Prevention and control of diseases and insect pests in cultured snails

I think many people are very familiar with Tian snail. With the rapid development of the midnight snack industry in recent years, Tian snail is more popular with everyone in the midnight snack. Many young people like to make an appointment with a few friends at night and just sit together and chat when they are free.

What is a snail?

As the development and utilization of indigenous species, field snail culture has been developed in recent years. Field snails belong to the phylum Mollusca, Gastropoda, Oncomellidae and Oncomelania. There are 4 species, namely, Chinese round field snail, Chinese round field snail, bloated round field snail and Ursuli round field snail. At present, the main breeding is the Chinese round field snail. Snails are generally suitable for breeding in rice fields, shallow ditches, lowlands, wetlands and other places. Field snails do not have high requirements for breeding sites, generally with a little rectification in shallow water, soft mud bottom waters with a lot of humus can be cultured, and it is better to have certain micro-flow conditions.

Prevention and control of diseases and insect pests in cultured snails

So far, few diseases and pests of field snails have been found, and not many have been reported. However, here are some suggestions for reference:

The main results are as follows: 1. The suitable temperature for field snail culture is 10-40 ℃, and the optimum temperature is 20-28 ℃. More than 40 ℃ will cause death, and less than 10 ℃ will go into hibernation. Attention should be paid to the prevention of high temperature in summer, because the water in the paddy field is shallow, the water temperature may reach the upper lethal temperature in summer, and the content of organic matter in the bottom of the mud overwintering in winter should not be too high, otherwise it is easy to produce toxic substances and affect the snail overwintering.

2. Field snails are sensitive to the amount of dissolved oxygen in water. Normal life requires dissolved oxygen in water to be more than 4 milligrams per liter. When it falls to 3.5 milligrams, appetite will decline, and when it drops to 1.5 milligrams, it will cause death.

3. The breeding season of field snails is from June to July (where there are conditions, they will lay eggs again in autumn). If you consider breeding yourself, it is best not to raise carp in the rice fields where field snails are raised, otherwise small field snails will be eaten by carp.

4. The use of pesticides in rice fields should not be used as much as possible; that is, low toxic pesticides should be used in combination, and should be used in sunny days; it should be used in half of rice fields.

5. Organic fertilizer can be used regularly in the growing season, the principle is a small amount of multiple times, should not be fertilized too much at one time.

6. It can be considered that the economic benefit of field snail is better if it is mixed with leech, Loach and rice field eel.

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.

The Dietotherapy value of Field snail

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.

In the process of field snail culture, the prevention of field snail disease is also very important. In the aquaculture industry, if you want to get a high yield, disease prevention is essential. Only by mastering certain prevention methods can you be handy in breeding.
