The Fukushou snail, also known as the big bottle snail, apple snail, is native to the Amazon River basin in South America.

It was introduced into China in 1981 as an edible snail, and has become a harmful invasive alien species because of its strong adaptability and rapid reproduction.

Harmful effects of the Fukushu snail: Because the Fukushu snail is a very large eater and can eat very rough plants, it can also scrape and eat algae, and its feces can pollute water bodies.

The damage it causes to rice production obviously greatly exceeds its value as a delicacy.

In addition to threatening aquatic shellfish, aquatic plants and disrupting the composition of the food chain in the invasion site, the fusilier snail is also an intermediate host for the coiled spiny mouth sucker and the Guangzhou tubular round nematode.
