CATDOLL : CATDOLL: Is farming snails profitable?

1. Is it profitable to breed snails?

Snails need water, the environment is limited, and we also have to consider sales, profits, etc.

I suggest you take a look at Quezhiling Peacock Breeding.

2. Is it profitable to raise screws?

That depends on your skills and market. You will definitely make money, otherwise there would be no such job as raising screws in the world.

3. Is it profitable to breed stone snails and field snails?

Commercial production of snails can be raised in rice fields or in specially dug breeding ponds. There are no strict requirements for the equipment for small-scale breeding for the purpose of entertainment. Ceramic tanks, basins, pots or wooden barrels can be used for breeding. However, in order to observe their living conditions frequently, it is best to use transparent plastic or glass or plexiglass aquariums with wire mesh as a cover for ventilation.

The box does not need to be too big. A small rectangular aquarium of 35 cm*20 cm*25 cm is enough. The bottom of the box should be padded with 8~10 cm thick soil containing more humus. It is best to add some silt dug from the bottom of the pond. On top of it, add about 10 cm deep river water or pond water. If tap water is used, it must be placed in a basin or bucket for 2~3 days before use. However, spring water containing iron, sulfur and other substances cannot be used. Put some algae or other aquatic plants in the box, and then put a few large stones, 5~8 cm above the water surface, so that the snails can rest on them.

The number of snails raised does not need to be too large. Generally, 6 to 10 are enough. It is best to start with young snails. You can catch them yourself, either by hand from the pond or ditch, or by hand with a scoop net. The diameter of the scoop net is about 20 cm, and the mesh size is 1.5 to 2 cm. If the pond is too large to reach, you can mix fried rice bran and soil, knead them into pellets and throw them in the pond or stream. The snails will come to eat when they smell the fragrance, and you can use a scoop net to catch them.

In the snail breeding box, you can also raise a few small carps. They can be raised together with the snails without interfering with each other, which is more conducive to viewing.

The feed for field snails can be fresh and tender leaves and duckweed, with a small amount of soybean powder, fine rice bran, bran powder, etc. It has a small appetite and does not need to be fed too much, otherwise the remaining bait will pollute the water quality, which is not conducive to its growth and survival.

After 30-40 days of feeding, the small snails will grow into medium-sized snails, and their weight can reach 4-6 grams. At this time, the water depth in the box should be appropriately increased by 3-5 cm, and a few duckweed and water lilies should be added. This will provide food for the snails and provide them with a hiding place. The feed can be sprinkled on the water surface.

When the snails grow up to be adults, the small fish should be removed. Feed should be given twice a day and the remaining bait should be removed every day to keep the water fresh. Replace about half of the old water every 2 to 3 days and add clean water of the same temperature.

Snails are very afraid of high temperatures. If the water temperature rises above 30 degrees in summer, you must try to lower the water temperature and add new water. When the water temperature drops to about 10 degrees in winter, you should take warming measures to keep it from dropping any further, otherwise the snails will not survive easily. The pH of the water should be alkaline, and the pH value should be kept at 7-8. In addition, the oxygen content in the water should be maintained, and the water should be changed every 2-3 days. Is it a large-scale breeding? Snails are rich in nutrition and have a wide range of utilization value. They are a high-quality animal protein feed resource that needs to be developed and utilized.

1. Nutritional value of snails According to measurements, the dry matter in fresh snails is 5.2%, the dry matter contains 55.36% crude protein, 15.42% ash, including 5.22% calcium, 0.42% phosphorus, 4.56% salt, etc. There are 2.84% lysine, 2.33% methionine and cystine. It also contains rich B vitamins and minerals. In addition, in addition to a small amount of protein, the snail shell has a mineral content of about 88%, including 37% calcium, 0.3% phosphorus, and about 4% sodium salt. It also contains a variety of trace elements. In the practice of the feed industry, snail shells are mineral elements like shells. In the practice of the breeding industry, snail shells are mineral supplements like shells.

2. Farming technology of snails: Snails usually grow in rice fields, lakes, ponds, swamps and ditches. When they are used naturally, their life patterns can be mastered and they can be caught when they are of the right age. The key points of artificial farming technology of snails are as follows:

1. Living habits of river snails River snails often live in lakes, ponds, paddy fields and slow-flowing rivers and streams that are warm in winter and cool in summer, with soft bottom soil and abundant bait. The most suitable water temperature for its growth is around 20~25℃. It stops feeding when the water temperature is below 15℃ and above 30℃. It buries itself in the soil and hibernates when the water temperature is below 10℃. When the water temperature returns to above 15℃, it comes out of its hole to feed again. Artificial breeding of river snails can be carried out in special ponds, or in natural rice fields, swamps, ditches, and can be mixed with fish. However, the breeding water must be non-toxic, harmless and pollution-free. If breeding is carried out in rice fields, pesticides cannot be applied, plowing and harrowing cannot be carried out, and wire or plastic screens should be installed at the inlet and outlet for control.

2. Collection and selection of snails Parent snails for breeding can be collected from rice fields, ponds or ditches. The selection criteria for breeding parent snails are: light color, thin shell, round body, large size, no damage to the shell, and complete cover of the shell mouth disc. Female snails are large and round, with the left and right antennae of the head of the same size and extending forward; male snails are small and long, with the right antennae of the head thicker and shorter than the left antennae, and the end is bent to the right inside, and the bent part is the reproductive organ. April, May and October each year are the reproductive seasons of field snails. Generally, each litter can produce 20 to 30 snails, and as many as 40 to 60. More than 150 can be produced in a year. After 2 to 3 weeks after birth, the snails weigh 0.025g and can start to eat. Generally, they can reproduce after one year of feeding. In a special pond for field snails, 100 to 150 snails can be placed per square meter; if natural waters are used, 20 to 30 snails can be placed per square meter.

3. Feed sources for feeding and management of snails are relatively wide, generally vegetables, potatoes, bean cakes, rice bran, fish and shrimp residues, and other animal offal, scraps, etc. can be fed. During the feeding process, pay attention to the water quality. If the water quality is found to be polluted, it should be removed immediately and refilled with new water. If the disc cover of the snail's shell is sunken into the shell, it means that it is due to insufficient bait or hunger. The amount of feed should be increased in time; if the disc cover of the snail's shell is found to shrink and meat is overflowing, etc.
