Seriously affecting the lives of local people, after Germany, another country crayfish flood, how to

Ecology is really very important for a region, many people have no concept of ecological destruction, think that it has little to do with themselves, but this is not right, China because of the huge population base, it is true that there are not many overflowing species to harm the world, but we can not be complacent about this, such as the hare in Australia, the flood of a hundred years, I don't know how much vegetation and grass roots have been eaten, so that the Australian grassland area is small and small, seriously affecting the development of animal husbandry and agriculture, And that's something we need to be on guard against.

If you want to say that the most successful flood species in China, there should be such a few categories, the first tilapia, which still occupies the north and south of the river, almost all freshwater basins have its figure, and the other is water hyacinth, but I heard that it has begun to disappear again, and it is not so flooding. Next is the "scavenger", an invasive species that particularly distresses Chinese foodies, which is now present in many regions, but it is not in a rut, but if you want to say that the most successful invasive species, it should still be the "crayfish" species.

Crayfish is a freshwater economic shrimp, China in the 20th century 30-40s when introduced from Japan, but its origin from the United States, when the main role of this shrimp is as food and pets, once it appeared in China's farmland water, it quickly established a population, because it is particularly adapted to temporary water bodies, and the diet is particularly extensive, so it spreads and spreads, and suddenly becomes a "pest", to local fish, crustaceans, aquatic plants have posed a threat, It can also cause the loss of irrigation water and the destruction of fields, so many farmers hated it fiercely at that time, but no one thought that in just a few years, crayfish was controlled and became the main dish of the current night market food stalls, and even needed artificial breeding to meet the consumption rate of Chinese, so it was the most successful, but in fact it was also the most unsuccessful. But this most failed invasive species has successfully "captured" a country, do you know that it is?

<> the flood of crayfish is rampant around the world, except for the deflated in China, most of the area is difficult to control, there has been a crayfish flood in Germany, and now this crayfish has invaded the country of the Netherlands after conquering Germany. According to reports, crayfish in the western part of Friesland in the Netherlands have been overrun, not only breeding in large numbers in the water, but also taking over the city's roads and streets, leaving local residents very distressed and afraid to go out for walks or go out to walk their dogs. The main reason is that such flooding is particularly serious to the local ecological damage, nesting lobsters may cause a large loss of local farmland, but the Dutch have no way to do this, because they do not have the natural enemy of crayfish here, herons, and are not interested in eating crayfish, so the local authorities announced that they are anxious for the expert group to carry out biological research, hoping to develop a way to effectively control the number of crayfish.

Eat. Because crayfish are delicious and very tasty, making them into a delicacy is a great solution.

The crayfish in the Netherlands are overflowing, and the local ** isolates the crayfish, at least it does not affect the lives of the residents; But I think they should be transported to the Chinese, and the Chinese can eat them to extinction.

They should all be shipped to China to be sold, after all, Chinese foodies are very good at solving these problems.

May 16 -- Berlin, the capital of Germany, has been plagued by flooded crayfish in recent years, especially last summer, crayfish even poured into the streets of Berlin "rampant", the local ** has introduced natural enemies but the effect is not good. Recently, a Berlin fisherman was granted a fishing and marketing permit. Foodies can finally contribute to "this ecological problem"!

In this regard, some Chinese netizens said that they hoped to "solve problems" for Germany, and said that the problem would be solved in three days.

Deutsche Welle radio **May 13** said that the crayfish that "occupy the road" will soon be on the table! In Berlin, the capital of Germany, crayfish were once overflowing, and because it could not be ruled out that the crayfish roaming around had excessive levels of heavy metals and other harmful substances, these crayfish were not used commercially but were killed. This summer, due to the "comeback" of crayfish, Berlin decided to "lift the ban", and recently issued a relevant fishing and sales license to a Berlin fishing workshop, allowing crayfish to be fished, and ** to restaurants and ordinary customers.

Staff at the fish farm said more than 2,000 crayfish were caught in just one week.

According to CCTV news reports, the crayfish from afar may not escape the fate of being put on the table in the end. Seeing that the German people are hollowing out their minds in order to solve the craving of crayfish, netizens around the world can't sit still and have "offered suggestions" and gave their own solutions.

Nowadays, the more common ways to eat crayfish in Germany are: crayfish avocado pasta; crayfish cream soup; Crayfish sandwich bread and crayfish salad, etc. However, this obviously does not satisfy the appetite of foodies from all sides.

It's time to go, foodies" "The hand speed of peeling shrimp is too slow, I can't wait to help him" "Spicy crayfish, brine crayfish, braised crayfish, garlic crayfish, really don't think about it?" Some netizens said that they were happy to "solve problems" for Germany, and some netizens ridiculed that bringing 100 Chinese there would solve the problem in 3 days.

It is reported that crayfish have strong adaptability, feed on plants, small fish and fish eggs, and grow rapidly. The crayfish that are rampant in Berlin are native to North America, and due to the good water quality of lakes in Berlin Tiergarten Park and the continuous warm winters in the past few years, the "immigrant" crayfish have rapidly multiplied here and the population has surged. Berlin** has banned fishing because of concerns about crayfish containing harmful substances such as heavy metals in its body, and introduced natural enemies such as eels, but the number of crayfish has increased instead of decreasing, which has caused ** a big headache.

Ehler, a wildlife expert at the Berlin Senate's environmental department, said that after an inspection of crayfish caught last year, it was found that there were no safety hazards of excessive levels of harmful substances such as heavy metals. Ehlert stressed that all crayfish sold must be inspected to ensure that there are no safety hazards before they can be sold. With the exception of fishing workshops, crayfish fishing is still prohibited for now.

At the same time, despite large-scale catches and attempts to use "natural predators" against crayfish, the number of Berlin crayfish has increased further.

Crayfish is a great favorite of the Chinese, especially now that the weather is getting hot, at night at the food stall to serve a spicy crayfish with a cold beer, listening to it is enjoyable. Westerners aren't keen on crayfish, though. In Berlin, the capital of Germany, the city had to beg citizens to eat crayfish in order to curb the rapid reproduction of the species in the local area.

Since last summer, crayfish have been breeding rapidly since they appeared in Berlin's Tiergarten district park. According to German regulations, it is forbidden to catch and grill these crayfish. But now in the face of menacing crayfish, the city of Berlin** is encouraging citizens to eat them.

Dirk Ehlert, Berlin's environmental protection department, said that research has shown that the freshwater crayfish, which originates in the southern United States and northern Mexico, are safe to eat, and the city has issued a permit to a local farm to catch crayfish in two Berlin parks, for restaurants and regular customers. So far, about 4,000 have been caught, Ehlert said. However, the city of Berlin** still does not allow ordinary citizens to catch crayfish without permission.

Crayfish are omnivorous, fast-growing, and adaptable, allowing them to form a competitive advantage in the local ecological environment. In August last year, crayfish began to appear on the streets in Berlin's Tiergarten district, and the most dense at that time was in front of the Spanish Embassy in Germany, and the number of them also attracted widespread attention from social **. The local fisheries department said the water quality in Tiergarten was good, meaning the crayfish may have migrated there to expand their breeding.
