cm each time, and then filled with water, and the water transparency in the culture pond should be controlled at 30 cm to 35 cm.
However, the water in the adult fish pond should be changed every four days, and a small amount of green plants such as water hyacinth and Eichhornia crassipes can be planted in the water, which can improve the water quality and make turtles grow better.
To sum up, if farmers want to breed high-yield soft-shelled turtles, they must master correct breeding techniques and scientific management methods. I hope this article can help everyone.
