Freshwater lobster, also known as crayfish, is known as crawfish. In recent years, due to the favorable market prices, the trial of the crayfish pond aquaculture in Binhai County, Jiangsu Province has yielded a yield of about 200 kilograms and has achieved good results. Through two years of practice, the author believes that crayfish farming should pay attention to the following issues: One should pay attention to pond conditions. The crayfish culture pond should not be too deep, generally no more than 1.5 meters. The pond pool should have a certain slope, which is conducive to create a water environment with different depths and water temperatures. At the same time, it can make full use of light energy, increase water temperature, and promote the growth of crayfish. . Crayfish have strong burrowing ability and ability to escape. Pool pods should be compacted and crushed. There must be no caves, and the width should be 1.5 meters or more. Surrounded by asbestos tiles, etc. Double-layer filter to prevent damage, resulting in escape of farmed shrimp. The newly opened pond should also be covered with a layer of 60 to 80 mesh polyene mesh around the slope or in the pool. Second, we must pay attention to planting aquatic plants. Many of the crayfish cultured in Tangkou are transformed from fish ponds without any aquatic plants. In fact, crayfish, like shrimp and crabs, also need aquatic plants. One of the reasons for the failure of some rural households to grow fish is that they have not planted aquatic plants. Water plants can provide shelter for crayfish habitat and shelling, but also can purify water quality, increase dissolved oxygen, and provide fresh natural plant food for crayfish. Among them, the biggest benefit is the reduction of crawfish killing each other. Aquatic grasses mainly include black leaf algae, Elodea, Vallisneria, and water peanuts, accounting for 20% to 30% of the aquaculture area. Third, pay attention to feed feeding. Crayfish are omnivorous, eat animal foods, and bulimia, food intake, lack of food is likely to cause fratricide. At present, chickens, ducks, pigs and other livestock and poultry are cheap, and some farmers feed the whole of the internal organs of livestock and poultry, and do not mix well, causing crayfish to fight each other when they ingest food. The body of water is stinking and smelly and can easily cause diseases. Some farmers failed to breed. It is necessary to adhere to the combination of precision and ingenuity, and to flexibly control the amount of feeding according to the feeding conditions. Fourth, we must pay attention to regulating water quality. Although crayfish have strong survivability and low oxygen tolerance, fresh water quality is still one of the key factors for high crayfish production. In the low dissolved oxygen environment, the crawfish have decreased appetite, slow growth, and can easily cause escape and disease. Once a large number of crayfish are found climbing on the shore or floating on the grass, the water should be changed immediately, especially in the culture. In the later period, change the water 1 to 2 times a week to keep the dissolved oxygen in the water high. Fifth, pay attention to disease prevention and treatment. Crayfish have strong resistance to disease and are not susceptible to disease in natural waters. After high-density pond culture, improper management can also lead to disease, major ciliate diseases, black shank disease, and bleeding. We must adhere to the principle of prevention, and use quicklime (20ppm) on a regular basis to spill it over and use it alternately. Crayfish are very sensitive to pesticides, disinfecting pesticides such as trichlorfon and enemy killings, and also preventing farmland medicines from flowing into shrimp ponds in large numbers, causing unnecessary losses.
