What conditions are needed to breed snails and what are the main foods to feed them?

1. Water environment: The water for breeding must be non-toxic and pollution-free. Choose semi-flowing water breeding. The dissolved oxygen content of the water must be above 3.5-4 mg/L. If the dissolved oxygen content is below 3.5 mg/L, the snails' appetite will decrease. 2. Feed formula for breeding snails: 60% rice bran, 25% wheat bran, 15% soybean meal, or 60% rice bran, 20% fish meal, and 20% corn.

1. What conditions are needed to breed snails?

1. Water environment

(1) The water used for aquaculture must be non-toxic and pollution-free.

(2) The snails can be cultured in a semi-flowing water system, and the dissolved oxygen content of the water must be above 3.5-4 mg/L. If the dissolved oxygen content is below 3.5 mg/L, the snails' appetite will decrease, and when the dissolved oxygen content is below 1.5 mg/L, the snails will die.

(3) The bottom of the pond should be covered with 10-15 cm thick sediment. Some water lilies can be planted on the water surface. Branches, bamboo poles and stones can also be placed in the water to provide a habitat for snails.

(4) The water depth must be controlled at 30-40cm, the water pH value must be controlled at around 7-8, and the water can be changed 1-2 times a week.

(5) 10 days before feeding the snails, 50-100 kg of quicklime can be used per mu of pond to remove wild fish, shrimp and other snails. After 7-10 days, 450-500 g of chicken manure and straw segments can be applied per square meter to improve water quality.

(6) Nylon nets must be installed at the inlet and outlet to prevent snails from escaping.

2. Feeding

(1) Feed formula for snails: 60% rice bran, 25% wheat bran, 15% soybean meal, or 60% rice bran, 20% fish meal, 20% corn.

(2) Feeding method: In an environment of 20-28°C, the snails can be fed once every two days, and the amount of each feeding is 2-3% of their body weight. In an environment of 15-20°C or 28-30°C, they can be fed twice a week, and the amount of each feeding is 1% of their body weight. In an environment with a temperature below 15°C or above 30°C, they can be fed a small amount of food, or not fed at all.

2. What are the main foods to feed farmed snails?

1. The food sources of field snails are very wide. In nature, field snails generally feed on young aquatic plants or plankton. Farmed field snails can be fed with cow dung or chicken dung, which can also promote the growth and reproduction of plankton or aquatic plants in the water, indirectly providing more food sources for the growth of field snails.

2. Vegetables or rotten fruits can be mashed and fed to snails. Farmers can also use wheat bran, soybean meal, and corn flour in a ratio of 6:3:1 as snail feed. The high protein content of this type of feed can accelerate the growth of snails. General poultry feed can be fed to snails, but the price is relatively high and it also contains a lot of soybean meal. Tofu dregs are also a good feed for snails. You can use part of the wine lees mixed with wheat bran or soybean meal to feed them together.

3. There are three kinds of feed that can be fed, namely fermented farmyard manure, some grass and concentrate. Concentrate is a high-protein feed mixed with feed or soybean meal. The amount of feed for snail seedlings should be a little more, mainly to increase the organic matter content of the water body. The ratio is 250 kilograms of fermented farmyard manure, 200 kilograms of concentrate, and 600 kilograms of grass per mu. In the later period, the daily amount of concentrate feed must be fed according to 1% of the total weight of the seedlings, and the farmyard manure must also be fed according to 1% of the weight of the first seedlings. After the snails give birth, the feeding amount can be appropriately increased according to the actual situation.

I want to raise snails. Are there any farms in Guangxi? I ​​would like to ask an expert for technical advice or to join me.

There are farms in Guangxi.

Snail farming technology

Snails are a traditional aquatic product in my country. They are tender and delicious, with a unique flavor. They are rich in protein, fat, phosphorus, calcium, iron and vitamins. They are a nutritious food favored by consumers. Farmers can obtain considerable economic benefits by breeding snails in small water surfaces or rice fields. The following is an introduction to the breeding technology of snails:

I. Reproduction and living habits of river snails 1. Reproduction season: In late spring and early summer, when the water temperature rises to 15℃, river snails crawl out of their hibernating holes to feed and grow. They begin to reproduce in April. April to September is the season for river snails to lay eggs, and July to August is the peak period for river snails to breed. Female snails aged 1 to 2 years can lay 20 to 30 eggs, and female snails aged 4 or above can lay 40 to 50 eggs. The young snails grow rapidly after birth and can reach sexual maturity in 1 year.

