Hello, please help inform the living habits and breeding methods of stone snails, thank you

It prefers to live in shallow to medium water with sunlight and clear water, and feeds on algae, mosses and aquatic plants. Likes to attach to stones. It can be collected in all seasons. In general, it is okay to stock according to the above living conditions.

Stone snails can be marketed after one year of breeding.

After a year of careful raising, the young snails can reach 10g-20g, and the hatched snails can also reach more than 5g specifications.

When harvesting snails, the method of catching large and keeping small ones and listing them in batches is adopted, and the adult snails are selectively ingested, and the young snails are retained and some female snails are selected and retained, so as to achieve natural replanting, and there is no need to put seedlings in the future. According to their living habits, in the high temperature season of summer and autumn, choose bamboo branches and grass handles that rotate on the shore or in the water body in the early morning and night; In winter and spring, pick up at noon on a sunny day. In addition, snails can also be harvested by means of digging in the pond or picking up the dry pond by drainage.

The transportation of snails is very simple, it can be packed in ordinary bamboo baskets, wooden barrels, etc., or it can be packed in woven bags, as long as the snails are kept moist during transportation to prevent exposure.

1. Choose a good snail species. Generally, it is better to choose a large outer circle, a thin shell with more meat, fewer threads, and gray-black.

2. Prepare the breeding pond. The breeding pond must have the following requirements: first, the bottom must have a certain thickness of silt; second, there are algae, red grass and other aquatic plants on the water surface; Third, there are shade objects for stone snails to inhabit underwater and around, such as wooden strips, bamboo branches, stones, etc.

3. Stocking time and density. The good reproductive period of the stone snail is between March and November, the female snail gives birth in batches, each time it can reproduce 20 30 young snails, and a female snail can reproduce more than 150 in a year. According to this law and characteristics, the stocking time can be carried out in batches from 3 to 11 months.

The stocking density of snails can be determined according to the specific situation, if it is cultivated in natural waters such as paddy fields, fish ponds, swamp fields, etc., it is advisable to put 600 snails per mu; If the artificially excavated pond is used for breeding, the snails should be put more, and 9,000 to 12,000 snails can be put per mu.

4. Feeding of feed. Stone snails feed on the leaves of aquatic plants, algae, etc. The feed can be aquatic plants, algae, melon leaves, green vegetables, animal carcasses, rice bran, bran, etc.

5. Harvesting method. The harvesting of snails should be carried out in batches, and should not be carried out during the peak period of snail pregnancy and farrowing. The peak period of pregnancy and littering in the year is early June, mid-August and late September, and at this time, the harvest should also be selected to fish for adult snails, and more female snails should be left to facilitate reproduction, increase yield and economic benefits.

Hello, it shouldn't work, snail breeding environment.

1. Flowing water.

We see that stone snails generally live on stones in streams and rivers, because the water of streams and rivers is living water, which is suitable for the growth and reproduction of stone snails.

Whether it is a snail or a snail, it is necessary to use flowing water, which means that the water must be kept flowing in order for the snail to live. If the water does not flow, it is difficult for the snail to grow and reproduce.

2. The water quality is clean.

The clean water here does not mean that it should reach the level that people can drink, the main thing is that it is not seriously polluted and there are no artificial chemical components. For example, the tap water at home is also too suitable for the growth of stone snails. Therefore, the water quality of the place where the snail is raised should be clean and not too turbid.

3. There are stones.

Stone snails, as the name suggests, have a lot to do with stones. Stone snails like to cling to stones, do not like to grow in silt, if you breed a lot of stones, you are eligible for breeding. If it is full of silt, it is recommended that it is best not to raise it, and you can consider raising snails.

4. Cool. The breeding place should not be too hot, for example, the water is too shallow and too hot, and the stone snail will die of heat and cannot reproduce normally. Therefore, the water should have a certain depth, and there should be some vegetation around it to cool down.

It can be raised, and the stone snail can be raised in deep or shallow water.

Stone snails can also be farmed in deep water.

Temperature: Stone snails can survive in water around 20 to 28 degrees, and too high or too low a temperature will affect their activity. Water Quality:

Stone snails need to survive in an alkaline and calcareous water environment so that their shells are strong and unbrittle. Food: Stone snails can eat algae, humus, microorganisms, etc. in water, and can also eat artificial feed such as fish food, shrimp food, or snail food.

