In the past, they were mainly obtained by artificial field collection. With the large-scale prevention and control work, it is increasingly difficult to collect snails. Therefore, it is necessary to artificially raise and breed snails. At present, most indoor breeding methods use porcelain plates of different specifications, covered with thin sponges and coarse straw paper, or mud bowls covered with soil. These breeding methods require regular feeding, adding water to keep moisture, and regular disinfection and cleaning of containers. At the same time, due to weather factors, temperature and humidity are difficult to control. The current methods of raising snails are prone to high snail mortality rates, time-consuming and labor-intensive operations, and cannot guarantee the demand for snails in scientific research, experiments, and teaching.