2. Living habits: River snails are gastropod mollusks that prefer to live in waters that are warm in winter and cool in summer, with soft bottom, abundant bait, and fresh water. They especially prefer to gather in places with slight currents. River snails are omnivorous animals that feed on microorganisms and organic matter in the water or young stems and leaves of aquatic plants. They prefer to be active at night and feed vigorously at night.

2. Selection and construction of snail breeding sites Snail breeding sites should be selected in places with sufficient water sources, good water quality, humus soil and convenient transportation, preferably with running water. The specifications of snail ponds are generally 1.5 meters to 1.6 meters wide and 10 meters to 15 meters long. The pond should be surrounded by ridges, which are about 50 cm high. Inlets and outlets are set at both ends of the pond, and nets are installed to prevent snails from escaping. At the same time, some aquatic plants such as wild rice should be planted in the breeding pond, which can not only improve the utilization rate of the pond, but also create a good ecological environment for the growth of snails.

3. Stocking quantity and feeding management 1. Stocking density The stocking of field snails is generally carried out in March, and generally 100 to 200 are stocked per square meter. At the same time, about 5 summer carp and bighead carp can be raised per square meter.

2. Fertilization and feeding The breeding pond should first be fertilized with some feces 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, they should be fed with vegetables, rice bran, fish viscera or tea cakes, bean cakes, etc. The vegetables and fish viscera should be chopped and mixed with rice bran and other feeds before feeding. Vegetable cakes, bean cakes, etc. should be soaked and softened for the snails to eat. The feeding amount depends on the snails' feeding situation. Generally, it is fed at 1% to 3% of the total amount of snails. Feeding should be done once every 2 to 3 days. Feeding should be done in the morning, and the feeding location does not need to be fixed. When the temperature is below 15℃ or above 30℃, no feeding is required.

3. Water quality regulation (1) Fresh water should be added to the snail pond regularly to regulate the water quality, especially during the breeding season. The water should be kept flowing. In spring and autumn, micro-flow aquaculture is preferred; in hot seasons, flowing aquaculture is more effective. The depth of the snail pond should be maintained at about 30 cm. (2) Regulate the pH of the water. When the pH of the pond water is low, apply 0.15 kg to 0.18 kg of quicklime per square meter, once every 10 to 15 days, to keep the pH value of the pond water at 7 to 8.

4. Management of snails during winter 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 water depth of the breeding pond still needs to be maintained at 10 cm to 15 cm, and the water needs to be changed every 3 to 4 days to maintain an appropriate oxygen content.

5. After one year of careful breeding, the snails can generally reach more than 10 grams. The method of fishing can be dry pond fishing. When fishing, choose large snails to keep as parent snails for breeding in preparation for the next year's breeding of young snails.

Key points of artificial breeding technology of river snails.

1. Pond

When choosing a pond for breeding snails, you must ensure that the water quality is good, preferably running water, because the dissolved oxygen content in such water is relatively high. If farmers choose to use old ponds for breeding, they should pay attention to draining the pond water first and cleaning the pond silt before breeding.

To prevent snails from escaping during artificial breeding, farmers should build a row of stalks around the pond and install protective equipment at the water inlet and outlet. Before breeding snails, you can also grow some aquatic plants in the pond to create a natural ecological environment that is more conducive to the growth of snails.

2. Delivery

The time for releasing snails is around March every year. When the water temperature rises above 15℃, the snails will crawl out of their holes to look for food. In April, the snails begin to reproduce. Snails grow quickly and usually mature in one year. In April of the following year, the snails will give birth.

3. Food

Snails like to stay in places with more aquatic plants and eat some microorganisms in the soil or aquatic plants, such as moss. On this basis, farmers also need to feed them some feed artificially, such as vegetable leaves and rice bran.

4. Temperature

The most favorite temperature for snails is between 20℃ and 28℃. If the water temperature is lower than 10℃, snails will enter hibernation. If the water temperature exceeds 30℃, snails will burrow into the soil and not eat food. Snails are not heat-resistant, and once the temperature is too high, they will die.
