CATDOLL : CATDOLL: How to raise snails, how to raise snails

1. How to raise snails and how to raise snails

1. It is best to control the water temperature between 20-25 degrees when breeding snails.

2. pH: Snails need to grow in an alkaline environment, and an acidic environment will harm them.

3. Hardness: Water with a certain amount of calcium can make the snail's shell strong and not easy to break.

4. Food: Farming snails requires providing sufficient food, such as fish feed, shrimp feed, snail feed, etc.

5. Silt: Snails need to survive in mud and sand, and are best raised in an environment with mud and sand at the bottom.

2. Farming technology and water quality requirements for snails

Snails need to be cultured in clean water without impurities and humus, and the water must be running or flowing. The length and width of the breeding pond can be 10-15×1.5-1.6 meters. The embankment needs to be 20 cm higher than the water body. Inlets and outlets should be opened at the diagonals of the pond, and escape-proof nets should be installed. Remove excess silt 7-10 days before releasing the snails, disinfect with quicklime water, and then release 100-120 snails per square meter.

3. Where can snails be farmed in Guangzhou?

There are some in the Liuxi River area of ​​Conghua, but the exact location is unclear.

4. Can snails be raised in May and June?

Snails belong to the gastropod mollusk, which is easy to grow and breed, and grows and reproduces quickly. It is suitable for growing and breeding in ponds, ditches, and paddy fields. According to the practice of farmers, the production of fresh snails per mu in paddy fields is about 2,000 kilograms, and the output value per mu exceeds 4,000 yuan. The development of snail farming is a good way for rural areas to get rich. 1. Growth habits In late spring and early summer, the water temperature rises to above 15℃, and the snails crawl out of the holes where they hibernate and begin to eat and grow. June to August is the peak season for spawning. Female snails aged 1 to 2 years old give birth to 20 to 30 offspring, and those aged 4 and above give birth to 40 to 50 offspring. After one year of breeding, the young snails can grow to sexual maturity. It likes to live in waters that are warm in winter and cool in summer, with soft bottom soil, rich bait, and fresh water. It has a mixed diet, and microorganisms and organic matter in the water, aquatic plants, young stems and leaves are the main food. It is active at night and eats more. 2. Selection of breeding sites: Snails have strong vitality and disease resistance. They can be raised in ditches, paddy fields, and shallow ponds with running water sources, or in ponds. The snail pond is generally 2 to 3 meters wide and 10 to 15 meters long. The pond is surrounded by ridges with a height of 0.5 meters. Inlets and outlets are opened at both ends of the pond, and fences are installed to prevent snails from escaping. 3. Source of seedlings and release of seed snails: June to September is the season for snails to lay eggs in large quantities. Seedlings can be picked up in fertile rice fields and ditches, or commercial snails can be purchased in the market. Fresh female snails weighing 15 to 20 grams, with light brown color, thin shells, round bodies, and blunt tails are selected as seed snails. Generally, seedlings can be raised from April to November. For release in natural waters, 10 spawning female snails can be released per square meter. If immature small snails are released, they should be released in a ratio of 2:1 between male and female. Female snails are larger, with rounded bodies and concave shells; male snails are slightly smaller, with longer bodies and convex shells. After one year of breeding, young snails can be put on the market as commercial snails. If a pond is specially built for breeding seedlings, 100 to 130 female snails can be placed per square meter for laying eggs, and 70,000 to 80,000 snails can be placed per mu of pond. Young snails weigh 0.02 to 0.03 grams 5 to 7 days after birth and start to eat. After one year of breeding, they are sexually mature and can reproduce offspring. 4. Feeding and management For breeding in ponds, 20 cm thick fertilizer mud is laid on the bottom of the pond, and new water is injected. Water lilies, small gourds, red and green duckweed, etc. are placed on the water surface for the snails to eat. Small bamboo poles or wooden strips are inserted in the pond for the snails to live and lay eggs, and then the snails can be released. There are abundant sources of bait for field snails. Small animals, plants, algae, weeds, and tender leaves in the water are all natural baits. During the vigorous growth period of young snails, rice bran, wheat bran, tofu dregs, cooked sweet potatoes, small insects, small fish and shrimp, animal offal, and scraps should be added. If conditions permit, compound feed can also be fed. The daily feeding amount is 1.5% to 2% of the snail body. Feed once every day from 8 to 9 o'clock. Large baits should be chopped and fed. Change the water regularly to keep the water fresh. When the water temperature is above 30℃, inject new water frequently to deepen the water level. It is generally better to keep the water depth at 30 cm. In winter, increase the water level at night and lower the water level during the day to allow direct sunlight to heat up. At the same time, apply some pig manure and stable manure to increase the temperature and fertilize the water quality. Field snails are very sensitive to pesticides, herbicides, petroleum and industrial wastewater, so they should be well avoided. 5. Catch and market After one year of breeding, field snails generally weigh 15 to 16 grams, and large ones weigh 20 grams, and can be caught and marketed. The fishing method can be dry pond catching or shallow water level catching. When catching, select the larger female snails to be kept as parent snails for breeding in preparation for the next year's breeding of young snails. 6. Wintering Management When the water temperature drops to 8-9℃, the snails begin to hibernate. During hibernation, the snails burrow into the soil, leaving only a small round hole on the soil surface, emitting bubbles from time to time for breathing, and not eating or moving. However, the breeding pond must maintain a water depth of 10-15 cm, and generally replace the water every 4-5 days to maintain an appropriate oxygen content, so that the snails can safely overwinter.

5. Is there any development in breeding mountain snails?

Many people have tried to breed them, but all have failed. Currently, there is almost no research on mountain snails, and the encyclopedias on the Internet are almost all nonsense! During World War II, the original data was destroyed by the Japanese army, and then domestic scholars did not include mountain snails in the scope of research. Breeders have devoted a lot of enthusiasm, but it is extremely difficult to do something unprecedented without the participation of scholars, not to mention that there is no big money coming in, and breeders are just on a whim, and in the end, nothing comes of it! Not long ago, a scholar in Yunnan did some research and supplemented some information! The mountain snails in southern China belong to the family of sulphur and the family of short sulphur. At present, the more recognized ones in the market are the Guangdong sulphur, followed by the Guangxi sulphur and the Vietnamese sulphur. The Guangdong sulphur, that is, the Guangdong mountain snail, is the largest and has the highest market price, which can reach 50 yuan per catty during holidays! Mountain snails mainly grow in streams, and the water quality requirements are very high. At the same time, the oxygen content requirements of the water quality are also very high, which makes it increasingly difficult for the current mountain snails to hide after environmental pollution! In fact, the mountain snail has a strong reproductive ability. As long as the conditions are right, it can reproduce densely! The short-tailed snail is a female snail. Female snails conceive and reproduce all the time. The main breeding season is spring and autumn. They die when the water temperature exceeds 40 degrees. They do not eat when the temperature is below 15 degrees. Ultraviolet radiation can also cause death. The living conditions are extremely harsh. If we want to achieve artificial reproduction, we still need to work together! It can be predicted that in the next few years, before artificial breeding is successful, either the mountain pit snail will be replaced by other foods, or the price will become higher and higher...
