Crayfish culture is a popular culture industry today, and many details in the process of culture are ignored by both new and old farmers. The newly cultivated pond is also very knowledgeable. First of all, we should choose a place with convenient transportation, sufficient power supply, high-quality clean water and convenient drainage. All these conditions are met, that is, digging shrimp ponds. The shrimp pond should face north and south, that is, it is long from north to south and narrow from east to west. This pond is easy to dissolve oxygen. New and old farmers must pay attention to the fact that the width of shrimp ponds does not exceed 35 meters. It is too wide, so crayfish will not move to the middle, and crayfish are also afraid of water. Because the water quality will deteriorate at any time and lack oxygen, crayfish will not risk their lives to stay away from the shore if there are no obstacles or lush aquatic plants in the middle.

The slope of the shrimp pond is1; 3. It is convenient for crayfish to quickly climb to the shore and exhale under anoxia. If it is too steep, it is difficult for crayfish to exhale quickly. Crayfish is weak under lack of oxygen and encounters cliffs on the way to escape. In this environment, even if you don't die, you have to peel off the skin.

Few people pay attention to the details of crayfish pond construction. This small problem belongs to Lao Wang's initiative, and Baidu can't figure out this detail. This is all observed in the process of culture, that is, a groove of 10-20 cm is opened on the long-term water level line of10-20 cm, which is convenient for crayfish to make holes. Careful farmers can observe that it is difficult to see the holes made by crayfish on steep slopes, smooth and grassless slopes. Crayfish caves can be seen everywhere on the flat hillside, where there are weeds and grooves.

After the shrimp pond is built, 20 kilograms of quicklime should be sprayed per mu, and then the water level should be kept at 30 cm. Grass should be planted after 6-7 days, Elodea should be planted in the pond built years ago, Kuroshio should be planted in the pond built in June-July, and water peanuts and water spinach should be planted around the pond in spring.
