Abstract:

Pomacea canaliculate is a global invasion aquatic animal and caused serious harm in some countries and regions. In the early 1980s Pomacea canaliculated was introduced to China, and then rapidly spread to southern provinces by cultivating. It has become the malignant aquatic animal of harm paddy and the other aquatic plant. In this paper, we investigated the history of Pomacea canaliculate introduction and spread, the invasion region and prevention situation in China based on literature research. The result indicated that the introduction and cultivation in aquaculture industry were the primary reason of invasion and spread of Pomacea canaliculate. Because of lack of scientific manage, Pomacea canaliculate has caused huge economic loss and destroyed the local ecosystem in most regions of southern China. This shows the weakness to manage the exotic species in our country, and it is very urgent to manage the invasive species.
