CATDOLL : CATDOLL: What is the economic value of snails?

1. What is the economic value of snails?

Snails are a very valuable wild animal resource. They are a special economic animal that does not compete for labor, food and arable land, requires little investment, has low costs, quick results, high returns, is easy to raise, has a wide range of feed, has a high reproduction rate, low morbidity, has a strong ability to withstand hunger, is silent, odorless, pollution-free, and is easy to promote. It has special economic significance and development value.

Snail meat is tender and nutritious. It is a high-quality food with high protein, low fat and almost zero cholesterol. According to analysis, 100 grams of snail meat contains 18 grams of high-quality protein and only 0.22 grams of fat. Moreover, its protein contains all kinds of amino acids necessary for the human body. In addition, the digestive tract of snails contains more than 30 different enzymes, which can not only help humans and other animals to enzymolyze food and participate in metabolism, but also enzymolyze plant cell walls, making it an ideal assistant for plant genetic engineering.

2. What are the benefits of snails to the human body?

The Compendium of Materia Medica has long recorded the use of snails to treat diseases. Modern Chinese medicine also recognizes that snails have the effects of clearing heat, detoxifying, reducing swelling, and treating thirst. They have an auxiliary therapeutic effect on diseases such as diabetes, hypertension, hyperlipidemia, tracheitis, prostatitis, malignant sores and cancer. Efficacy: reduce swelling and treat sores, shrink anus and reduce prolapse, and promote urination. Application and indications: treat swelling and toxins; treat sores and initial stage; treat scrofula; treat toothache; Recently, the Russian Academy of Sciences' Advanced Nervous Activity and Neurophysiology is currently trying to use the nerve tissue of snails and other mollusks to treat Parkinson's disease. Parkinson's disease is caused by the gradual degeneration of substantia nigra cells in the brain and the cessation of secretion of the neurotransmitter dopamine. Its main symptoms are muscle rigidity and tremors in the hands and feet. Studies have found that mammals have a weak ability to reject mollusks. Researchers implanted snail nerve tissue into the brains of mice, and the mutual compatibility can last for more than 6 months. After further improving the technology, Russian experts have been able to fuse snail nerve tissue with the brain tissue of mice with Parkinson's disease, and gradually restore the damaged brain function of mice. Based on the above results, Russian experts will use the nerve tissue of mollusks to conduct experimental clinical treatment on volunteers with Parkinson's disease in the next stage of research.

The diet is now open, and snails are the last taste." Li Shizhen, a medical scientist in the Ming Dynasty, also highly praised the medicinal value of snails in "Compendium of Materia Medica" for its heat-clearing, detoxification, and swelling. According to the research report of French Samba, snail meat is tender, high in protein and fat-free, so snails are also called green organic food without pollution. Studies have shown that it is rich in more than 20 kinds of amino acids needed by the human body and more than 30 kinds of biologically active enzymes, as well as more than ten trace elements such as calcium, iron, zinc, and selenium, and its cholesterol content is zero.

Snail meat is delicious, unique in flavor, fragrant and tasty. Modern nutrition and medical circles have recognized that snails have the effects of clearing heat, detoxifying, reducing swelling, relieving asthma, nourishing the skin, and curing thirst.

【Excerpt】National Compilation of Chinese Herbal Medicines

Snail's Fear

Afraid of salt,

Dialysis is the process by which water in the body moves from the lower salt content of the body to the higher salt content of the body.

Salt causes snails to lose water and die of dehydration

[Example]He walks as slowly as a snail.

According to scientists, the fastest speed a snail can crawl is about 12.2 meters per hour. Nowadays, people often use the word "snail crawling" to describe a very slow speed.

The snail's natural enemy

The most deadly natural enemy of snails is fireflies (the larvae eat the snail's body, and the adults lay eggs in the snail's body). There are also snail beetles and mice. Some natural enemies that are not easy to find are parasitic wasps and flour mites. Flour mites should be the white insects you mentioned. Many of them live in groups and feed on the body fluids and epidermal mantle of snails or slugs. They do not cause much harm in a short period of time, but if they grow on a large scale, they will cause significant harm to snails. They should be eliminated as much as possible. When the snails are inactive, use raw bones with residual meat to attract them. Take out the bones after one morning. Doing this frequently can reduce the parasitism of flour mites! The only reason for this situation is that your breeding environment is not good! There is no timely cleaning of residues and excrement, or the humidity and temperature are too high.
