Snails often inhabit lakes, ponds, rice fields and mild rivers. They are warm in winter and cool in summer, with soft soil and rich food.
The optimum water temperature for its growth is about 20 ~ 25℃. When the water temperature reaches 15℃ and above 30℃, stop feeding.
When the temperature is lower than 10℃, it will go into hibernation, and when the water temperature returns to above 15℃, it will return to the cave to eat.
The artificial culture of snails can be carried out in special ponds, natural paddy fields, swamps and ditches, or mixed with fish. However, aquaculture water is required to be non-toxic, harmless and pollution-free. If the paddy field is used for farming, pesticides cannot be used, and farming and harrowing cannot be carried out, barbed wire or plastic filter screens should be installed at the inlet and outlet for control.

Nutritional value of screws
First of all, snails are rich in calcium. Every100g of snail contains about156mg of calcium, which is obviously higher than other foods. Therefore, children, menopausal women and the elderly in the growth and development stage eat some snails, which can play a role in supplementing calcium.
Followed by minerals, snails are rich in minerals, including phosphorus, selenium, iron, potassium, magnesium and copper. For example, selenium is related to people's longevity, and iron is related to improving anemia. The human body can't synthesize these minerals, so we should eat snails to get the right amount of minerals.
Protein: Again, there are about 7.5 grams of protein per 100 grams of snails. Although the content is not high, there are many kinds of amino acids, especially essential amino acids. Therefore, eating snails can supplement a variety of amino acids for human body.
