1. Temperature is an important factor affecting its growth activity. It has the characteristics of being warm and avoiding cold and hot. This is determined by genetic factors. Because snails are cold-blooded animals, that is, cold-blooded animals, their body temperature changes with changes in environmental temperature, so temperature is particularly important for the growth and reproduction of snails. The most basic temperature requirement for the growth and activity of snails is 15-39 degrees. The optimal temperature is 25-35 degrees. When the temperature drops to 8 degrees, it will gradually enter a dormant state. There is a risk of freezing to death below 0 degrees. When the temperature rises to 40 degrees, it will cause aestivation.

2. The living habits of snails depend on the appropriate temperature and humidity. This is because the daily activities of snails rely on their own secretion of mucus with a high water content to keep the body moist. On the other hand, because snails rely on their mantles to breathe air and cannot live completely immersed in water, snails develop a tendency to love tides. immersion habit.

3. Strong light stimulation is detrimental to the growth of snails. Snails are mainly active at night, are afraid of direct sunlight during the day, and like to live in dark and humid environments. Snails have very poor and abnormal vision. They can see closer under strong light and can only see objects within 6 centimeters. However, they can see farther under weak light and can see objects within 20 centimeters.

4. Under normal circumstances, because snails are afraid of direct sunlight, and the temperature difference at night is small, the air humidity is high, and the light is dark, it is not suitable to lose water in the snail's body, so it usually moves and feeds at night. The activity pattern starts around 6 p.m., reaches its peak between 8 and 12 p.m., and gradually decreases after 12 p.m., until it basically stops completely around 8 a.m. the next morning and begins to rest.

5. During the growth and development process, snails need to drill into the soil. First, they absorb humus, organic matter, calcium and other nutrients from the soil; second, they adjust the humidity; third, they resist enemies; fourth, they lay eggs. .

6. Dormancy is the habit of snails to resist adversity, protect themselves, and maintain life. When snails encounter unfavorable conditions such as high or low temperatures, lack of food, or water shortage, they will automatically secrete mucus to form a membrane and seal the mouth of the shell until the adversity is relieved, then they will gradually wake up, break out of the membrane, and continue to move. The dormant period of snails can last up to 6 months, which means that snails can sleep for 6 months without eating and will not die.

7. Snails are omnivores and generally feed on roots, stems, leaves, flowers, fruits, etc. of green plants, such as lettuce leaves, cabbage leaves, pumpkin leaves, loofah leaves, and bitter apples. They like vegetables, sweet potatoes, carrots, and various fruits, but they do not like to eat irritating plants, such as leeks, garlic, onions, peppers, and salty foods. In addition, they also eat some sand and soil because the soil contains humus. Young snails mostly feed on humus and fully decomposed plant leaves.

Snails like to live in dark, moist, humus-rich and loose soil. It is afraid of direct sunlight. It lives in dark and hidden places during the day and only comes out at night to look for food.

The optimal temperature for it to live is 18 to 30 degrees. At this temperature, it has a strong appetite and grows the fastest. The air humidity of 60% to 90% is beneficial to its growth. The pH value of the breeding soil in which it is located is 5~7 and the soil humidity is 40%.

Snails are vegetarian animals and like to eat cabbage, lettuce, green vegetables, cabbage, carrots, sugar cane and the skins of melons and fruits, but they do not eat grass plants, onions, garlic, ginger, peppers, leeks, Shepherd's purse and other pungent vegetables and plants with peculiar smell.

The living habits of snails

1. It likes a dark, humid and hidden environment, lying in bed during the day and emerging at night. Very sensitive to strong light stimulation.

2. It likes to dig into loose humus soil to inhabit, lay eggs, adjust body humidity and absorb some nutrients, which can last up to 12 hours.

3. Omnivory and partiality coexist.

4. Likes moisture and is afraid of flooding. The snail's appetite is active during humid nights and when fed wet food. But flooding can suffocate snails.

5. Self-feeding survivability. As soon as the baby snails hatch, they will crawl and feed without maternal care.

When infested by enemies, its head and feet retract into the shell and secrete mucus to seal the mouth of the shell; when the shell is damaged and disabled, it secretes certain substances to repair the body and shell.

6. Have strong patience. Snails have amazing survivability and are very tolerant of cold, heat, hunger, and drought.

7. Like constant temperature breeding. The temperature is constant between 25 and 28°C, and growth, development and reproduction are vigorous.

