Green Club Biological Control Group | Rural Fushou Luo Survey (2)

The big man on the left is Fushou snail; the right side is the local field snail.

The picture was taken on August 7, 2022. The Chinese Biological Diversity Protection and Green Development Foundation (referred to as the China Green Fair and Green Club) biological prevention and control work group and the Green Club volunteers went to a province to conduct foreign invasion species in a province - -The field survey records of Flyingn Apple Snail, Latin Name Pomacea Canaliculata).

The snail in the picture above is the native field snail. Tianluo Pan refers to the software animal of the field of the family, which belongs to the software animal door abdomen, and the abdominal and foot of the field. Tianluo is distributed in most parts of China.

According to local people, before the Fushou snails did not come in the past, the dams, ponds, and fields in the local country were everywhere. Tianluo is also a food that local farmers love. With the barrel out of the snail, you can fish for half a barrel.

In recent years, when Fushouluo did not know when to settle in the local area, farmers gradually discovered that Fushouluo is everywhere in the fields and streams. On the contrary, the local field snail is difficult to find now.

As one of the first 16 foreign invasive species to invade my country, Fushou snails have a wide range of foods and a large amount of reproduction. How do they kill the local field snail step by step? This issue is worth thinking about. Throughout the world, some foreign species with strong fertility have reached a new environment, because it may lack the control of natural enemies in a period of time, and if its breeding speed may be too fast, it is easier to grab the living space of other creatures, and then then As a result, ecological imbalance and decrease in other local species.

In fact, humans are not a effective link in the food chain -if it can be added with effective control and resource utilization; especially in the context of the market economy, you can consider using the power of market demand to collect and use the Fushou snails through Fushou snails. , Reduce its base, while harvesting high protein (such as consumption under the premise of safety, and as breeding feed, etc.), it also helps protect ecological balance.
