Breeding prospects and techniques of Baiyu snail

Recently, some farmers have written to inquire about the breeding prospects and techniques of Baiyu snails, and now introduce the relevant situation of Baiyu snail breeding.

I. the breeding prospect of Baiyu snail

The prospect of raising white jade snails is very good. Eating snails is a human delicacy, which is favored by people at all times and all over the world. It is often said that French fried snails, braised snails, roasted snails and so on are all delicacies in the world. Snail meat is clear, delicate, nutritious and delicious. The protein content of snail meat is higher than that of chicken, duck, pig, beef and mutton. It contains almost no cholesterol and low fat content. Snail protein is rich in 20 kinds of essential amino acids, as well as a variety of other nutrients, such as calcium, phosphorus, iron, thiamine, glucose, liver sugar and other carbohydrates. Because of its high comprehensive utilization value, high protein, low fat and a variety of nutrients, Baiyu snail has become a delicacy on people's dinner table, and the market of Baiyu snail is smooth, and it is a pillar industry for export to earn foreign exchange.

2. Feeding techniques of Baiyu snails

1. Living environment

Like other snails, Baiyu snails like to live in a dark, damp, loose humus environment, sleeping during the day and out at night, afraid of light and heat, and most afraid of direct sunlight. Extremely sensitive to the environment, when the humidity and temperature are not suitable, the snail will shrink back into the shell and secrete mucus to form a protective film, seal the shell mouth, in order to overcome the interference of adverse environment. When the environment is suitable, the protective film will automatically dissolve and resume its activity. Therefore, attention should be paid to the influence of temperature and humidity in the process of culture.

The suitable temperature is 16 ℃ 30 ℃, the humidity is 60% mi 85%, the soil moisture is about 40%, and the soil moisture is 5 ℃ 7. When the temperature is lower than 15 ℃ and higher than 35 ℃, dormancy and stop growth and reproduction.

2. The feeding habits of Baiyu snail

All kinds of green plants and bran can be used as food. Generally in spring, cabbage, green vegetables, lettuce and other broad-leaved plants can be fed; in summer, a large number of sugarcane, sunflower leaves, a variety of melon and fruit peel dregs can be fed; autumn temperature is low, food intake is reduced, you can feed some vegetable leaves, potato chips, and so on. White jade snails do not eat grass or weeds, but refuse to eat onions, leeks and garlic with irritating taste.

3. Reproduction

White jade snails are hermaphroditic and allogeneic. Artificial breeding can reproduce all the year round as long as the temperature and humidity are suitable. It usually takes 6 months from hatching to sexual maturation. After mating and fertilisation, eggs can be laid within 20 days after mating and the eggs are laid in the cave. The egg is the size of mung bean, wrapped in a white shining membrane, each spawning 100 Mu 200 eggs, 8 MUE 15 days can hatch the young, the life span is generally 5 Mel 6 years.

4. Feeding and management

(1) feeding mode: according to the breeding site and equipment, it can be divided into two types: outdoor open type and indoor closed type. Outdoor earth trenches or greenhouses can be dug. If ditches are adopted, the earth ditches should be built in the leeward direction. The soil ditches should be dug down to 70 cm, 2 meters wide, and the length should be determined according to the amount of feeding. The ditch should be high on one side and low on the other, with a slight slope, and covered with film and bamboo curtains to prevent escape and prevent the injury of frogs, birds and other natural enemies. Indoor aquaculture can use soil pots, plastic boxes, wooden boxes, cement ponds, etc., sealed with sand cover, wet cloth, film, etc., moisturizing and rodent prevention.

(2) preparation of feeding soil: the feeding soil is required to be moist, loose and fertile, so it is best to choose uncontaminated pastoral soil and yellow sand, and then add a small amount of stone powder to mix, sterilize and screen for 5 days after exposure to the sun. The earthwork ratio is: 30% of fine soil, 30% of sand, 20% of yellow sand, 15% of cinder ash, 5% of stone powder, and the humidity is about 40% after adding water. The soil thickness in the basin is divided into: cochlea 10 cm, growth cochlea 7 cm, baby cochlea 3 cm. The breeding soil was changed once in 1-2 months.

(3) feeding method. The baby cochlea should be fed with fresh vegetable leaves and some refined fodder, the temperature should not be lower than 20 ℃, the temperature should be controlled at 25 ℃, do not have too much temperature change, and do not spray the baby directly when spraying water. The food containing calcium in the feed must not be lacking, and it should be transferred to the adult cochlea culture basin after 1 month, and the stocking density should be from dense to sparse with the continuous growth of the individual. 500 birds per square meter were stocked, compared with 250 birds per 200m before harvest. 100 animals can be stocked in a 60 × 30 × 25 cm feeding box. After 6 months, the shell height is 4 cm and the body weight is 40 grams.
