1, juvenile snail stage
Young snails refer to snails within 1 month after hatching from eggs. The young snail stage is characterized by its weak adaptability to the external environment, but its growth rate is very fast, which requires fresh, juicy and nutritious food.
2. Growth snail stage
Snails 2-4 months old are generally called growing snails. After entering the growth stage, the development of the snail's jaw, teeth and tongue tends to be complete, and its feeding ability is strong. The daily consumption is 5% of its body weight, and its metabolism is vigorous and its growth rate is fast. Their weight increased from 5 grams to 30 grams (white jade snail), and their gonads gradually matured.
3. Snail stage
From 5 months old to natural aging and death, it is the snail stage. At this stage, snail gonads mature, reproductive organs begin to develop, glands begin to secrete, and gradually enter a period of sexual exuberance, and sexual excitement often occurs. At the same time, snout, jaw, tooth tongue and salivary gland have developed, which has a mixed diet and a large appetite and has entered the breeding period.

Feeding and management
Generally divided into outdoor open and indoor closed two kinds.
Outdoor opening includes ditch type, shed type and courtyard type. To make it grow and breed in the protected area, similar to natural conditions. Indoor closed culture can use plastic pots, pottery pots, wooden boxes, cement pools, cylinders, barrels, cans and so on. Covered with gauze, sealed with wet cloth and film to keep warm and moist and prevent rodents.
Indoor closed breeding is convenient for the adjustment of temperature and humidity, and with sufficient feed, it can not only relieve the hibernation of snails, but also achieve the purpose of breeding in winter. Indoor culture is best to use plastic film to seal the surroundings and keep the temperature and humidity.
Feeding method
1 month-old young snails should be fed with fresh and tender leaves, and the concentrated feed should be boiled and softened on the leaves, once a day 1 time. The optimum temperature should be controlled at 25℃ ~ 30℃, and the temperature difference between day and night should not be large. Don't spray young snails directly when spraying water. In addition to green materials, more concentrated materials, trace elements and additives should be added to raise snails.
