What species are rampant in the country? Are there any delicious but rampant species in our country?

Yes, tilapia and snail are species that can be eaten in our country but are still rampant, because these species have a strong reproductive ability and can quickly adapt to the surrounding environment.

There is no such widespread species in our country, because people in our country are more food-loving, so no species will be overflowing.

Know, crayfish, snails, scavenger fish, tilapia are all very delicious but overflowing species in our country.

There must be, for example, crucian carp is an alien species, and now it is also very flooded, and there are many special tasty.

In fact, there are quite a lot, and this one also needs to be differentiated, some are the proliferation of native species, and some are the proliferation of alien species.

Native species.

Stray cats and dogs are typical of this category. In fact, many of the causes of disasters are man-made. There are many people who are very enthusiastic about raising dogs and cats at the beginning, and after a few days of picking up and shoveling feces, they lose interest.

Then they threw the dogs and fur into the wild to destroy themselves, which led to many dogs and cats wandering in the wild, and then multiplied. In fact, there are many people in various cities who are helping them, but those people are discarding much faster than they can be rescued.

In order to solve this problem, it is actually very important to standardize the process of raising dogs and cats, and to establish relevant laws, and for dogs and cats that have strayed, they should be centrally managed and not allowed to breed on a large scale. This will make it possible to solve this problem once and for all. It is simply not enough to rely on people to help.

Alien species are overflowing.

In fact, China is also seriously affected by alien species, and has also published a list of three batches of invasive species, with a total of 53 species included in this invasive species list.

Eupatorium, Mikania, Hollow Lotus Grass, Ragweed, Poison Weed, Spartina alterniflora, Airweed, Hyacinth, False Sorghum, Cane Moth, Wetland Pine Mealybug, Mighty Beetle, American White Moth, African Snail, Fushou Snail, Bullfrog.

Lantana, Ragweed, Rhizome, Goldenrod, Tribulus terrestris, Silver Gum Chrysanthemum, Yellow Chrysanthemum, Nepeta, Amaranth, Sweet Potato, Eucalyptus Gall, Rice Water Weevil, Red Fire Ant, Crayfish Crayfish (Crayfish), Codling Moth, Clover Spotted Flyer, Pine Wood Nematode, Pine Scale, Coconut Leaf Bea.

Amaranth retroflexus, Diamond Aster, S. trifolium, P. mildeafensis, Sumatra liquor, P. sylvestris, Pseudostinkgrass, Xanthium spinosa, Morning Glory rotundifolia, Tribulus longifolia, Brazilian tortoise, Leopard catfish, Red-bellied sawfish, Nile tilapia, Red brown weevil, Plane square-winged netbug, Fuso cotton mealybug, T. spinosa wasp.

Let's take the water hyacinth as an example, it is also called water hyacinth, which originally grew in South America and is a very famous "pest grass". It was introduced to China because it was regarded as pig feed.

Because the reproduction rate of water hyacinth is extremely fast, and often large-scale outbreaks, it will lead to problems such as river blockage, resulting in drastic changes in the water body, large-scale consumption of oxygen in the water, will threaten the survival of fish, and the harm to the entire ecosystem is extremely great.

Therefore, invasive alien species actually cause great damage to the ecosystem.

The animal is eaten as a protected animal in China, but it is rampant abroad: kill 300 people

I think like some rats, flies, mosquitoes, locusts, these animals can flood China, and the Chinese are also very troublesome to solve these bugs.

Scavengers, because they have a relatively hard shell, are very difficult to be harmed, have no natural predators, and have been multiplied in large numbers in China. Become a local source of harm.

The only animals that can flood China are locusts, because locusts have a very strong reproductive ability and cause great damage to crops

Many people have seen tilapia, in southern China, this is a very common fish, even in the market has sold this fish, but in fact, tilapia is an alien species, its origin is Africa, this is a tropical fish, fast generation, high yield, miscellaneous food, less disease, strong fecundity, very suitable for farming, so it was introduced by the Chinese.

Now tilapia is one of the main aquaculture products in China, southern China, Guangdong, Guangxi. Hainan and other areas with higher temperatures often breed tilapia, and in the wild, the number of tilapia is also very large, many farms of tilapia, because of floods, release and other reasons, fled to the wild, in the wild to breed, in some waters in the south, tilapia has some flooding trend.

Tilapia is rampant in China, but the Chinese do not like to eat it.

Tilapia is actually a very good taste of fish, delicious meat, less spines, high protein content, with "white meat salmon", "21st century fish" and other titles, but in China, tilapia is not a very popular fish, China's native fish resources have been very rich, so Chinese prefer to eat native fish.

Tilapia, but does not meet the taste of many Chinese, a large part of the people think that tilapia has a strange earthy smell, so they are not willing to buy tilapia, so tilapia is not common in the Chinese market, especially in some northern areas are rare, in the origin of tilapia farming, the market sells more.

