What do snails eat? How can I make a living?

English name Snail Latin scientific name Fruticicolidae, Genus and Classification, Mollusca, Gastropoda and Snail are the animals with the most teeth in the world. Although its mouth is only the size of a needle tip, it has 25,600 teeth. There is a small hole in the middle of the snail's small antenna, which is its mouth. There is a serrated tongue inside, which scientists call "toothed tongue". Snail is not a biological classification name. Generally speaking, what does it mean? ? ? ? All kinds of animals in the family, also broadly including some animals in other families of Gastropoda (including slugs, etc. ) There is no distinction between aquatic snails and terrestrial snails in general western languages. In Chinese, snails only refer to terrestrial species, although they also include many animals of different families and genera, but they are similar in shape. Snails have a relatively fragile low conical shell. Different kinds of shells are left-handed and right-handed, with obvious heads. There are two pairs of antennae in the head, the last pair of longer antennae has eyes at the top, and the ventral surface has a flat and wide abdominal foot, which moves slowly, secretes mucus under the soles of the feet, reduces friction and helps walking, and mucus can also prevent the invasion of general insects such as ants. Snails generally live in wet places and hide in plants to avoid the sun. Snails living in cold regions hibernate, and species living in tropical regions hibernate in dry seasons. The mucus secreted by them during hibernation will form a dry film to close the shell mouth, and the whole body will be hidden in the shell until the temperature and humidity are suitable. Snails are distributed almost all over the world, and different kinds of snails have different sizes. African snails can be as long as 30 cm, while northern wild species are generally less than 1 cm. Snails generally feed on leaves and buds of plants, so they are an agricultural pest. But there are also carnivorous snails that feed on other kinds of snails. The French used snails to cook, so they cultivated a Burgundy snail with thick meat, which was 40-50 cm long and weighed more than 40 grams. Now this artificially cultivated edible snail has spread all over the world with French cooking. Snails are hermaphroditic, some species can reproduce independently, but most species need two individuals to mate and exchange sperm with each other. Ordinary snails lay eggs in wet soil, and usually after two to four weeks, small snails will break out of the ground. It can lay 100 eggs at a time. Snails have many natural enemies, such as chickens, ducks, birds, toads, turtles, snakes, hedgehogs and so on. Fireflies mainly feed on snails. Snails can generally live for 2-3 years, up to 7 years at the longest, but most of them may become food for other animals in that year. Snails have different symbolic meanings in different cultures. In China, snails symbolize slowness and backwardness. In western Europe, it symbolizes tenacity and perseverance; Some people predict the weather by the action of snails. Finns believe that if snails have long tentacles, it means good weather tomorrow. Snails have high edible and medicinal value. Rich in nutrition and delicious, it is an advanced nutritional tonic with high protein, low fat and low cholesterol and rich in more than 20 kinds of amino acids. Snails belong to Gastropoda terrestrial mollusks, and there are many kinds in the world. According to relevant data, there are 40,000 species of snails in the world. Snails are distributed in all provinces and regions of China, living in forests, shrubs, orchards, vegetable gardens, farmland, houses, parks, gardens, temples, mountains, plains, hills and other places. However, there are few species with feeding and edible value. Snail, as a kind of human food and animal protein feed with high protein and low fat, has attracted more and more attention. The whole body of snail includes shell, head, neck, shell membrane, foot, viscera, sac and so on. The snail shells on its back are of different shapes and sizes, such as pagoda, gyro, cone, sphere and tube. At present, white jade snail, covered snail, scattered snail, open snail and brown cloud agate snail all have their own unique shapes. Living habits Snails like to live in a dark, humid, loose and humus-rich environment, most afraid of direct sunlight and sensitive to environmental reactions. The optimum environment is 16 ~ 30℃ (23 ~ 30℃, the fastest growth and development); Air humidity 60% ~ 90%; The humidity of the feeding soil is about 40%; The pH value is 5 ~ 7. When the temperature is lower than 15℃, it will hibernate when it is higher than 33℃, and it may freeze or heat to death when it is lower than 5℃ or higher than 40℃. I like to burrow into loose humus soil to inhabit, lay eggs, adjust the humidity in my body and absorb some nutrients for up to 12 hours. Omnivorous food and partial eclipse coexist. Love humidity, fear flooding. Snails have a good appetite when they eat wet food on wet nights. But floods will suffocate snails. Self-sufficiency. As soon as the little snail hatches, it crawls to eat without mother's care. When invaded by the enemy, its head and feet retract into the shell, secreting mucus to seal the mouth of the shell; When the shell is damaged and fails, it can secrete some substances to repair the body and the shell. Have great patience. Snails have amazing viability and strong cold, heat, hunger and drought tolerance. For example, constant temperature farming. The temperature is constant between 25 ~ 28℃, and the growth, development and reproduction are vigorous. Snails have a wide range of feeding habits, mainly vegetables, weeds and melon skin; Leaves, stems, buds, flowers and juicy fruits of crops; Eat all kinds of grass and green tree feed, juicy feed, bran feed and cake feed. Four stages of snails 1) Incubation period: refers to the period from laying eggs to hatching out shells. 