What comes to mind when you think of invasive alien species? Data show that in China, the direct and indirect losses caused by invasive species total up to 200 billion yuan per year. With the development of the times, the speed of the flow of people has accelerated, and the invasion of alien species has become more serious, which is inevitable. However, for the majority of foodies, not all alien species must be resolutely cracked down, and some alien species are still in short supply.

4 "arrogant" invasive species, 2 are disliked, 2 are bought and eaten, do you know? Recently, there is more news about the invasion of alien species, there are 2 kinds of people who hate people, and they basically have to deal with it when they encounter it, while the other two have become regular customers on the table, many people like to eat, especially the night market food stalls, almost all of which can meet its figure.

What are these 4 "brazen" invasive species? Let's start with 2 types that no one eats.

The first, the scavenger fish

The scavenger fish is an invasive species, some people rate it as one of the most disgusting fish in the world, and its appearance is also very ugly, and in some places even call it a garbage fish.

The reason why this fish is called scavenger, and its living habits are not unrelated, scavengers like to eat rotten things in the water, and some dirty things it can eat, the water quality can be said to play a purifying role, just like the cleaner, its origin is in South America, this fish has no natural enemies in the country, and it is very easy to survive, reproduce rapidly, it is very difficult to die.

This fish is basically uneaten, ugly, and can be produced in any place with a worse environment, even if you want to eat it.

The second species, the alligator eel

Recently, if you pay attention to the news, you should be familiar with an exotic species, that is, the alligator eel, which is found in more than ten provinces in the country, and this fish is native to North America and generally lives in rivers and lakes.

Some experts say that it "has no natural enemies, and once it enters the natural bare waters, it will eat all the local fish species." It can be seen that its harm is very large, as a large carnivorous and fierce fish, the crocodile eel is also known as the "water killer" because of its rare natural enemies, fierce temperament, omnipotent eating and other characteristics.

So far, I have not heard of anyone eating crocodile eels, first, it has not yet formed a scale, and second, the harm of this fish is too great, and there are few large-scale breeding.

2 invasive species that people really like to eat

The first, crayfish

There are about 660 species on the list of invasive species in China, of which the crayfish is one of them, which originates in the United States and was originally known as protocellfish. The reproduction rate is extremely fast, and the damage to crops is quite severe, but fortunately, many people love to eat.

Today's crayfish has long become a signature food, in many places in the night market, it has become the main dish, and a spicy crayfish, the price is not cheap, often one or two hundred, but people's demand is still very large.

After the crayfish is fried and then cooked in the sauce, the taste is Q bomb, and it is still more enjoyable to eat.

The second species, giant river prawns

Giant river prawn, also known as freshwater long-arm prawn, Thai shrimp, Malaysian prawn and so on. Giant river prawns are a group of light and marine shrimp, but most grow up in fresh water. This shrimp grows very quickly, with a body length of up to 1 meter, and it is more common in China's river channels, as long as it is in the water with sufficient food, its size can even grow larger.

This shrimp people also like to eat, its taste is delicious, the size is much larger than the average shrimp, the protein content is also quite rich, and now it is farmed in many places.

Whether this shrimp is steamed or fried, the meat is delicious, eating or more enjoyable, friends, have you eaten?
