How to raise snails

There are many methods for breeding snails. Let me introduce to you some methods for breeding snails!

1. Selection of breeding sites

Many ditches, paddy fields and ponds in rural areas can be used for stocking snails. If it is an open pond, duckweed, water duckweed, water hyacinth and other plants can be raised on the water surface to provide shade, and bamboo poles and wooden strips can be inserted in the pond for snails to live. The green manure on the water can be collected as feed, and snails can be raised to increase income.

2. Water temperature environment for breeding

The optimum growth temperature for snails is 20-25℃. If the temperature is lower than 15℃ or higher than 30℃, the snails will stop eating, and will hibernate in the soil when the temperature is below 10℃.

3. Feed

Snails are omnivorous animals. They can be fed with rice bran, vegetable scraps, melon leaves, animal carcasses and commercial feeds. They generally feed on aquatic plants, soil humus, vegetable melon peels, etc. In fertile paddy fields, fish and snails can be mixed or red duckweed, green duckweed, water hyacinth and other depressions can be raised on the water surface. Less or no feed can be added.

4. Disease prevention and control during breeding

Pesticides should be used as little as possible in the breeding field; even if they are used, low-toxic pesticides should be used, and they should be used on sunny days, preferably half in the rice field and half in the rice field. Organic fertilizers can be used regularly during the growing season, but the principle is to use small amounts and multiple times, and it is not advisable to apply too much fertilizer at one time.

5. Breeding and management of river snails

Field snails are viviparous animals. Their breeding season in the south is from April to May and from September to November every year. Female snails usually give birth in batches. Each snail can produce 20 to 30 small snails each time. It usually takes 14 to 16 months for the female snail to reproduce again after giving birth. The weight of the newly born small snails is about 0.5 to 1.5 grams.

6. Catching and harvesting of snails

When catching snails, you must selectively catch the adult snails and keep more female snails. You can harvest them in batches. The water temperature is higher in midsummer and early autumn. At noon, the snails mostly hide in the soil and grass. They must be harvested in the morning and evening. You can also drain the water before catching them.

The above points are the breeding methods I described for field snail farming.

Farming model of snails

First, add some feces to the breeding pond to cultivate plankton to provide food for the snails. The amount of fertilizer depends on the fatness of the bottom of the snail pond. After the snails are put into the pond, feed them with green vegetables, rice bran, fish viscera or vegetable cakes, bean cakes, etc. Chop the green horns and fish viscera and mix them with rice bran and other feeds before feeding. Soak the vegetable cakes, bean cakes, etc. to soften them for the snails to eat. The feeding amount depends on the snails' feeding situation. It is generally calculated as 1%-3% of the total amount of snails, and feeds are fed every 2-3 days. The feeding time is every morning, and the feeding location does not need to be fixed. Feed is added every other day. When the temperature is below 15℃ or above 30℃, no feeding is required.

Water quality regulation. First, the snail pond should be frequently filled with new water to regulate the water quality, especially during the breeding season. It is best to keep the water flowing, especially in the hot season, and the effect of water culture is better. In spring and autumn, micro-flow water culture is better. The depth of the snail pond should be kept at about 30 cm. Second, adjust the pH of the water. When the pH value of the pool water is low, apply 0.15-0.18 kg of quicklime per square meter, and sprinkle it every 10-15 days to keep the pH value of the pool water at 7-8.

Snail wintering management. When the water temperature drops to 8-9℃, snails begin to hibernate. During hibernation, snails use the top of their shells to drill into the soil, leaving only a small round hole on the soil surface, from which bubbles occasionally come out to breathe. Snails do not eat during the winter, but the breeding pond still needs to maintain a water depth of 10-15 cm. Generally, water is exchanged every 3-4 days to maintain the appropriate oxygen content.

Snails can be released in late March. Ten days before the release of snails, 50 kg to 100 kg of quicklime per mu should be sprinkled throughout the pond to remove wild fish, shrimp and other miscellaneous snails. Three to four days later, organic fertilizers and breeding bait organisms should be piled in the water for the snails to eat. Snails can be purchased from the market or caught by yourself. 100 to 120 snails can be released per square meter, and 4 bighead carps can also be raised in the pond. Before releasing the snails, apply an appropriate amount of manure in the pond to cultivate bait organisms. It is best to release the snails in the early stage of snail reproduction. The snails should be fresh and live with a light brown color, a thin and complete shell, and a domed body. Snails can be raised alone, or some silver carp and bighead carp species can be raised, or snails and loaches can be mixed. When snails and loaches are mixed, there is no need to feed them other feeds, and both snails and loaches can grow normally. Because snails can enrich the plankton, protozoa, invertebrates and aquatic plants in the water, such as rotifers, cladocerans, copepods, chironomid larvae, clams, silk earthworms, etc., and also produce young snails, which are all natural feeds for loaches. The feces excreted by loaches are also good feeds for snails. In addition to eating loach feces, snails also prey on benthic invertebrates and aquatic plants such as filamentous algae, diatoms, euglena, cyanobacteria, and golden algae in the water. Snails and loaches are mixed-cultured. 100-150 kg of snails and 15,000-20,000 loaches are released per mu of fish pond. After 8-10 months of cultivation, 3,500-4,000 kg of snails and 2,000-2,500 kg of loaches can be harvested.
