The food habits of the snail is relatively mixed, wild snails in nature mainly eat aquatic plants tender stems and leaves, algae, organic debris, bacteria, etc., but also eat plankton, preferring to be active and feeding at night.

Farmed snails: If the snails are artificially raised, they mainly eat a variety of leaves, fruits and vegetables, and the feet of various animals. Feeding is best timed and quantitative, but also to ensure that the water quality is fresh, clean and clean water, so as to ensure better development of snails.

The snail scientific name China round snail (Cipangopaludina chinensis Gray), in our country all over the freshwater lakes, reservoirs, rice paddies, ponds and ditches are widely distributed. Because of its meat tender and flavorful, nutritious, and has a heat quenching, thirst, eyesight and other therapeutic effects, has become one of the people's favorite aquatic products, especially in the south it as a delicacy on the table.

The main feeding organ of the snail is the tooth and tongue, which is used to scrape the bottom of the water and epiphytic food. In the natural environment, the snail mainly eats aquatic plants, algae, bacteria and organic debris, but also filter-feeding zooplankton, and prefer night activities and feeding.

The snail starts to move and feed at a water temperature of about 15 degrees Celsius, and the optimal temperature for growth is 20 to 28 degrees Celsius, and at 30 degrees Celsius or more, the snail will shrink its flesh into its shell and cluster in the shade or dive into the soil to avoid the heat, and the snail will die when the water temperature is more than 40 degrees Celsius.

The snail is highly adaptable to drought and cold, and hibernates in mud holes when the water temperature is below 8°C. The snail will come out of its holes and feed only when the water temperature rises to about 15°C in the spring of the following year. The snail is very sensitive to the dissolved oxygen in the water, when the dissolved oxygen in the water drops to 3.5mg/L, they are not feeding; 1.5mg/L, start to die.
