cannot

The white jade snail is of great economic value. Its whole body is a treasure and can be used in many ways. Therefore, the market demand is very large now, and it is also a very promising breeding prospect. It likes to eat green plants, rice bran, and wheat bran. In spring, it is often fed with cabbage, green vegetables, and various leafy vegetables. In summer, it can be fed with sugarcane, watermelon, melon peel, and fruits such as apples. Feed with high water content can ensure the water needed in summer. In autumn, the temperature drops and it eats much less. It is mainly fed with vegetable leaves and red limbs. This kind of snail generally does not eat grass or vegetables with pungent taste.

Reproduction method: Oviparous. White Jade Snail is hermaphroditic and mates with different sexes. It can reproduce all year round in artificial breeding as long as the temperature and humidity are suitable. It usually takes 6 months from hatching to sexual maturity. It can lay eggs 15 to 20 days after mating and fertilization. The eggs are laid in caves. The eggs are the size of mung beans and are covered with a layer of shiny white membrane. Each time, 100 to 200 eggs are laid. Baby snails can be hatched in 8 to 15 days. The life span is generally 5 to 6 years.

Habits: They like to live in a dark, humid, loose and humus-rich environment. They hide during the day and come out at night. They are afraid of light and heat, and are most afraid of direct sunlight. They are extremely sensitive to the environment. When the humidity and temperature are not suitable, the snail will retract its body into the shell and secrete mucus to form a protective film to seal the shell mouth to overcome the interference of the adverse environment. When the environment is suitable, the protective film will automatically dissolve and resume activities. Therefore, during the breeding process, attention should be paid to the influence of temperature and humidity. The suitable temperature is 16℃~30℃, humidity is 60%~85%, soil humidity is about 40%, and pH is 5~7. When the temperature is below 15℃ and above 35℃, it will hibernate and stop growing and reproducing.

Physical characteristics

Diet: All kinds of green plants and bran can be used as food for white jade snails. Generally, they are fed with broad-leaved plants such as cabbage, green vegetables, and lettuce in spring; in summer, they can be fed with large amounts of sugar cane, sunflower leaves, and various melon and fruit peels; in autumn, when the temperature is low and the appetite decreases, they can be fed with some vegetable leaves and potato chips. White jade snails do not eat grass or weeds, and refuse to eat onions, leeks, and garlic, which have pungent tastes.

4. Does anyone know what kind of grass should be planted to breed white jade snails? Where can I buy that kind of grass seeds? Thank you for your answer!!!

1. The breeding prospects of white jade snail

The prospect of breeding white jade snails is very good. Edible snails are a delicacy in the world and are favored by people all over the world. People often say that French fried snails, red stewed snails, roasted snails, etc. are all world delicacies. The meat of snails is white, tender, nutritious and delicious. The protein content of its meat is higher than that of chicken, duck, pork, beef and mutton. It contains almost no cholesterol and has a very low fat content. Snail protein is rich in essential amino acids for the human body, with 20 kinds of species. In addition, it also contains a variety of other nutrients, such as carbohydrates such as calcium, phosphorus, iron, thiamine, glucose, and glycogen. Because white jade snails have high comprehensive utilization value, high protein, low fat, and contain a variety of nutrients, they have become a delicious delicacy on people's tables. In addition, white jade snails have smooth sales and are a pillar industry for export and foreign exchange earnings.

2. Breeding technology of white jade snail

1. Living environment

Like other snails, the white jade snail likes to live in a dark, humid, loose and humus-rich environment. It hides during the day and comes out at night. It is afraid of light and heat, and is most afraid of direct sunlight. It is extremely sensitive to the environment. When the humidity and temperature are not suitable, the snail will retract its body into the shell and secrete mucus to form a protective film to seal the shell opening to overcome the interference of the adverse environment. When the environment is suitable, the protective film will automatically dissolve and resume activity. Therefore, attention should be paid to the influence of temperature and humidity during the breeding process.

The suitable temperature is 16-30℃, humidity is 60%-85%, soil moisture is around 40%, and pH is 5-7. When the temperature is below 15℃ and above 35℃, it will go dormant and stop growing and reproducing.

2. Diet of White Jade Snail

Various green plants and bran can be used as food. Generally, they are fed with broad-leaved plants such as cabbage, green vegetables, and lettuce in spring; in summer, they can be fed with large amounts of sugar cane, sunflower leaves, and various melon and fruit peels; in autumn, the temperature is low and the appetite decreases, so they can be fed with some vegetable leaves, potato chips, etc. White Jade Snails do not eat grass or weeds, and refuse to eat onions, leeks, and garlic, which have pungent tastes.

3. Reproduction

The white jade snail is hermaphroditic and mates with different sexes. It can reproduce all year round in artificial breeding as long as the temperature and humidity are suitable. It usually takes 6 months from hatching to sexual maturity. It can lay eggs 15-20 days after mating and fertilization, and lay the eggs in the cave. The eggs are the size of mung beans, covered with a layer of shiny white membrane. Each time, 100-200 eggs are laid, and the young snails can hatch in 8-15 days. The lifespan is generally 5-6 years.

4. Feeding and management

(1) Breeding method: According to the breeding site and equipment, it can be roughly divided into two types: outdoor open type and indoor closed type. For outdoor breeding, ditches can be dug or greenhouses can be built. If trench breeding is adopted, the trench should be built in a sunny place away from the wind, 50-70 cm deep, 2 meters wide, and the length should be determined according to the breeding quantity. The trench should be high on one side and low on the other side, with a slight slope, and covered with film and bamboo curtains to prevent escape and prevent damage from natural enemies such as frogs and birds. For indoor breeding, soil pots, plastic boxes, wooden boxes, cement pools, etc. can be used, and they can be sealed with sand covers, wet cloths, films, etc. to keep moisture and prevent rats.

(2) Preparation of breeding soil: The breeding soil should be moist, loose and fertile. Therefore, it is best to use uncontaminated farmland soil and yellow sand, add a small amount of stone powder and mix, expose to the sun for 3-5 days for disinfection and sieve for use. The soil ratio is: 30% fine soil, 30% sand, 20% yellow sand, 15% coal ash, 5% stone powder. After adding water, the humidity is about 40%, that is, it can be lumped together with a hand and will fall apart with a blow. The thickness of the soil in the pot is divided into: 10 cm for adult snails, 7 cm for growing snails, and 3 cm for young snails. The breeding soil should be replaced once every 1-2 months.

(3) Feeding method. Young snails should be fed some fresh and tender vegetable leaves and some concentrated feed. The temperature should not be lower than 20℃ and should be controlled at 25-30℃. Do not allow for excessive temperature changes. Do not spray water directly on the young snails. Calcium-containing foods should not be lacking in the feed. After one month, they should be transferred to adult snail breeding basins. The stocking density should be changed from dense to sparse as the individuals continue to grow. 400-500 snails should be stocked per square meter, and 200-250 snails should be stocked before harvesting. A 60×30×25 cm breeding box can hold 100 snails. After 5-6 months, they can be harvested when their shells are 4 cm high and weigh 40 grams.
