How to cultivate field snail artificially

Snail meat is fresh and tender, unique flavor, and rich in protein, fat and phosphorus, calcium, iron and vitamins, favored by consumers. Farmers can obtain considerable benefits by using small water surface or paddy fields to cultivate field snails. The artificial culture techniques of field snails are introduced as follows:

Field snail culture

Living habits: the snail likes to live in the water where it is warm in winter and cool in summer, fresh water, rich bait and soft bottom, especially where there is micro-running water. Field snail is omnivorous, feeding on microorganisms and organic matter in water or tender stems and leaves of aquatic plants. Snails like nocturnal activities and eat vigorously at night.

Site selection: snail farms should choose sufficient water, good water quality, humus soil and convenient transportation. There better be running water. Specification of snail pool: 1.5 li 1.6 m wide, 10 mi 15 m long, and topography can also prevail. Make a ridge around the pool, the ridge height is about 50cm, set up water inlet and outlet at both ends, and install a block to prevent the snail from escaping. At the same time, the sparse planting of aquatic plants such as Yingbai in the culture pond can not only increase the land yield, but also create a good ecological environment for the growth of field snails.

Stocking and management:

1. The stocking density of field snails. Generally, there are 120 fish per square meter, and about 5 silver carp and bighead carp species in summer flowers are cultured in the main body culture. Field snails are usually released in March.

2. Fertilize and bait. The manure was first applied in the culture pond, and the plankton was used as field snail bait. The amount of fertilizer application depends on the bottom quality of the pond. After the snail enters the pond, feed green vegetables, rice bran, fish offal or vegetable cake, bean cake and so on. Green vegetables, fish offal should be chopped, mixed with rice bran and other feed. Vegetable cakes and bean cakes should be soaked and softened so that snails can eat. The amount of feeding depends on the feeding situation of field snails, which is generally calculated according to 1% of the total amount of field snails, which is fed once every 3 days. Feed every morning, the feeding position does not have to be fixed, the feed is put apart. When the temperature is lower than 15 ℃ or higher than 30 ℃, no baiting is needed.

3. Water quality regulation. First, the snail pond should often inject new water to regulate the water quality, especially in the breeding season, to maintain the flow of water, especially in the high temperature season, to adopt running water culture, the effect is better. In the spring and autumn season, it is better to breed with micro-running water. The water depth of the snail pond should be kept at about 30cm; the second is to adjust the pH of the water. When the pH value of pond water is on the low side, 0.15 Mel 0.18 kg quicklime is applied per square meter and sprinkled once every 10 mi 15 days, so that the pH value of pond water is kept at 7 Mel 8.

4. Overwintering management of field snail. When the water temperature reaches 8 ℃, the snail begins to hibernate. When hibernating, the snail drills the soil with the top of the shell, and only makes a small round hole in the soil dough and breathes bubbles from time to time. The field snail does not eat during the overwintering period, but the culture pond still needs to keep the water depth of 10-15cm. Generally, water is exchanged every 4 days to maintain proper oxygen content.

5. Fishing on the market. Field snail after a year of careful breeding, individuals can reach more than 10 grams. The fishing method can be caught in dry ponds; when fishing, large field snails should be selected for snail breeding, which is difficult to prepare for reproduction in the following year.