2) Juvenile snail stage: Juvenile snail refers to the snail stage within 30 days after hatching. 3) Oncomelania stage: When the young snail reaches the age of 1 ~ 6 months, this 5-month-old snail is called Oncomelania stage. This is a period between young snails and seed snails. Snails are at this stage of growth and development (individual expansion) and reproductive growth (growth and development of sexual organs). 4) Oncomelania period: Oncomelania snails that have grown for more than 6 months. The medicinal value of snails has long been recorded in Compendium of Materia Medica. Modern Chinese medicine also recognizes that snails have the functions of clearing away heat and toxic materials, reducing swelling, treating and quenching thirst. It can be used for adjuvant treatment of diabetes, hypertension, hyperlipidemia, tracheitis, prostatitis, malignant ulcer and cancer. Efficacy; Treatment of swelling and pain, anal contraction, diuresis, application and indications: treatment of swelling and toxin; Start treating sores; Treat diseases; Treat toothache; Recently, higher nervous activity and Neurophysiology of Russian Academy of Sciences are trying to treat Parkinson's disease with the nerve tissue of mollusks such as snails. Parkinson's disease is caused by the gradual degeneration of substantia nigra cells in the brain and the cessation of dopamine secretion. Its main symptoms are muscle stiffness and trembling hands and feet. It is found that mammals have weak rejection ability to mollusk tissues, and the researchers implanted snail nerve tissue into the brain of mice, which can be compatible for more than 6 months. After further improving the technology, Russian experts have been able to fuse the nerve tissue of snails with the brain tissue of mice with Parkinson's disease, and gradually restore the brain function of damaged mice. According to the above results, Russian experts will use the nerve tissue of mollusks to carry out experimental clinical treatment on volunteers with Parkinson's disease in the next stage of research. Medical Description Alias: Snail, Niu Lin and Guanniu Source: Eulota similaris Ferussac, a large snail, which is used as medicine in whole or live individuals. Capture in summer and autumn, blanch in water and dry in the sun; If you use fresh products, grab them when you use them. Nature and taste: salty and cold. A little poisonous. Indications: clearing away heat and toxic materials and inducing diuresis. Used for carbuncle, furuncle, hemorrhoid, leakage and dysuria. Usage and dosage: 0.5 ~ 1 RMB, ground into powder or taken as pills. Appropriate amount for external use, ground or mashed with fresh products, and applied to the affected area. The edible value of snails Snails, shark's fin, scallops and abalone rank as four famous dishes in the world, which contain more than 20 kinds of amino acids, 10 trace elements and rich snail enzymes and SOD, among which the content of protein is higher than that of soft-shelled turtle, pork and eggs by 1, 10, 3 and 6 percentage points respectively, while the fat content is only soft-shelled turtle and pork. The selenium content per gram of snail meat is 0.45 micrograms, which is 4.5 times that of tea. From the perspective of market capacity, snail food conforms to the new trend of naturalization, game, nutrition and health care, and has a broad market at home and abroad. At present, the annual demand for snail products in the international market is about 400,000 tons, and the United States alone needs to import 3 billion dollars of snails every year. The market price is also high. The ex-factory price of frozen snail meat in new york is equivalent to RMB 362.39/kg, and the price of a dish made of six snails is as high as 18 USD. The price of live snails in France and Spain is equivalent to RMB116.11yuan. The price of the canned white jade snail we signed for export also reached 9000 ~ 14000 USD per ton. White jade snail is a new breed cultivated in batches in China. It is tender, white and big, and it will be more competitive in the international market. In recent years, new products such as health food series, biochemical drugs series, compound nutritious drinks series, cosmetics series, canned game series and frozen meat series have been introduced. It has been successfully developed in China, and several snail drugs for treating tracheitis, prostatitis and other diseases are about to be mass-produced. Snail secretion can also be used to refine and process natural nutritional cream. Snail is a kind of terrestrial mollusk, which has high edible, medicinal and health