Release Qing Daofu?This is not a blessing, it is to make evil

Author:Species calendar Time:2022.09.15

Recently, a hot search for "release the Qingdao Fish". According to reports, on the day of the Mid -Autumn Festival, many people released the Qing Dao Fuyu in Chengbihu Reservoir, Baise City, Guangxi, and said that "the people are blessed."

However, the release of Qing Daofu not only does not do good deeds, but also destroys the ecological environment -after all, Qingdaofu is a well -known invasive species.

01

From fish tank to natural water bodies

Many people have heard Qing Daofu, and some people call them to eat shit fish, sucking fish, etc. They have successfully entered the living circle of the people from the traditional aquarium. The narrow "Qing Daofu" refers to the pTERYGOPLICHYS Pardalis, which belongs to the family (bone) family; Clean the fish tank.

There are more than 680 kinds of fishes in the family of nails, and they are all relatives of Qing Daofu. The name of the family of nails sounds unfamiliar, but it has another relatively familiar name in China -alien fish, especially in the aquarium, which is a very popular type of ornamental fish.

There are several obvious features in the fish family: a sucking mouth with teeth, and the body surface has a protective effect (so the English name also has the name of Armoured Catfish), a sensitive beard. This type of fish is mostly from tropical and subtropical regions in South America, and is distributed in Brazil, Panama, Costa Rica and other countries.

Many types of nails have been introduced in China, and most of them are in the aquarium. However, leopard patterns are not mixed well.

Qing Daofu (referring to leopard patterns, the same below) was introduced into China as an ornamental fish in the 1990s. After that, the pursuit of the aquarium market and the rise of artificial breeding, the market volume continued to rise. Qing Daofu grows rapidly, and can achieve sexual maturity in just two years. It is mostly used as a fish in the fish tank, which plays a role in auxiliary cleaning.

The threshold of the Qing Daofu's breeding is low, so more and more farming Qing Daofu entered the market, and the price fell. Some players who did not want would throw the Qing Daofu into the natural freshwater body. The Qing Daofu not only survived in many freshwater water bodies in China, but even established wild populations, so that some of the bottom fish from some freshwater river systems were Qing Daofu. This invasion also has a adverse effect on the local ecological environment.

In addition, due to the huge reproductive volume, and it can be directly collected through the wild, the price of Qing Daofu has continued to decline, and the level of entry ornamental fish has been come to the entry. Although it looks similar, it is not much different from the layman, but many imported relatives of Chiang Daofu have been difficult to reproduce and the import volume is limited, and the price has always stayed at the player level. In this way, Qing Daofu not only became the cheapest in the family, but was abandoned into the natural water body.

Ingredients or pets

In fact, many large -scale ornamental fish introduced in China are common edible fish in their origin; vice versa, such as the common Giro fish on the table of Yunnan -Guizhou area. Therefore, in addition to rich resources, a ornamental fish that can reach the size of the consumption size can be served at the dining table, which often depends on it (laughs).

However, such a thing seems to be unable to realize the common Qing Daofu.

In fact, the Qing Daofu captured in the natural water system is not small, with a body length of 20 to 30 cm, and individuals who are about half a catty can often be caught; historically recorded the maximum captured Qing Daofu 52 cm long. , Weight close to 1.3 kg. So, what is restricted that Qing Daofu becomes ingredients?

The main reason is the body structure of Chiang Daofu. First of all, Chiang Daofu has hard bone plate protection in the whole body. Except for the bone plate, the head and chest basically do not have muscle tissue. Only the back side has obvious muscle tissue to eat, so it seems less meat. Secondly, the appearance of Qing Daofu makes it difficult for many people to accept it as ingredients. At the same time, because the shell is hard and the cooking is time -consuming, it is not treated by the average person.

For the Qing Daofu in China, many people caught them. Sometimes the Clear Daofu, who can reach the size of the edible size, sometimes can't make your favorite (you don't want to raise it), and you can't be your delicious dish. However, in the place of origin of Chiang Daofu, some of the taorchi family are delicious ingredients, and barbecue and soup can be made.

