Economic analysis and precautions for farming snails
First, the economic analysis of cultured snails Baiyu snail is a variant species of brown cloud amon snail, commonly known as white meat snail, is a mollusk, gastropoda, terrestrial shellfish, hermaphrodite, is a unique mollusk of our country.
A. The economic value of snails:
1. Food: Snails have a fleshy, high protein, rich in more than 20 amino acids. It has been determined that each 100 g of snail meat contains 60.4 g of crude protein, 3.8 g of crude fat, 4.5 g of crude fiber, 18.9 g of nitrogen-free extract, 9.6 g of ash, and calcium, phosphorus, iron, zinc, boron, and selenium. Alkaloids, alkaloids, phenols, soft acids, lactones, and various vitamins, as well as more than 30 kinds of enzymes, are known as "soft gold." It is a good universe for aerospace and athletes and nutritious food. Deng Xiaoping, a reform planner, praised snail food and said: "Snail food has made up for a gap in the country and it must be well developed."
2, Medicinal: "Compendium of Materia Medica" has a detailed record of the medicinal use of snails: cold, taste salty, into the large intestine, lung, liver, kidney, with nourishing yin and kidney, heat detoxification, removing phlegm, diuretic, swelling , Asthma, dehydration, pediatric umbilical wind, only nosebleeds, through deafness, hoarding, belching, rectal prolapse, diabetes, red and white dysentery, nephritis, tuberculosis embolism. In addition, snails also contain lectins, which have a non-negligible effect on the treatment of blood diseases and vascular diseases.
3. Beauty: The snail enzyme isolated from the digestive glands of snails is biologically referred to as a “micro-scalpel†and is widely used in nutrition and health care, makeup and beauty industry, light industry textile, and fermentation brewing industry.
4. Feed: The meat, shells and entrails that meet the edible standards when processing snail meat can be dried and dehydrated, and ground and crushed to make feed.
B, snail breeding efficiency.
Snail breeding is a science and technology poverty alleviation project. It has less investment, miscellaneous food, convenient breeding, and quick results. Its advantages are:
1. Small investment: A 15-m2 house can raise 3-40000 snails, and an acre of land can produce 6-8 tons of fresh snails.
2, food miscellaneous: all green feed can feed snails. Consumed less feed.
3, easy to raise: daily investment can manage 30,000 snails in two hours, the temperature can be normal breeding at zero 20 degrees.
4. Quick results: From the time of hatching to the sale of 35 grams to 50 grams, it takes 6 months, during which 50 grams of concentrate and 500 grams of green feed are consumed.
C, market conditions for snails.
There are four potential markets for snails:
One is export earnings. The annual demand for Chinese snail meat in the international market is 3-5 million tons, and the demand in Europe and America is the largest;
The second is to extract snail enzymes. Snail enzyme is an important raw material for bioengineering, genetic engineering and pharmaceutical industries. It can be used to make nutritious liquids, white jade milk, super skin care water, white shampoo shampoos, and more.
The third is for people to eat. Snail meat is delicate and contains a variety of medicinal ingredients such as amino acids, enzymes, and vitamins. It can nourish the body with regular meals. The Beijing-only hotel needs 100 tons of live snails and 500 tons of restaurants in Shanghai.
The fourth is to do feed additives. Snail viscera and shell can be processed into feed additives instead of fish meal.
Second, culture snails Note:
A, pay attention to market.
Snail is a high-protein, low-fat nutritious food. However, in most parts of China, there is no habit of edible snails, and most of them are processed and exported. At present, there are only a few white jade snail processing plants in China, and the total amount of processing and export is limited. Therefore, local friends who have no habit of eating edible snails and haven’t implemented sales cannot be blindly cultured.
B, pay attention to management.
Snails are an intermediate parasite of human and animal parasites and various pathogenic bacteria, and have a greater harm to crops. If cultivated snails are poorly managed, they will cause major disasters in agricultural production. Therefore, China’s relevant departments have long stipulated that it is forbidden to introduce white jade snails from abroad.
C, pay attention to the trap.
At present, there are some confusions in the snail breeding industry in China, and there are also many false information, mainly price information and market sales information. Some of them have greatly surpassed the international and domestic market levels and in fact are far from selling at such a high price. The current market guide price for each snail is 2-5 yuan. Beyond its price should be carefully introduced to prevent fraud.
D, pay attention to feeding.
When feeding snails, care should be taken not to feed the snails with pesticides to contaminate the feed. This can lead to excessive levels of pesticides, heavy metals, etc., or contain banned drugs, which will affect exports.