Stone snails are easy to breed, and they are not very demanding in terms of growing environment. However, in order to successfully farm, there are also some basic conditions that need to be met, such as a temperature between 20 and 28 degrees, an alkaline environment, a certain amount of calcium in the water, and plenty of food, and it is better if there is a certain amount of sediment containing organic matter in the water.

1. Temperature: The snail can adapt to the temperature of about 20 degrees, and it is best to keep the temperature between 20 degrees and 28 degrees. If the water temperature is too high or too low, it will affect their activity. If the water temperature exceeds 40 degrees, then the snail is completely inactive.

2. Water quality: Stone snails like to live in an alkaline environment, so they need to keep the pH value above seven. And the growth of stone snails needs to be in water with a certain amount of calcium.

If the pH level in the water is too low or the calcium content is low, the shell of the snail is likely to become fragile and fragile.

3. Food: There are many foods that can be eaten by stone snails. These include plants in the water, such as algae in the water. It also includes some humus in the water, or microorganisms. Of course, you can feed some fish food, shrimp food or food scraps during artificial feeding.

4. Stone aquatic plants: The growth environment of stone snails is generally in the river or pond where there are stones or aquatic plants at the bottom of the water, and they like to attach to the roots of these stones or aquatic plants, and such an environment can be simulated when breeding.

When breeding snails, you can choose lakes and ponds that contain more humus in the waters as breeding places, when breeding, you need to select healthy female snails and male snails to mate, give birth to snails, and then breed snails, in the process of breeding, you can provide moss, wheat bran and other foods for snails.

1. Site selection

When cultivating snails, you need to choose a place. Stone snails are suitable for growing in the environment with more humus at the bottom of the water, so you can choose lakes, ponds and marshes with lush aquatic plants and finch rivers to breed stone snails, before breeding, you need to build barbed wire or fishing nets on the breeding site to avoid the snails escaping in the process of breeding.

2. Get the snails

Healthy snails need to be obtained before they can be farmed. The snail is an ovoviviparous animal, and its fertilized eggs will develop into a snail in the body of the female snail, so when obtaining the snail, you can choose to grow healthy male and female snails, so that they can mate and fertilize, and after waiting for a year, the snail will give birth to the snail.

3. Scientific feeding

In the process of breeding, it is also necessary to provide scientific food for stone snails. In the process of growth, the snail will eat microorganisms or phytoplankton and moss at the bottom of the water, and when feeding the snail, it can provide nutritious foods such as green vegetable leaves, fruits, rice bran, wheat bran, soybean cake and fish meal.

4. Precautions

When providing food for the snails, you need to pay attention to the amount of feeding, when the water temperature is in the range of 20-28 degrees, provide feed for the snails every two days, the feeding amount is controlled at 2% of the body weight, when the water temperature is lower than 20 degrees or higher than 28 degrees, you can feed twice a week, the feeding amount is controlled at 1% of the body weight, and when the temperature is lower than 15 degrees or higher than 30 degrees, you need to stop feeding.

<> pond bottom has silt, water surface has aquatic plants and other suitable for breeding snails, snails can be cultivated in paddy fields, ditches, swamp fields, creeks and other places, stocking in phases and batches in March to November, 600 snails can be bred per mu of breeding in natural waters, and 9000-12000 snails can be bred per mu of artificial excavation pool. Breeding snails can be fed with aquatic plants, algae, rice bran, bran, etc., and the harvesting of snails should be carried out in batches, leaving more female snails to facilitate reproduction.

1. Site selection and seed selection

1. There are many places suitable for artificial breeding of snails, such as paddy fields, ditches, fish mounds, swamp fields, creeks, etc. Regardless of the first breeding snail, the bottom of the breeding pond must have a certain thickness of silt, the water surface of the breeding pond has algae, red weed and other aquatic plants, underwater and around the shade for the snail to inhabit, such as bamboo branches, stones, etc.

