2. The optimum growth temperature of snails is 20 ~ 25℃. When the temperature is lower than 15℃ or higher than 30℃, snails stop feeding, and when it is lower than 10℃, they hibernate.
3. In artificial feeding, rice bran, vegetable scraps, melon leaves and commercial feed are the main ingredients.
Most snails breed naturally. Artificial culture can be picked up from paddy fields, water bamboo fields and muddy ditches or bought in the market, and then fresh snails with light brown color, thin shell and blunt tail are selected as seed snails.
5, fertile paddy fields, fish and snails mixed culture or water surface stocking red duckweed, green duckweed, water hyacinth and other depressions, can be fed less or not.
6. When fishing snails, it is necessary to selectively catch snails, and more female snails can be harvested in batches.
7. Water quality adjustment. First, the snail pond should be filled with fresh water frequently to adjust the water quality, especially in the breeding season. It is best to keep the pond water flowing, especially in high temperature season, and it is best to adopt running water culture.
8. Snail overwintering management. When the water temperature drops to 8-9℃, snails begin to hibernate. During hibernation, snails drill into the soil with the top of their shells, leaving only a round hole on the soil surface, and bubbles come out from time to time to breathe. Snails don't eat during the wintering period, but the water depth of the culture pond still needs to be kept at 10- 15 cm. Generally, change the water once every 3-4 days to maintain an appropriate oxygen content.
