1, choose a good variety. According to the preferences of the general public and the needs of the market, there are many varieties of soft-shelled turtles at present, but generally speaking, soft-shelled turtles weigh 500? 1000g, slim, mainly yellow-green, with black and yellow pattern spots on the back, yellowish white at the bottom of the abdomen, without spots. Although this turtle grows slower than the turtle with no pattern on the back (commonly known as "smooth plate") and star 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. The pond has convenient irrigation and drainage and good escape prevention facilities, and the stocking scale is 50? 100g) Carassius auratus fry 2 with basically the same specifications? Three. Generally every 15 days or so, 30? Sprinkle 50 grams of quicklime all over the pool at a time. 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.