Fight from the outside to a successful invasion

As mentioned earlier, Qing Daofu's survival and reproduction in China is not only understood by ordinary people, but also "alarmed" the government. The "famous" Qing Daofu has been included by the "List of Chinese Invasion for Foreign Invasion (Third Batch)" promulgated by the Ministry of Ecology and Environment. Everyone joked that Qing Daofu was the most successful invasion species -not only had no natural enemies, but even the Chinese who loved to eat could not take it (but the calendar mother had a serious face to reiterate: it is almost impossible to solve the problem of species invasion by eating food. To. As a fish from tropical and subtropical, the Qing Daofu has successfully made a smooth winter in the natural water bodies in the southern river of China and even North China. Because the whole body is covered with armor, there is no way to take it in the river in the river. Qing Daofu belongs to omnivorous fish. It has been searching for food at the bottom of the water for a long time. Therefore, he took a large number of underwater plants, native fish eggs, some fish fry, and even adsorbed and biting other fish. In a lack of oxygen, Chiang Daofu can rush to the water, and use the oxygen in the air to continue to maintain its life.

Qing Daofu's breeding ability should not be underestimated. In the place of origin, the existence of the rainy season and rainy season has limited the reproduction period of the Qing Daofu, but the Qing Daofu invaded to the southern waters of China has a longer reproduction period. They are mainly spawning in the autumn and winter season. It can lay eggs every month during the breeding period.

The reproductive Daofu will mate with holes in the water on both sides of the river, and then the male will take care of the fertilized eggs until the juvenile fish can move freely. This habit not only causes the embankment on both sides of the river to become increasingly loose, but also due to the lack of parenting and lack of natural enemies, the descendants have a high survival rate. As a result, the Qing Daofu successfully established a wild population in China.

In 2019, a study of the Qingdao Daofu population of the Guangzhou Freshwater System pointed out that the number of wild populations in the wild is on the rise, and necessary curb measures need to be taken urgently. The Qing Daofu not only flooded in China, but also in some areas of North America, the Philippines, Malaysia, Bangladesh and other regions in Southeast Asia, also suffered the distress of Qing Daofu's flooding in the wild. Therefore, the release of Qing Daofu seems to be the saving life of Chiang Daofu, but in fact, more local fish are dangerous.

Qing Daofu eat shit? You think too much

It has always been rumored that Qing Daofu is a garbage fish, eating shit fish, and aquarium players who buy it, just let it eat other fish in the tank.

In the early age of Qingdaofu, the rocks, nude algae, diatom and some animal and plant debris on rocks or bottoms were eaten; Qing Daofu, who was gradually growing up, took more animal foods to maintain the energy consumption of the body. Therefore, in addition to algae, fish eggs, some juveniles, etc. are its food sources. The Qing Daofu in the aquarium is more convenient than the moss on the wall of the fish tank.

The eaten shit in the field originated from the Qing Daofu at the bottom of the fish tank and continuously sucked the bottom of the tank with a suction cup mouth, indirectly disturbing or crushing the fish dung at the bottom of the tank, and the fish manure seemed to be gone. People mistakenly thought that the fish dung was eaten by the Taoist husband.

In the case of lack of food, Ching Daofu does crush the feces and then consumes the edible part of it, but in general, it will not take the initiative to eat ravioli. On the contrary, Chiang Daofu is a master of pulling Baba. Because of its long digestive tract, most of them have long stools and high excretion frequency.

What Qing Daofu really can help is to eradicate most of the algae that hinders the aesthetics on the wall of the fish tank. In addition, Chiang Daofu didn't mind the body surface of other fish (especially the ill fish) in the fish tank, but this would destroy the body surface tissue of other fish and cause damage to them.

The Qingdaofu can be described as a magical fish, not only in the tenacity of vitality, but also in all parties. Summary:

At present in many suitable freshwater waters in the southern China, Qing Daofu continues to achieve population growth. Due to the lack of predators, other fish or birds will even be stuck to death by their hard exostels because of swallowing Qing Daofu. Even It is difficult for people to handle them;

The cutting hole on both sides of the freshwater body such as the river such as the breeding period will affect the stability of the dam and easily cause the river bank erosion;

The long -term feeding of other fish in the waters of the Qingdaofu, aquatic plants, etc. will also destroy the diversity of the original ecosystem.

How to deal with such invasive species more effectively is a challenge in front of all of us. The "Biological Safety Law of the People's Republic of China", which started in April last year, stipulates that if it releases or discard foreign species without authorization, it shall be ordered to capture, recover and fine.

Regardless of the love of the ecological environment or the responsibility to yourself, please do not release it at will.
