The storm of fishing for crocodile gar from the draining reservoir in Ruzhou, Henan has not yet calmed down, and another accident happened at Chengbi Lake in Baise, Guangxi.
It turns out that on the day of the Mid-Autumn Festival , someone from posted a video online. In the video, there are three men carrying several black plastic bags, and they are throwing something into the lake. When the camera zooms in, I can see clearly what is being delivered. It's scavenger !
and the "releasers" had a smile on their lips, and they were talking about something while putting it in their mouths, which made people doubt their true intentions, which also caused public anger! So what is the truth? Why does throwing a scavenger make people so angry?
"Release" the scavenger is actually "praying"
On September 10, 2022, in the Chengbi Lake Reservoir in Baise, Guangxi, three men took a boat to the center of the lake, took out a few black plastic bags and put the scavenger into the lake. While putting it in his mouth, he read "Blessed is the one who sees it", and the scene was "very weird". After the
video was posted on the Internet, it immediately entered the hot search list, causing heated discussions among netizens.
On the other hand, Baise Yongle Police Station and other relevant departments also began to intervene in the investigation. This time, the "releasers" were not as lucky as last time. Soon, the police found the "protagonist" of this incident, Mr. Luo, based on the information provided by the video.
In front of the police, one of the parties, Mr. Luo, was very scared. In the face of the camera, he expressed his shame, constantly apologized to the police and the audience, and expressed his willingness to accept punishment. His voice was crying, and it seemed that he was really thinking about it.
He told the police that he did not know the scavenger before, let alone that this fish would cause irreversible damage to the ecological environment. only knew that this fish was called "scavenger", and the proprietress who sold fish in the market told him that it meant that it could remove the silt from the bottom of the river, so he and two other people bought more than a dozen "release" ones, originally for the purpose of Good thing, but I didn't expect things to turn out like this.
And before that, he has always had the habit of "release", but he only released ordinary fish before. He also said that "release" is for "blessing", not as netizens speculated, hoping to get the majority of netizens. forgive. Although Mr. Luo has been very sincere in front of the camera, there are still many netizens who "do not buy it", and even feel that Mr. Luo and others are suspected of "selling miserably", which has set off a new round of discussions.
put in the scavenger is "release" or "kill"
netizens gossip, have different views on this matter. Some people think that freeing the scavenger at will is a major event, and it cannot be let go with just an apology, at least a heavy punishment is required, so as to kill the chicken and serve as a warning to the monkeys; some people think that the behavior of Mr. Luo and others is not "freeing the life". , but "killing", and the other fish in the lake are probably "inferior."
However, some people expressed sympathy for Mr. Luo and others, and felt that Mr. Luo and others had good intentions, but their fault lies in ignorance. In order to more effectively prevent such incidents from happening. So, is the release of the scavenger "release" or "kill"? Why is everyone shunning creatures like scavengers? What the hell is a little scavenger?
"scavenger" life experience revealed
scavenger is an omnivorous fish, native to South America, like alligator gar, Brazilian turtle, fushou snail and tilapia and other creatures belong to foreign countries in my country invasive species. Because of its peculiar shape, likes to attract things, so it is also called " sucker fish " or " garbage fish ".
was first introduced because it has the function of removing algae in the fish tank, and it also has a good effect on purifying water quality.
and this kind of fish is not big, adult scavengers can only grow to 30cm at most, they are covered with black lacquer patterns and spots, and they swim very beautifully in the water tank, so this is also when it was first introduced. Popular with fish loversFavored reason.
The scavenger mainly lives in the southern region , because it is a tropical fish and likes to live in the water temperature of 22°C~26°C, and the water temperature in the north is too low in winter, it is not suitable for it to survive at all, so the southern region with a warm climate Nature has also become their first choice for survival.
, especially in Guangdong, is literally flooded. Despite its small size, is very cute. In fact, they have a ferocious personality, and once they multiply in large numbers, it is more difficult than going to the sky to invite them away. Seeing this, some people may ask, since he can remove dirty things, it is good for the environment, why do people avoid it?
The dangers of scavengers
First of all, like other invasive species, scavengers are especially edible, especially after adulthood, they not only eat moss and algae, but also the eggs of other fish, and they eat a huge amount of food. It can eat 3000 to 5000 fish eggs a day, and does not let go of the newly born small fry , so it is also called "the killer of freshwater fish".
is not only that, it will also attack the plants. When the number of scavengers in the lake is large enough, all kinds of plants in the lake will be eaten up. is no exaggeration to say that where there are scavengers, the entire waters will suffer.
Secondly, scavenger has super reproductive ability . After being introduced into China, it basically has no natural enemies, and their vitality is very tenacious, and they are not particular about water quality. Therefore, as long as there are a few scavengers in a water area, I believe they will soon become a group, or even occupy the entire water area. . But this kind of fish has rough flesh and a lot of parasites, so it can't be solved by eating it like crayfish and other invasive species.
Finally, due to the excessive number of scavengers in , other local fish could not survive, and the number of fish species in the waters of decreased, which led to the destruction of the ecological chain and finally broke the ecological balance. At the same time, many farmers have suffered heavy losses because of them.
Therefore, as an invasive species, the destructive power of scavengers may be stronger than that of alligator gars, which is why netizens are so indignant. According to relevant survey data, since 2015, my country has carried out large-scale scavenger arrests every year. The number of scavengers caught every year exceeds 100,000 kilograms, but this number is far from clear. Doffer's reproduction rate. It can be said that scavengers are undoubtedly the "nail households" in our country.
However, it stands to reason that as long as the scavenger-infested area is well controlled, won't other places be "contaminated" by scavengers? However, the reality is far beyond our imagination.
"Release" scavenger activities are still going on
In recent years, scavengers have flooded into the south, and one of the main reasons for is the participation of a large number of "release" believers. Many people, like Mr. Luo, heard that the scavenger had a good "meaning", and many ignorant people also began to join the ranks of "release" and went to the market to buy them for release. In fact, the act of "freeing animals" does not "pray for good fortune", but will cause other fish to become the "dish on the plate" of the scavenger.
In addition, some people originally kept them as ornamental fish , , but as the scavenger grows bigger, the appetite will also increase, so they feel that the cost is too high, so they find a place to release them. , but the consequences are disastrous, which is also the reason for the flood of scavengers.
Therefore, the author believes that the release of life is a good thing, but it does not mean that it can be "blindly released". invasive species are extremely destructive to the ecological environment. If this behavior is not stopped, the consequences will be unimaginable . It is hoped that the relevant departments can severely punish this so-called "release" behavior, and at the same time, strictly investigate the source and cut off the trading chain, which is also a "merit"?
