With the development of globalization, the exchange between countries has become more and more common, although it has made the economy of many countries develop better, but it has also brought some negative effects, species invasion is one of the negative effects, species invasion did not start in modern times, but it began to become rampant in modern times, the main reason is because of the exchange between countries and many invasive species will follow the footsteps of human beings to different countries, And each country's ecosystem is unique, evolving over hundreds of thousands of years to reach a balance that invasive species can upset.
Species invasion in many countries, but in different countries the consequences of invasive species are not the same, some countries and regions are very vulnerable to invasive species, such as Australia and Florida in the United States, because the local ecosystem is relatively fragile, and modern times is a very easy migration of species era, which also makes these places become often invaded by invasive species, Europe is the same, in the eyes of Chinese foodies, some invasive species in these countries, people are very speechless, For example, australian rabbits, American Asian carp, and European crayfish, oysters, etc., are very popular foods Chinese, and there is an invasive species in France that also makes Chinese tourists feel very hungry.
Such an invasive species is the European catfish, the largest fish in Europe and the third largest freshwater fish in the world, with an astonishing wide mouth filled with rows of fine teeth like sandpaper, hundreds of them. It is a very sophisticated hunter, few animals can escape its "magic mouth", although this giant catfish is a native fish in Europe, but it is not available in France, but as a European country, in 1983, this giant catfish came to France and began its journey of domination over France.
European catfish has been coming to France for more than 30 years, it has caused serious damage to the ecological environment of France, this is a very aggressive fish, France is the most endangered area in the world, of which 20% of the animals are endangered, part of which is because of this giant catfish, it is a very large amount of food, and the diet range is very wide fish, even the pigeons flying in the sky are often attacked by it, and there are a lot of amphibians and fish that are eaten to extinction by it. In Europe, it has no natural enemies, but also makes it more and more numerous, growing bigger and bigger, many giant catfish are more than 1.5 meters, and began to attack humans, in 2008 a man was attacked by it, and scientists found human remains in the stomach of this giant catfish, so people call it "man-eating catfish".
Now this catfish in France has caused very serious economic losses, but also greatly damaged the local ecosystem balance, so that the French people are very headache, but many Chinese foodies see this catfish or very much want to taste, after all, such a large fish, or make people very appetizing, and the meat of this fish is tender, the nutritional value is still very high, netizens said that if in China, it will not have the opportunity to grow to "piranha" so big, but will become a dish. What do you think about that?
