The discovery of a large number of Eggs of Pomacea canaliculata in Beijing’s Wenyu River Park was reported by CBCGDF Media, which aroused widespread attention from all walks of life. The staff of China Biodiversity Conservation and Green Development Foundation (CBCGDF) research department also rushed to the site for on-site investigation as soon as possible and contacted Beijing Municipal Bureau of Landscape Architecture and Water Affairs Bureau, as well as maintain close communication with experts in related fields.

Dr. Zhou Jingfeng, the Secretary-General of CBCGDF also put forward his own views on some governance suggestions put forward by all parties.

"I agree with relevant experts' judgment and comprehensive management suggestions on the eggs of Pomacea canaliculata in Wenyu River Park. However, I have reservations about the method of ‘adopting waterway blocks to prevent proliferation’ "Dr. Zhou said, “It is recommended to continue to expand the scope of investigation on the upper and lower reaches of Wenyu River and trace the source of the eggs. If similar conditions exist in the upstream and downstream, the measures of blocking the river into sections are of little significance. Second, if we adopt blocking and segmentation, we are worried that it will have certain impacts on the migration of other aquatic organisms and the range of habitats. It is recommended to use it with caution. We oppose the use of medicament to control Pomacea canaliculata, and we have reservations about the poisoning caused by the consumption of Pomacea canaliculata and the impact of Pomacea canaliculata on water bodies.”

Dr. Zhou emphasized that the problem should be assessed in a comprehensive and objective manner from an ecosystem perspective. "The main problem with the consumption of Pomacea canaliculata is not that the species itself is poisonous, but the bacteria and parasites that it accompanies. Therefore, we should look at it differently, scientifically understand the harm of Pomacea canaliculata, and express it objectively and accurately. Many natural lives, whether it is mollusk snails or other amphibians, reptiles, have the possibility of the existence of bacteria, viruses, and parasites, which can be said to be universal. However, we cannot judge that these organisms carry bacteria, viruses, and parasites as the main basis for their harmfulness.”

At present, the CBCGDF research department has established a research group to conduct a comprehensive study on the causes, sources, spread, growth, especially ecological effects of Pomacea canaliculata, and countermeasures. As an expert representative of the research team, Dr. Zhou also welcomes the active participation of all sectors of society.
