Recently, a netizen posted a message saying that someone brought several invasive fish species " scavenger " to the Chengbi Lake Reservoir in Baise City, Guangxi, and said, "Those who see it are blessed." The matter aroused heated discussions, and on September 14, the entry of a scavenger for releasing harmful fish species from a reservoir in Guangxi was posted on Weibo. The latest report shows that the party, Luo, has come to the case and publicly admitted his mistake, saying that he will fully cooperate with relevant departments to save the case in the future.
Releasing "scavengers" is not a good deed,
actually destroys the ecological environment
It is understood that scavenger fish has strong adaptability, fast reproduction, and low oxygen resistance, and grows very fast in natural waters in my country. The adult scavenger has a huge appetite. In addition to algae such as moss, it will also feed on the eggs of other fish. It can eat 3,000 to 5,000 eggs a day, and it will also swallow the fry. And with hard and rough scales, there are almost no natural enemies in our natural waters. At the same time, scavengers are bottom fish and have suction cups on their snouts, making them extremely difficult to catch with traditional nets. The popular science account "Species Calendar" said that from the characteristics of "scavengers", scavengers can almost be called the most successful invasive species. Regarding this incident, many netizens expressed their attitudes one after another, with @pork chop some love commenting that "this so-called release is actually evil". @徐海涛Wisdom Xiaohuya commented, "The release of life has become the release of killers to kill, and the releaser still has to think more about it!" It is also necessary to guide the public to participate in it, and to increase relevant laws and regulations and popular science publicity to raise people's awareness of prevention and control. Just like the "scavenger" incident in this release, the man involved said that he has always had the habit of releasing ordinary fish. Before releasing ordinary fish, he did not know the scavenger and did not know its harm. In this regard, netizens expressed that it is urgent to strengthen relevant science popularization.
The popularity of "release" has risen,
The invasion of alien species should not be underestimated
Recently, "release" has become a hot word in public opinion. In August of this year, Ruzhou City, Henan Province, almost drained the water in the Central Park Lake. The reason for the mobilization is to catch the alien species, the crocodile gar, and this "strange fish" native to Central and North America is By raising pets and releasing them into the wild in China, if they are allowed to harm the lakes, once they establish natural populations, the damage will be more long-term, and may even lead to the disappearance of some native aquatic organisms. In addition, there have been frequent reports of the invasion of alien species such as water hyacinth , Brazilian turtle, fushou snail , canadensis , etc. Such alien species invasion not only threatens human health and local animal and plant ecosystems , but also caused a lot of losses to our economy.
my country has always attached great importance to the prevention and control of invasive alien species. In 2003, 2010, 2014 and 2016, the " List of Invasive Alien Species in China " was published in four batches. It is included in the "List of Invasive Alien Species in China (The Third Batch)" issued by the Ministry of Ecology and Environment of China. Even so, the situation of alien species invasion facing our country is not optimistic. On June 5, 2020, the World Environment Day, the Ministry of Ecology and Environment released the "2019 Bulletin on the State of China's Ecological Environment", announcing that more than 660 invasive alien species have been discovered in my country, with a wide variety of species involving plants and aquatic animals. and pests and other fields, a variety of ecosystems.
In order to further prevent the invasion of alien species, in June this year, the Ministry of Agriculture and Rural Affairs, the Ministry of Natural Resources, the Ministry of Ecology and Environment, and the General Administration of Customs jointly issued the "Administrative Measures for Invasive Alien Species", highlighting the need forStrengthening the supervision of the whole chain requires that all relevant departments and local governments must strengthen the prevention and control of invasive alien species from the source prevention, monitoring and early warning, governance and restoration and other links, and build a whole-chain prevention and control system.

adheres to the defense line of alien species invasion,
needs top-down cooperation with
At the beginning of the introduction of alien organisms, they are either endowed with beautiful functions, unique genes, or efficient good expectations. Creatures such as "Fu Shou Snail", "Scavenger" and "Brazil Turtle" have appeared in everyone's field of vision more than 20 years ago. At that time, "Fu Shou snail" was introduced as food, "Brazil turtle" was used as a sales gimmick with "easy maintenance", and "scavenger" was used as a fish tank cleaner.
The "scavenger" of this incident was included in the "China Invasive Alien Species List" with the scientific name "Leopard-printed catfish". However, for ordinary consumers and businesses, firstly, it is difficult to study the list of invasive alien species from , and secondly, the scientific names in the list seem to be very far away, and it is difficult to relate them to the creatures in daily life. Therefore, when the relevant departments carry out governance, they should not only start from the perspective of the source of entry and the formulation of laws, but also “down the market” and “down-to-earth” to publicize the types of alien species and the hazards of invasion to the public. In terms of market management, businesses involved in the sale of exotic species should be supervised, and biological circulation paths should be fully controlled. At the same time, with the rapid development of social networks, the public can also exert their right to supervise by public opinion and reflect on the invasion of alien species. As a result, from the government to the public, from top to bottom, cooperate and jointly build a defense line against the invasion of alien species.
