Three people in Guangxi released alien creatures in the reservoir " Scavenger "
Recently, according to Jimu News, a harmful fish species "scavenger" was released in Chengbi Lake, Baise, Guangxi. . From the online video, we can see that more than a dozen scavengers and other fish were put into a black plastic bag, and after the releasers came to the waters of the Chengbi River by boat, they opened the bags and went to the lake.” "Pour in" these fish, with blessings on their lips. It is understood that there are three people in the group of releasers. Among them, Mr. Luo, the person involved, said the blessing. He said that he has always had the habit of releasing animals, but most of the fish released before were ordinary fish such as koi. The reason why he bought a scavenger this time is because the fish market owner said that this fish is suitable for release and that it is not harmful to the ecological environment. He made such a big mistake. After the news of
was posted on the Internet, there was an uproar immediately. Some netizens said that the crocodile gar has not stopped, and now the scavenger is released, what are these people's intentions? In addition, some netizens said that "the illiterate release" must be rejected, otherwise it will bring extremely bad consequences to the ecological environment. However, why do netizens hate scavengers so much? How should the behavior of "freeing the illiterate" be resolved? Pay attention to the universe walker, and follow Xiao Zhou to explore all things in the world.
Scavengers
Before answering the above questions, let's take a brief look at scavengers. The scavenger, scientific name "leopard fat catfish", also known as sucker fish , anglerfish , garbage fish , is native to the Amazon River Basin in South America. The scavenger is dark brown overall, with a rough, black-spotted body surface, and a flat head with a towering dorsal fin. From the appearance point of view, the main feature of scavengers is that there are abundant suction cups in the inferior position of the mouth (that is, the opening of the mouth to the abdomen). They are adsorbed on the aquarium wall or aquatic plants through the suction cups to lick moss or other water stains, so they are called "Scavenger" in the water.
In the 1990s, scavengers were introduced to my country through aquarium trade as a kind of ornamental fish. Because of their strong cleaning ability, they were used as tool fish in cleaning aquariums. However, later, due to reasons such as abandonment and breeding escapes, scavengers began to breed in the wild and gradually expanded their scale. So far, scavengers have formed invasions in several countries. But then again, almost every country has invasive alien creatures. Why do people hate it when they talk about scavengers?
The harmfulness of "scavengers"
This is about their harmfulness. Although scavengers have the ability to clean up debris in the water, they are more destructive. First, the scavenger will eat the eggs of other fish in the water. According to incomplete statistics, scavengers can eat about 5,000 fish eggs a day, and they will also devour fry, posing a threat to the survival of other fish. Secondly, scavengers will destroy the ecological water environment. While they devour fish eggs and fry, they will also eat a lot of aquatic plants, which will cause the water body to suffer from hypoxia. Finally, when it comes to the general ability of invasive alien organisms, it is a strong ability to reproduce and survive. According to the data, scavengers can survive with almost water, and there are no natural enemies in the country, so scavengers can easily flood into disasters. For example, in June this year, the staff of a park in Quanzhou found that the lotus flowers in the park were not growing as well as in previous years. After investigation, they found that there were a large number of scavengers in the pool. When fishing, professional fishing personnel will catch 400-500 catties of scavengers each time, which are also mixed with exotic species such as Brazilian turtles and crayfish. So, how serious will the invasion of by alien organisms from be to our country?
What consequences will the invasion of alien organisms have on our country?
In recent years, the number of invasive alien species in my country has been on the rise. So far, more than 660 invasive alien species have been discovered. The reason why invasive alien organisms have a serious impact on my country is that on the one hand, they reproduce too fast, which brings a certain threat to the survival of native species in my country, such as water hyacinth .
Once the water hyacinth takes root in the water, it will spread all overA large number of other aquatic organisms died due to lack of oxygen and insufficient sunlight, and the ecological environment of the waters was severely damaged. On the other hand, there are no natural enemies in China, such as the scavengers we mentioned above. Once they multiply in excess, not only will the ecological environment of our country be seriously damaged, but the native fish will also face threats to their survival.
In fact, one of the reasons why invasive alien species are flooding in my country is man-made, taking fish as an example. Most people think that releasing animals is a "good deed", but they don't know that releasing fish is also very important. For example, the scavengers released by Guangxi men and the crocodile gars that appeared frequently in various places a while ago belong to a kind of "literate release". The so-called "release of illiterate people" refers to those who only want to release fish or pray for blessings, but do not care whether releasing fish will harm the ecological environment. For example, the "Henan Strange Fish", the crocodile gar, has been making a lot of noise a while ago. In order to catch the alligator gar, the local government spent nearly a month draining the lake, and finally managed to capture two alligator gars hidden in the water pipe. The alligator gar will appear in the artificial lake because someone secretly released it here.
Furthermore, a large number of dead fish appeared in Suzhou River in Shanghai some time ago. The reason was that people released a large number of fish into the river in order to pray for good luck. In the hot summer, the lack of oxygen in the water brought about by the high temperature and the temporary unsuitability of the fish released by people led to the scene of a large number of dead fish floating on the river. This incident has also been ridiculed by people: "good deeds" become "evil deeds", and "release" becomes "killing".
Therefore, I would like to remind everyone here that you must not release alien species for the so-called "blessing", because you don't know how big the consequences will be. Furthermore, if you want to release life, you should choose a scientific way of releasing life, rather than "releasing life for illiterate people". What do you think about this?
