1, choose a good variety. According to the preferences of the general public and the needs of the market, there are many kinds of soft-shelled turtles at present, but generally speaking, soft-shelled turtles weigh 500- 1000 grams, with slim figure, mainly yellow-green color, black-yellow pattern spots on the back, pale yellow-white belly bottom and no spots. Although this kind of turtle grows slower than the turtle with no pattern on the back (commonly known as "smooth plate") and a little pattern on the abdomen, its meat quality and taste are better than the latter, so its value and price are better.

2. Turn off the water quality. The quality of water directly affects the culture effect of soft-shelled turtle. The pond water is too fat and even stinks, which is not only bad for the growth of soft-shelled turtle, but also affects its meat taste. Under normal circumstances, clean river water is injected into the pool every other week or so, accounting for about a quarter of the original pool. Clean up the leftovers on the table regularly. In addition, water hyacinth, which accounts for about half of the whole pond, is planted in the pond. On the one hand, it can purify the water quality, on the other hand, it can provide a hidden and quiet place for turtles to meet their natural living habits as much as possible.

3. Do a good job in disease prevention. In ponds with convenient irrigation and drainage and good escape prevention facilities, 2-3 fry (50- 100g) with basically the same size are stocked per square meter. Usually every 15 days or so, 30-50g of quicklime is poured into the whole pool per cubic meter of water. No trampling or catching turtles in the pond is allowed unless there are very special circumstances. At the same time, bamboo rafts are used to build some drying platforms for turtles to dry their backs.

Although it takes a long time to raise turtles in this way, it takes about three years from fry to 500 grams of commercial turtles, including two hibernation periods, but its economic benefits are good. The feed cost and seedling cost per kilogram do not exceed that of 60 yuan, and the rest belong to income. This method is suitable for family small water culture, and it is a good project of planting at this stage, which is worth popularizing.

Because the tortoise is carnivorous, I certainly feed it some small fish and shrimp, and then feed it with scissors. Other bugs can also be used, such as the bread bug bought in the flower and bird market, but if you only have one, you don't need to buy it, because turtles eat very little, and it is a waste to buy too much, and you have to feed the bread bug. Besides, anything like Mi Chong will do, as long as it can eat.
