The snail's farming methods include pool breeding, rice paddy farming, and fish polyculture. The ponds cultivated by special pools should have small areas, soft soil, and adequate water sources. The pond can be suitably grown with some aquatic plants such as bamboo shoots, bamboo shoots and mushrooms to fully utilize the land and create a hidden ecological environment for snails. The quality of water in aquaculture ponds is one of the keys to the success or failure of farmed snails. First of all, we must ensure that the water quality is excellent. Any water containing a large amount of iron and sulfur must not be used. Because of the high iron content of water, the mortality rate after stocking seedlings is very high, red rust is also attached to the spiral shell that can survive, and even snail meat is reddish brown. Sulfur quality also uses snails with sulfur odors and is untenable. Aquaculture water is best in a slightly turbid river or pond natural water, not too clear and transparent, the water should be rich in natural food and adequate oxygen. Mountain snails are very sensitive to the amount of dissolved oxygen in the water. When the dissolved oxygen is 3.5 mg/l, they do not feed. When they fall to 1.5 mg/l, they will die. Therefore, the aquaculture water must be fresh and can use semi-fluid water. Farming is ideal. The optimum temperature for snail breeding is 20°C-26°C, and the food intake is strong. When the temperature of the water rises to 30°C-33°C, the snail will dive into the earth to avoid the heat and will not grow or move. The meat is also hard and boring. Therefore, we must pay attention to adjust the water temperature below 26 °C. Cultured water depth is generally 30 cm. In order to increase the water temperature in winter, it can be reduced to about 20 cm. This amount of water is not only required for fertility in snails, but also has a defensive effect. Field snails live in a soft and rich soil environment, mainly feeding on animals and plants that breed on the bottom of water and corrupt organic matter. Most people think that snails ingesting soil is actually not the same. He is using microbes or other corrupt materials to sow together with soil. In the case of insufficient natural food, artificial diets such as vegetative wastes of vegetables, rice bran, and fish can be fed. Each feeding amount is 10%-30% of the snail weight, and the feeding time can be performed in the morning. If it is found that the snails in the rearing ponds overflow after the meat has shrunk to the outside, the shellfish powder may be infiltrated into the feed. If it is deep inside the shell of the spiral shell, it is due to lack of food, should increase the amount of feeding. At the same time, when the pool water is warm and turbid, the snails will stop feeding, and secrete a lot of mucus, sometimes causing snails to die. Therefore, muddy water should be avoided from entering the pool. The paddy field also supports snails, and it is best to use snails that are not wet and wet throughout the year. The organic fertilizers and weeds in rice fields can supply snails. When the stocking density is high, they can be supplemented and fed with some artificial baits. In the shade of rice, the snail grows in summer. Therefore, it is a kind of simple and labor-saving farming method to raise the snail in paddy fields, but it is necessary to pay attention to avoid using pesticides, otherwise it will produce poison to snails. The snails can be mixed with the first-instar catfish species and feed their feed. After being decomposed in the soil, snails can be used as snail feed. However, it is not appropriate to polyculture with second-instar eel, as this individual's eel will ingest the snail shellfish. It can also be mixed with other fish or aquatic animals. Sometimes, in order to increase the production of famous aquatic products, snails are used as high quality feed for herring, turtles, and quail. In the natural state, snails can grow to 6-8 grams in the same year, and artificially cultivated individuals can weigh 12-15 grams. The first three to four months have seen the fastest growth, but gradually become slower, and no longer grow after two years. Therefore, snails must seize the opportunity during the artificial breeding period, and fully feed them to make them grow in a relatively short period of time. Such snails are large, soft and delicious, and they are not as natural as they are. The yield is also high. The catch method The snails captured by the snails are not only hand-pulled into the pond but also can be captured by a hand-caught net. The diameter of the net is 20 cm and the mesh is 2.8 cm. When the fish is caught, small nets can be kept in the pond for continuous culture. If the aquaculture pond has a large area, stir-fried rice bran can be mixed with clay to form a dough and put into the pool. When the snail smells the aroma, it will feed in a cluster and can be picked up and left to stay small or caught with a net.