8. In the process of breeding snails, it was also discovered that snails have very terrifying characteristics. The first is fear of high temperature, the second is fear of low temperature, the third is fear of alarm, the fourth is fear of dryness, the fifth is fear of water immersion, the sixth is fear of stimulation, the seventh is fear of suffocation, the eighth is fear of pollution, the ninth is fear of spicy food, and the tenth is fear of insect infestation.

Snails’ sense of humidity Although snails are shellfish that live on land, most of them like a humid environment and are very sensitive to the humidity of the air. Humidity in the air can affect the stretching of the snail's skin and muscles. Wet nights, especially after rain, are when snails are most active.

There are many snails that appear before it rains. When we see a large number of snails on trees, leaves or grass, we can conclude that it is about to rain. There is some truth to why some people regard snails as barometers. Experiments have proven that snails are not only extremely sensitive to humidity in the open air, but also have an extremely sensitive sense of humidity even if they are placed indoors and covered in a glass cover. Some species that are particularly accustomed to living in humid places will find an environment suitable for them if placed in a dry environment.

In addition, snails have many "special instincts".

Darwin once recorded an interesting story. Someone told him that two snails were found in a very deserted small garden without enough food. One of them was sick and had difficulty moving. At this time, the stronger one immediately left his companion and quickly crossed the height. The wall went to another garden where food was plentiful. Soon it returned to its companion from another garden, and immediately went with its companion to the garden where there was abundant food. This record may indicate that it has a special instinct!

The snail can return to its original hiding place every day. Someone once made this observation: 7 snails were found under a stone slab, and they were marked with their own colors. Around 10pm, three were missing. When I looked at it the next morning, I found that they were all back under the stone slab. At 10 o'clock the next night, 5 more people had gone out, and 2 of them were found on the nearby grass. By the next morning, 6 of the 7 snails were safely back under the stone slab.

The snail’s habit of returning home is sometimes particularly prominent. For example, there is a kind of snail that hates the smell of charcoal and will go around the charcoal field to find food. After eating the food, it will return to its original place of residence. Although it can easily find a more suitable new home where there is food, it still has to crawl back around the char piles it hates.

Snails are very resilient and can tolerate cold, heat, drought and hunger. When it is very cold, the snail's activity stops, its heart beats very slowly, and it enters hibernation. Generally after autumn, when the weather gradually changes and plant food decreases, snails crawl under rocks, caves in ancient walls, tree holes, stone crevices, or burrow underground to live in seclusion. At that time, its body has completely shrunk into the shell, and it secretes a white membrane with its feet to block the mouth of the shell, so that it can survive the winter safely. Sometimes many snails gather together to hibernate.

In very hot areas, snails undergo aestivation to survive the summer. Many types of snails are very resistant to heat. For example, in Africa, some places are so hot that there are even few plants, but there are snails living there. In order to protect themselves and make themselves highly resistant to strong light and heat, snails have two ways of adapting: one is to make the color of their shells white, which is the same as when we wear white clothes in summer, because White things absorb less light and heat; the other is to thicken the shell so that light and heat cannot easily penetrate inside.

Snails can live for a long time without food at all. For example, on March 25, 1846, scientists plucked two snails from Egypt, returned them to a museum in England, glued them to fixed plates, and stored them in the herbarium. But when they were taken out for study on March 15, 1850, it was discovered that one of them had a newly formed mucus membrane at the mouth of the shell.

The scientist felt strange, so he took it off the board and put it in warm water. Soon its body came out of the shell. I ate some cabbage leaves the next day, and after 1-2 months, the damage suffered when I took it off the board had recovered. For nearly four years, it received neither food nor water, but it was able to survive very well. There are many examples that show that snails can live for 4-6 years in this situation. This is really an amazing thing. I am afraid that except for some insects, few other animals have this ability.

7. Like constant temperature breeding. The temperature is constant between 25 and 28°C, and growth, development and reproduction are vigorous.

2. Feeding methods

1. The equipment is simple. There is a breeding room with a certain temperature and humidity. It can be raised in wooden boxes, basins, tanks, greenhouses, or three-dimensional shelves.

2． The feeding method is easy to learn and does not take up a lot of labor. You can use your spare time to feed and mist water once every afternoon or evening.

3. A wide range of feeds, such as weeds, vegetable leaves, leaves, plant roots, peels, etc., can be used as feed. You can also add a small amount of cornmeal, bran, soybean meal and other feeds.

What do snails eat?