However, although Chinese do not like to eat tilapia, tilapia has not become an invasive species in China, but the aquaculture industry is becoming more and more vigorous, and it has become one of the hot spots of fish farming in recent years.

Tilapia, which is not popular at home, is a bestseller abroad.

Tilapia is a fish species that even the United Nations is recommending for farming, which is a cheap, but nutritious fish, and now there are more than 100 countries and regions in the cultivation of tilapia, with an annual output of more than 3 million tons, and China is now the world's largest country in tilapia farming, and in the past ten years, China's tilapia production is increasing at a growth rate of 9%.

In 2018, China's freshwater aquaculture output was 10,000 tons, and although China is a country with a large population, most of the tilapia produced in China is exported to foreign countries except for a small part of the domestic sales.

Why do foreigners like to eat tilapia so much? This is because tilapia is a very suitable fish for consumption, many foreigners will not pick fish bones, and tilapia does not have to worry about being stuck here, and this is a fish that is highly respected by scientific institutions, the United States Food and Drug Administration FDA and the Environmental Protection Agency issued the "National Healthy Diet Guidelines", tilapia is listed as one of the best choices in aquatic products, the United States has to eat catties of tilapia a year per capita, for many countries in Europe, and for countries in poor areas such as AfricaTilapia is a native fish, which is also cheap and a very suitable fish for consumption.

This organism is tilapia, which exists in many places in our country, and the reproductive ability of this creature is very strong, and it is one of the aquaculture products in our country.

I think it should refer to a type of seafood, tilapia, which is very popular overseas, so it is often exported in large quantities.

Seeing this question reminds me of the "four evils" mentioned earlier, and the definition of the "four evils" is different in each historical period. On February 12, 1958, it was proposed for the first time to complete the task of eliminating the "four pests" of flies, mosquitoes, rats, and sparrows within 10 years.

Under the call, a vigorous campaign to eradicate the "four pests" was carried out in various places, and the sparrow was identified as the main culprit of eating crops, so the finch hunting campaign was more intense, and the number of sparrows decreased sharply in more than a year, but it was accompanied by the phenomenon of insects everywhereTherefore, the call for "overturning the case" for sparrows became louder and louder, and finally after research and ruling, in March 1960, the slogan "Sparrows don't fight, replace them with bed bugs, the slogan is."'Get rid of rats, bed bugs, flies, mosquitoes'. ".

Although sparrows, one of the "four pests", are excluded and recognized as beneficial birds, whether it is the old "four pests" or the new "four pests" rats, flies, and mosquitoes, which can be described as overflowing, and these three animals are also notorious around the world because of their strong environmental adaptability and fast reproduction.

However, the size of the animal population is closely related to the biological chain, and due to the loss of natural enemies or the decrease in the number of natural enemies, it will inevitably cause some animals at the bottom of the food chain to reproduce wildlyThe most typical example is that in the 70s of the 19th century, rabbits invaded Australia as an alien species, and in less than a century and a half, from the initial 24 to the current tens of billions, although Australia has natural enemies such as golden eagles and lynxes, rabbits are naturally sensitive to burrows and reproduce quickly, giving birth to 4 litters and 6 litters a yearAnd the two uteruses multiplied together, which is simply fast.

However, due to the destruction of the ecological environment and overfishing, the number of snakes, frogs, dragonflies, eagles, snails and other species has decreased sharply, so flies, mosquitoes, rats and other pests have always been flooded.

However, it is certain that as long as the animals can be put on the table and can be put on the elegant hall, they can be eliminated by opening their mouths, and it is impossible to overflow.

Rats have been infested, fields, shops, factories, high-rise buildings, the destruction is so strong that anyone who can bite can bite. It's elf, it's hard to catch.

In China, to be honest, there really isn't. If there is a flood that can eat, the Chinese can definitely eat it.

Because some animals need to be protected, there are more animals.

So does this mean that there is no animal overrun in China? In fact, we often eat crayfish every day.

There are many animals that can do it, such as various examples of biological invasions.

There are many animals that are rampant in China, such as scavengers.

For example, there are a lot of cockroaches and locusts in China now.

Many animals are infested in China, such as cockroaches and so on.

What is the reason why "it", which has become a protected animal in China, is flooding in the United States?

I don't know anything yet, because the Chinese eat everything.

Personally, I think it should be rats, because very few people in China eat this thing.

The species on the earth are originally very homogeneous, and there are not many species. Over time, as the environment has changed around the world, resulting in environmental diversity, the original species had to adapt to the environment in which they depended in order to survive, so that the species evolved in different directions. This results in a diversity of species.

From the perspective of the food chain, the diversity of species makes the food chain of each friend form a food web, which is conducive to the stability of the survival of the species.
