The reason why the eggs of Ampullaria gigantea are broken is to prevent the harm of Ampullaria gigantea to crops when it grows up. Pomacea canaliculata is an alien invasive organism, which is different from native snails in China. It will climb plants, feed on the tender stems and buds of plants, and lay eggs on plants, growing in dry places, causing damage to crops.

Pomacea canaliculata is also not suitable for eating. This kind of food is meaty and tastes bad. Because a giant individual can carry thousands of parasites, people abandon it.

Breeding mode of Ampullaria canaliculata

Pomacea canaliculata is bisexual. In mid-March, they began to lay eggs in Xishuangbanna, China, and reached sexual maturity in only 2-3 months. After fertilization in vivo, the male and female snails twisted together to mate for 2-5 hours.

If it is disturbed by touch during mating, it will stop immediately. Through feeding observation, it is found that female snails often lay eggs at night, climb out of the water when laying eggs, and lay scarlet egg pieces on the pond wall or plants and wooden stakes on the water surface, and the ovulation time is as long as 1-2 hours.

Egg pieces are attached to the object, and each egg piece contains 190-505 eggs. The longest egg piece can reach 8.8 cm and weigh 2.8 g.. When the temperature is in the range of 20-25℃, the incubation time of egg mass is 17-25 days; When the temperature is in the range of 27-32℃, the incubation time of egg mass is 8- 16 days.
