Daily management experience of cultured snails

With the continuous improvement of people's living standards, more and more people spend the night, and most young people spend the night with more than three or five friends. Snail is popular in the midnight snack industry, and many people like to eat it. And it tastes great.

Daily management experience of cultured snails

1. Aquaculture water

Snails have strong adaptability and few diseases. As long as they avoid the toxicity of a large number of pesticides and chemical fertilizers, many flat canals, beaches, pits, paddy fields, ponds and other ordinary water bodies in rural areas can be released. Keep the sediment thickness 10cm-15cm, the area is not limited. If there is an open body of water, a small amount of duckweed and water lotus can be cultivated on the surface of the water, some long rattan melons and vegetables are planted around the pond for shade, and bamboo tails, branches or stones and grasslands are arranged in the water for snails to live in concealment. Ten days before the snail was put, quicklime was applied to remove wild fish, shrimp and other miscellaneous snails in the whole pond according to the dosage of 15 ha of 50kg-100kg per hectare. 3-4 days later, organic fertilizer and reproductive bait were piled in the water body to feed the snail.

2. Restocking of snails

The rearing of snails should be completed in the early stage of field snail breeding. The source of field snail: one is field collection, the other is market collection. Choose fresh snails with light brown color, thin and complete shell and dull body. In general, the amount of seed snail 0.1kg-0.5kg per square meter in natural extensive water body can be increased by 2-3 times in intensive culture pond. The cultured field snail can be released alone, or some silver carp and bighead carp species can be raised or mixed culture of field snail and Loach can be adopted.

3. Feeding and management

The extensive culture mode in natural waters only needs to maintain the fatness of the water body and apply appropriate amount of organic fertilizer such as barnyard manure, chicken manure, cow manure, pig manure or rice straw to meet the growth needs of snails. In the case of high-density intensive breeding, artificial bait must be put in. Field snails do not have high nutritional requirements, so rice bran, wheat bran and soybean powder are simply used to prepare the high-quality feed of field snails in the proportion of 60%, 25% and 15%.

According to the feeding and climatic conditions of the snail, the snail has a strong appetite within the suitable growth temperature (that is, 20 ℃-28 ℃) and can be fed once every two days, each time 2% of the body weight. 3%. When the water temperature is in the range of 15 ℃-20 ℃ and 28 ℃-30 ℃, feed twice a week, about 1% each time. When the temperature is lower than 15 ℃ or higher than 30 ℃, there is little or no investment.

4. Daily management work

It is strictly forbidden to flow into water sources polluted by pesticides and chemical fertilizers; to prevent the invasion of ducks, snakes, rats, birds and other enemy pests; and to remove weeds and grass roots in the water in time. Usually take the form of micro-flow, keep the water level around 30cm. Increase the water flow in the high temperature season to control the rise of water temperature and ensure sufficient dissolved oxygen. In the cold weather, the snail hibernates in the soil. At this time, the water is changed once or twice a week, and some chopped straw is sprinkled into the water to facilitate the snail to survive the winter.

Prospect of field snail culture

Snail meat is a kind of nutritious natural health food, and it is also known as beauty food abroad. It contains 10.3% protein and 1.2% fat, as well as vitamins, calcium, iron and other essential elements. The nutrition of field snail meat is better than that of chickens, ducks, geese and pigs, and is no less than that of crucian carp and sea cucumbers. Snail meat can nourish kidney yin, clear eyes and clear brain, enhance muscle elasticity, delicate skin and so on.

Field snail can be used as home meat, can also be processed into a series of food, cooking a variety of medicinal meals, disease prevention and treatment. At present, the natural growth of field snail is far from being able to meet the market demand, and the field snail culture grows fast, the yield is high, and there is a wide range of ways to cultivate field snail "money".

Field snail culture cost

Because the snail culture does not need to feed a lot of bait, the cost of the bait is also very low. Therefore, basically does not need much cost, as long as you have a field in your home, then the rest is snail seedlings.

The benefit of breeding field snail is remarkable. 667m2 can produce 400kg in specializing in field snail. At present, the market price is 30.4 yuan / kg. Calculated by 3.5yuan / kg, the output value of 667m2 can reach 1400 yuan. In addition, a small amount of grass carp can be mixed in Tianluo pond to increase the benefit per unit area of snail pond. Because the snail culture does not need to feed a lot of bait, the cost of the bait is also very low. Therefore, the net profit of snail culture is about 1000 yuan / 667m2, and the benefit is considerable.

Nutritional value of field snail

Rich in protein, with the ability to maintain potassium and sodium balance; eliminate edema. Improve your immunity. Lower blood pressure, buffer anemia, conducive to growth and development. Calcium is the basic raw material for bone development, which directly affects height, regulates the activity of enzymes, participates in the activity of nerves and muscles and the release of neurotransmitters, regulates the secretion of hormones, regulates heart rhythm, reduces cardiovascular permeability, controls inflammation and edema, and maintains acid-base balance.

Rich in copper, copper is an indispensable micronutrient for human health, which has an important impact on the development and function of blood, central nervous system and immune system, hair, skin and bone tissue, brain, liver, heart and other internal organs. Rich in iron, iron is an essential component of hematopoiesis, suitable for the treatment of iron deficiency anemia.

Dietotherapy value

1. Clearing heat: snail can clear heart and purge fire, clear heat and remove annoyance, and eliminate heat toxin in the blood. Can treat hot knot adverse urination, jaundice, beriberi, hemorrhoids, hematochezia.

2, diuresis: contains diuretic ingredients, can eliminate water and sodium retention in the body, diuresis and detumescence. It can treat edema, swelling and pain of eyes, swelling and poison of sores.

3. Quench thirst: moisturize the throat to remove dryness, making people refreshing and comfortable. It can cure thirst.

4. Relieving alcohol: snail can relieve the toxicity of ethanol and excrete quickly after relieving alcohol.

From the above analysis, it is not difficult to see that the breeding prospect of field snail is very good, and its market demand increases every day. Field snail not only tastes very good, but also has a certain nutritional value.