2. Choose snails with large body, thin shell, more meat, less threads, and gray-black for breeding, and it is not recommended to breed snails with small and long tips, thick shells, less meat, and more threads. Snail seeds can be purchased directly from the market, or you can go to the pond and field to pick up.

Second, the breeding density

The good reproductive period of snails is between March and November, and the stocking time can be carried out in batches from March to November. The stocking density of snails can be determined according to the specific situation, if it is cultivated in natural waters such as paddy fields, fish ponds, swamp fields, etc., 600 snails can be put per mu, and 9000-12000 snails can be put into artificial excavation pools per mu.

3. Feeding

Stone snails feed on the leaves of aquatic plants, algae, etc. If it is stocked in fertile fish farms and water knowledge fields, it is not necessary to feed them specifically; If it is kept in a lean ridge or a specially dug pool, the feed can be aquatic plants, algae, melon leaves, greens, animal carcasses, rice bran, bran, etc. Stone snails like to be active and feed at night, and the amount of feeding can be increased appropriately when feeding at night.

The suitable temperature for the development of snails is 20-28, and the appetite is thriving, and it can be fed every two days, and the amount of each feeding is 2%-3% of body weight. When the temperature is less than 15 or higher than 30, less or no feeding.

Fourth, harvest

The harvesting of snails should be carried out in batches, and should not be carried out during the peak period of snail pregnancy and farrowing. The peak period of pregnancy and littering of stone snails in the year is to return to the finch in early June, mid-August and late September, at this time the harvest should also be selected to fish for adult snails, and leave more female snails to facilitate reproduction and increase yield.

Artificial breeding technology of stone snails:

1.Aquaculture water bodies.

As long as a large number of pesticides and chemical fertilizers are avoided, many flat canals, streams, pits, rice fields, ponds and other ordinary water bodies in rural areas can be stocked. If the pond is excavated 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). Keep the thickness of the sediment 10 cm to 15 cm, and the size of the area is not limited.

If it is an open water body, a small amount of red weeds and water lotus can be cultivated on the water surface, and some long vine melons and vegetables are planted around the pond to build a shelter for shade, and bamboo tails, branches or stones, and grass are arranged in the water for stone snails to hide and inhabit. 10 days before the stone snail is put in, according to the amount of 50 kg and 100 kg per mu, the whole pond is applied quicklime to remove wild fish, shrimp and other miscellaneous snails, and after 3 days and 4 days, organic fertilizer and breeding bait are stacked in the water body for the snail to feed.

2.Stocking of snails.

Choose a fresh snail with a light brown color, a thin and complete shell, and a blunt dome. Generally, in the natural extensive water body, the snail kilogram per square meter is put into the kilogram, and the intensive culture pond can increase the amount of seed by 2 times and 3 times. Cultivated snails can be stocked alone, or some silver carp and bighead carp fingerlings can be intercultured or polyculture of stone snails and loaches can be adopted.

3.Feeding management.

The extensive breeding method in natural waters only needs to maintain the water fertility and apply an appropriate amount of organic fertilizers such as manure, chicken manure, cow manure, pig manure or straw at regular intervals to meet the growth needs of stone snails. In the case of intensive high-density culture, artificial bait must be used. The snail does not have high nutritional requirements, and it is simply used with rice bran, wheat bran, and soybean flour in the proportion of % and 15% to form the superior feed of the snail.

According to the feeding situation and climate conditions of the snail, within the suitable temperature for growth (i.e., 20 28), the snail has a strong appetite, and can be fed once every two days, and the feeding amount is 2% 3% of body weight each time. When the water temperature is in the range of 30, feed twice a week, each time to about 1%. When the temperature is lower than 15 or higher than 30, then less or no vote.

5. Daily management.

It is strictly forbidden to flow into water sources polluted by pesticides and fertilizers; Prevent the invasion of predators such as ducks, snakes, rats, and birds; Remove weeds and grass roots from the water in a timely manner. Usually take the form of micro-flowing water, and keep the water level at about 30 cm. Increase the water flow during the high temperature season to control the increase in water temperature and ensure that the dissolved oxygen in the water body is sufficient.

In cold weather, the snail enters the soil to hibernate in the soil, at this time, change the water 1 time 2 times a week, and sprinkle some chopped straw on the water body to help the snail overwinter.