care values. Its edible and medicinal history has been more than 2000 years. In foreign countries, snail is one of the seven world game, ranking first among the four famous international dishes (snail, abalone, scallop and shark's fin). In France, it has the reputation of "French cuisine". In Europe and America, there are almost no snails to celebrate Christmas. In recent years, snail eating fever has risen quietly in China's coastal open cities, and snails on the market will be out of stock every holiday. Comrade Deng Xiaoping tasted snail food before his death. He praised: "Snail food fills a gap in China and should be well developed." Snails enjoy the reputation of "soft gold" in the world. Its meat is tender, delicious and nutritious. According to the determination, every 500g of snail meat contains 90g of protein and various nutrients needed by human body, such as amino acids, vitamins, calcium, iron, copper and phosphorus. It is a food with high protein and low fat. Snails are cold and salty. It has the effects of clearing away heat, relieving swelling, detoxicating, promoting diuresis, relieving asthma and softening hard mass. It has a certain curative effect on diabetes, cough, pharyngitis, mumps, scrofula, sore pain, hemorrhoids, centipede bites and other diseases, and is praised as a delicious food and a good health care product by consumers. Snails are afraid of salt, and because of dialysis, water in the body will penetrate from the body with low salt content to the body with high salt content. Salt will make snails lose water and dehydrate to death. According to scientists' calculations, the fastest crawling speed of snails is about 12.2 meters per hour. Nowadays, people often use snail crawling as a metaphor for slow speed. The most deadly natural enemy of snails is fireflies (larvae eat snails and adults lay eggs in snails). There are snails, beetles and mice. Some natural enemies that are not easy to find are parasitic bees and acaroid mites. Acaroid mites should be what you call white bugs. Many people live in groups and feed on the body fluids and epidermal mantle of snails or slugs, which will not cause much harm in a short time. If they get bigger, they will be pointed out to snails. Take out the bones after getting up in the morning, often to reduce the parasitism of acaroid mites! The only reason for this is that your breeding environment is not good! Even if there is no cleaning residue and excrement, or the humidity and temperature are too high. The technical point of snail culture is 1. Temperature 16 ~ 40℃, 25℃ is the best, generally high or low. Heating must be carried out by earthworm fire path, and it should be prepared all year round, especially in late spring and early autumn, to prevent sudden flooding. Conditional heating is the best, and it is not necessary to use a stove for heating. 2. humidity. The soil surface humidity of the feeding soil should be kept at 25% ~ 35%, and the relative humidity of the air should be 85% ~ 90% to make it moist, and the top should be covered with plastic sheets for moisture control and moisturizing. 3. In order to prevent dry air and cold air from blowing in directly, double doors, cloth hanging and wind deflector should be adopted for import. 4. Resolutely control the malodorous gas entering the breeding ground. 5. Feeding soil must be controlled at pH 6.5 ~ 7.5, and it is forbidden to use polluted sand containing pesticides and chemicals. 6. The culture container must have good water permeability and air permeability. 7. Don't be exposed to bright light when not working, preferably in the dark. Lighting with 15W red bulb at night can stimulate spawning. 8. Hatching of eggs. The key to the success or failure of snail farming lies in the hatching of eggs. Indoor temperature is controlled at 20~25℃, air humidity is controlled at 90% ~ 95%, and soil surface humidity is controlled at 25% ~ 30%. Improve the method of egg collection and incubation, and adopt the 60-day snail cultivation method. This method can greatly improve the reproductive efficiency of snails, and the general hatching rate is above 95%. 9. The feeding of young snails is related to the success or failure of the rapid development of snail quantity and output, and special attention should be paid to the control of temperature and humidity. Generally, the temperature should be controlled between 25 ~ 30℃, the water content of the soil is 30% ~ 35%, and the relative humidity of the air is 80% ~ 90%. Eat more fresh and juicy feed, supplemented by calcium supplements. 10. 1~3-month-old snail culture ponds should be humidified and do not splash water. Spray with a sprayer, preferably warm water. 1 1. Remove dead snails in time. 12. It's best to kill two birds with one stone when earthworms and snails are mixed. 13. Prevent the invasion of natural enemies and kill rats and ants. Regular spraying with11000 trichlorfon solution can effectively kill the largest natural enemy mite of Oncomelania hupensis, and regularly disinfect the snail breeding ground with peracetic acid diluent to kill pathogenic microorganisms. 14. The lowest cost and best feed formula: 50% rice bran, 40% shells, 8% yeast powder and 2% others. There are many kinds of snails, about 25,000 species, all over the world, including thousands in China alone.
