Recently, Mr. Gu, who lives in Fengcheng Town, found that on the bank of the Chenghe River in front of his house, a lot of strange pink things grew, each of which was the size of a thumb. Mr. Gu is 71 years old and has never seen him before. After taking samples with a shovel, he consulted the eighty- or ninety-year-old elders in his family, and the reply he got was also unseen. Is this thing toxic? Is there any pollution to the river for a long time? With these questions, Mr. Gu contacted the relevant departments.
At 9:00 a.m., under the suspension bridge of the South Gate of The Chenghe Gate in Fengcheng Town, the reporter also saw these red unknown objects. Along the river, almost every few steps can be seen, pink, finger-shaped unidentified objects adsorbed on the inner side of the riverbank, which seems out of place with the surrounding environment. According to Mr. Yuan, a nearby resident, the river channel of the city did not appear last year, and after the weather became hot this year, the river channel gradually existed. Some residents also recall that since the passage of Typhoon Fireworks, there have been more pink unknown objects in the river.
"Ordinary people are worried about poison wow? Can you eat wow? Pollution wow? Especially now during the epidemic, the people do not know what? I'm afraid. Resident Mr. Gu worried.
With the arrival of the river maintenance personnel, the mystery was finally revealed. It turned out that these were the eggs of Fushou snails. As an invasive alien species, although there are many reports of the Fushou snail, the local residents are still relatively unfamiliar with its eggs. When the river maintenance personnel placed the salvaged Snails and adult eggs on the riverbank, the residents began to associate the two together and looked around.
Native to the tropical and subtropical regions of Central America, Fushou snail has become an invasive alien species worldwide, extremely harmful to aquatic crops, and may also become a carrier of disease and parasites. Due to the rapid reproduction speed of Fushou snails, if they are not cleaned up in time, it will also affect the diversity of local aquatic organisms. The biggest difference compared to the normal edible field snail is that the tail of the field snail is tapered, while the tail of the Fushou snail is relatively short. In terms of egg color, the difference is very obvious, the eggs of the field snail are transparent, while the Fushou snail is pink.
In fact, since the spawning of fushou snails in June this year, the fengcheng town water department and river maintenance personnel have been fighting with Fushou snails for several months. According to reports, Fengcheng Town found the red egg of Fushou snail about two or three years ago, which means that Fushou snail breeds locally. The conservation department also disposed of it at the first time, picking up the Fushou snail in the river channel and crushing it for burial, and directly crushing the snail egg to kill it. From the initial discovery of Hangtang Port to today's Chenghe, the rapid reproduction of Fushou snail has also attracted the attention of relevant departments. "There has been explosive growth this year, and there is also a growth trend from the perspective of the whole region." Chen Liang, deputy director of the Fengcheng River Chief's Office, introduced.
According to reports, considering that the elimination of chemicals may pollute the water quality of the river, the relevant departments mainly take the method of manual removal. At present, in Fengcheng Town, there are fifty or sixty pounds of Fushou snails every day. Due to the large area of grass-roots rivers, manual cleaning also has the dilemma of insufficient material and manpower. At present, the relevant departments are also seeking more efficient solutions to remove Fushou snails and protect the aquatic environment of the river. "We have also recently made a docking with the District Health Commission and the District Agricultural Committee, hoping that there will be a better solution to curb the local reproduction of Fushou snails." Chen Liang said.
Here is also another reminder to the public, found the traces of Fushou snail, please timely and the relevant departments to reflect. In addition, because Fushou snails carry many parasites, it is recommended that residents do not eat them.