Generally, they feed cabbage, green vegetables, lettuce and other plants in spring; in summer, they can feed various melon and fruit peel residues, sugar cane, sunflower leaves, etc.; in autumn and winter, they feed vegetable leaves, potatoes Slices, carrots, etc. White jade snails do not eat grass, weeds, and refuse to eat onions, ginger, garlic, leeks, mustard and other smelly foods. Fruits and tubers must be cut into thin strips or thin slices before feeding, and pay attention to the diversity of food. To prevent partial eclipse. In order to speed up growth and increase spawning rate, it is best to add mixed concentrates such as crushed wheat bran, rice bran, tofu residue, yeast powder, soybean meal, fish meal, bone meal, shell powder or stone powder to the feed. Commonly used feeds Formula: 50% rice bran and bran, 40% shell powder, 8% yeast powder. Others (fish meal, soybean meal, flour) and 2% trace elements and special additives. The amount of concentrate added accounts for 10% to 15% of the total feed. %. Feeding should be done around 6 o'clock in the evening. Feeding activity reaches its peak between 20 and 24 o'clock. Feeding should be stopped at 6 o'clock the next day.

White jade snails like to live in a dark, moist, loose and humus-rich environment. It is nocturnal, most afraid of direct sunlight, and is sensitive to the environment. The most suitable environment is: temperature 16~30℃ (the fastest growth occurs at 23~30℃); air humidity 60%~90%; breeding soil humidity 40% Around; the pH is 5 to 7. When the temperature is lower than 15 ℃ and higher than 33 ℃, it will go dormant. If it is lower than 5 ℃ or higher than 40 ℃, it may freeze to death or heat to death.

Snails:

Snails belong to the order Stalkeye, the phylum Mollusca, the class Gastropoda, and the family Snailidae.

1. Appearance characteristics of snails

The shell is low conical, right-handed or left-handed. The head is prominent, with two pairs of antennae, and eyes on the top of the latter pair. There are flat and wide abdominal feet on the ventral surface.

2. Living habits of snails

1. It likes a dark, humid and secluded environment, stays in day and night, and is very sensitive to strong light stimulation.

2. It likes to burrow into loose humus soil to inhabit, lay eggs, adjust body humidity and absorb some nutrients, which can last up to 12 hours.

3. Omnivory and partiality coexist.

4. Likes moisture and is afraid of flooding. The snail's appetite is active during humid nights and when fed wet food. But flooding can suffocate snails.

5. Self-feeding survivability. As soon as the baby snails hatch, they will crawl and feed without maternal care.

6. Have strong patience. Snails have amazing survivability and are very tolerant of cold, heat, hunger, and drought.

7. Like constant temperature breeding. The temperature is constant between 25 and 28°C, and growth, development and reproduction are vigorous.

3. Reproductive characteristics of snails

1. Snails are hermaphroditic, mate, and both males and females lay eggs. The snail itself acts as both father and mother. The two snails cooperate with each other, and the two snails repeatedly stimulate each other's reproductive holes with their penises. After intense thrusting movements, the penises of both sides insert into the other's vagina and ejaculate. After 10 days of conception, both parties can lay eggs, and 8 days later the eggs can hatch into small snails.

2. Mating takes a long time, spawning is slow and difficult. The mating time of snails in estrus lasts for 2 to 3 hours each time, and some last for more than 6 hours. Snails can lay 2 eggs per minute, and each egg laying time lasts for 1 to 2 hours, and some eggs last for more than 3 hours. During the process of laying eggs, snails often die due to poor nutrition, collapse and dystocia. Some deaths due to dystocia account for about 30% of the total number of snails.

3. High reproduction rate. Each snail can lay eggs 6 to 7 times a year, with an average of 200 eggs each time. A snail weighing 35 grams can lay 120 eggs each time, a snail weighing 40-50 grams can lay 150-180 eggs each time, and a snail weighing 60-100 grams can lay 300-400 eggs each time. grain.

4. The reproduction of snails is not restricted by age. Under the same suitable reproductive conditions, the larger the snail, the more eggs it will lay.

5. Short life span. The life span of snails is generally 5 to 6 years. Unsuitable living conditions will accelerate the death of snails and shorten their lifespan.

6. Three are slow, two are fast, one is difficult and one is multiple. The three slownesses are slow movement, slow mating and slow egg laying; the second fastness is fast growth and shell shrinkage; the first difficulty and the plurality are difficulty in laying eggs and the number of eggs laid.
