Snails are hermaphrodites, allogeneic fertilized, oviparous and fertile. The development of the snail breeding industry depends on the quality of seed production. The quality of snails directly affects the reproduction rate and the number of snails. When introduced, it is necessary to select and select snails that are robust, plump, lively, mucus-rich, flexible, shell-integrated, non-disabled, bright and clean, and well-defined stripes with a few growing edges, high reproduction rates, and strong adaptability. For example, white jade snails, with a body weight of 45g or more, have a clean white belly (if it is dark yellow, it is not suitable for breeding), and snails with more than 5 months are good, and they are changed every year. This kind of snail has more mature maturity and spawning time is concentrated. The young snails hatched consistently and spawned more. Therefore, we must seize the main technical links throughout the entire production phase so that the seedlings can be cultivated smoothly and produce a batch of snails that are neat and robust.
