CATDOLL : CATDOLL: When is the best time to start breeding snails?

The time for stocking snails is generally in March.

The technical requirements for breeding field snails are very high. The specific breeding techniques and methods are as follows:

1. Selection of snail breeding sites

The snail breeding site should be selected in a place with sufficient water source, good water quality, humus soil and convenient transportation. It is best to have running water.

Construction of breeding pond. The specifications of snail pond are generally 1.5-1.6 meters wide and 10-15 meters long, and can also be based on the terrain. The pond is surrounded by ridges, which are about 50 cm high. Inlets and outlets are opened at both ends of the pond, and nets are installed to prevent snails from escaping. At the same time, aquatic plants such as wild rice stems are sparsely planted in the middle of the breeding pond, which can not only increase the land output rate, but also create a good ecological environment for the growth of snails.

2. Stocking quantity and feeding management

1. The stocking density of snails is generally 100-120 per square meter. At the same time, about 5 silver carp and bighead carp are raised per square meter for the main breeding. The stocking time of snails is generally in March.

2. Fertilization and feeding. 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 feeding situation of the snails. It is generally calculated as 1%-3% of the total amount of snails, and feed once every 2-3 days. The feeding time is every morning, and the feeding location does not need to be fixed. Feed is put every other day. When the temperature is below 15℃ or above 30℃, no feeding is required.

3. Water quality adjustment. First, the snail pond should be frequently injected with new water to adjust 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, it is better to use micro-flowing water for culture. 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.

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 10-15 cm. Generally, water is exchanged every 3-4 days to maintain the appropriate oxygen content.

[Edit this section] Breeding technology Snails are a kind of freshwater snails produced in China and are a top-grade health food. In recent years, as the natural production of snails has gradually decreased, the snail market has continued to be optimistic. At present, artificial breeding has begun in Guangdong, Fujian and other regions. Many farmers have taken the breeding of snails as a way to start a business and vigorously developed it. Now we briefly introduce the breeding technology of snails. 1. Habits of snails Snails like to live in water environments with humus-rich bottom mud, such as lakes, ponds, fields or slow-flowing ditches with lush aquatic plants. They often feed on microorganisms and humus in the soil, phytoplankton in the water, young aquatic plants, moss, etc. They also like to eat artificial feed, such as fruits and vegetables, vegetable leaves, rice bran, wheat bran, soybean powder (cakes) and various animal scraps. Snails are cold-resistant and afraid of heat. The suitable temperature for their life is 20℃~28℃. When the water temperature is lower than 10℃ or higher than 30℃, they will stop eating and drill into the soil and grass to avoid cold and heat. When the water temperature exceeds 40℃, the snails will be scalded to death. 2. Reproduction of snails Snails are dioecious. The method of distinguishing male and female snails is mainly based on the shape of their right antennae. The right antennae of male snails bend inward to the right (the bent part is the male reproductive organ). In addition, female snails are large and round, while male snails are small and long. Snails are ovoviviparous animals with a unique reproductive method. The embryonic development and the development of young snails are completed in the mother's body. From the fertilized eggs to the production of young snails, it takes about a year to gestate in the mother's body. Snails lay eggs in batches and begin to reproduce from March to April every year. While producing young snails, the female and male parent snails mate and fertilize, and at the same time, they nurture the young snails to be produced the following year in the mother's body. A female snail produces about 100 to 150 young snails throughout the year. 3. Artificial breeding 1. The adaptability of farmed snails is strong and they have few diseases. As long as they avoid the poisoning of large amounts of pesticides and fertilizers, they can be raised in many flat rivers, streams, pits, rice fields, ponds and other ordinary water bodies in rural areas. If you dig a special pond for breeding, choose a place with convenient water source and humus soil to build a pond (if the soil is not suitable, it is best to apply mixed compost to improve it first). Keep the bottom mud thickness 10 cm to 15 cm, and the area size is not limited. If it is an open water body, a small amount of red duckweed and water lotus can be cultivated on the water surface, and some long-vine melons and vegetables can be planted around the pond to build a shed for shade. Bamboo tails, branches or stones, grass, etc. are arranged in the water for farmed snails to live in seclusion. Ten days before the release of farmed snails, apply quicklime to the whole pond at a dosage of 50 kg to 100 kg per mu to remove wild fish, shrimp and other miscellaneous snails. After 3 to 4 days, pile organic fertilizers and breeding bait organisms in the water for farmed snails to eat. 2. Stocking of seed snails It is best to complete the stocking of seed snails in the early stage of farmed snail reproduction. The sources of snails are: one is wild collection, the other is market collection. Choose fresh snails with light brown color, thin and complete shells, and blunt dome bodies. Generally, 0.1 kg to 0.5 kg of snails are placed per square meter in natural extensive water bodies, and the amount of seeding can be increased by 2 to 3 times in intensive breeding ponds. Farmed snails can be raised alone, or some silver carp, bighead carp and silver carp can be raised together, or snails and loaches can be mixed. 3. Feeding and management In the extensive breeding method in natural waters, it is only necessary to maintain the fertility of the water body and apply an appropriate amount of organic fertilizers such as manure, chicken manure, cow manure, pig manure or straw every once in a while to meet the growth needs of snails. In the case of high-density intensive breeding, artificial bait must be used. Snails do not have high nutritional requirements. Simply use rice bran, wheat bran, and soybean powder in a ratio of 60%, 25% and 15% to make a superior feed for snails. According to the snails' eating habits and climate conditions, when the snails are in the suitable growth temperature (i.e. 20℃～28℃), they have a strong appetite and can be fed once every two days.

The time for stocking snails is generally in March.

The technical requirements for breeding field snails are very high. The specific breeding techniques and methods are as follows:

1. Selection of snail breeding sites

The snail breeding site should be selected in a place with sufficient water source, good water quality, humus or bright soil and convenient transportation. It is best to have running water.

Breeding pond construction. The specifications of the snail pond are generally 1.5-1.6 meters wide and 10-15 meters long, and can also be based on the terrain. The pond is surrounded by ridges, which are about 50 cm high. Inlets and outlets are opened at both ends of the pond, and nets are installed to prevent the snails from escaping. At the same time, aquatic plants such as wild rice stems are sparsely planted in the middle of the breeding pond, which can not only increase the land output rate, but also create a good ecological environment for the growth of snails.

Snail seeds are planted in spring for three months every year. Guangxi Wuzhou Dilan Snail Breeding Base
