When it comes to invasive species, many people will say that China's population is large, and there is basically no flooding, of which crayfish is a good example, and it is often mentioned.
However, there are also some invasive species that are now flooding in our country but there is no way. Today the author wants to talk to you about this kind of fish is like this, it has not yet been flooded in our country, and loves to eat juvenile fish and fish eggs, a day can eat up to 5,000 fish eggs, even foodies take it no way, but there are still people who love to raise it. If you see this fish in the wild, don't be soft.
<h1 class="pgc-h-arrow-right" data-track="4" > popular science for catfish</h1>
Catfish was a highly rated freshwater fish before the folk of our country, and many people also like to eat it. But later after the Egyptian pond catfish came, because this fish loves to eat feces, it can survive in the sewage ditch full of garbage, many people will be beaten to death with a stick, and regard China's catfish and Egyptian pond catfish as "garbage fish", and then do not love to eat.
In fact, when it comes to catfish, there is also an invasive species that looks very much like catfish, which, like the Egyptian pond catfish, is also very adaptable and can survive by eating garbage, which is the lower catfish native to Latin America.
The lower catfish is also called strong waist fish, waist treasure fish, or suction cup fish, angler fish, the scientific name is "king of the opposite sex". It is estimated that many people have not heard of these names, because most people in our country call it "scavengers".
This fish does look a lot like catfish, the body is semi-cylindrical, but the mouth is underneath, and likes to adsorb under stones and water bodies. When it was introduced to China, it was mainly hoped that it could remove residues, garbage and other wastes at the bottom of the water tank, so as to play a role in purifying water quality, so it was called "scavenger" in the folk.
<h1 class="pgc-h-arrow-right" data-track="9" > the hazards of catfish under the mouth</h1>
When it was first introduced to China, the catfish in the lower mouth is very good to feed, and it can grow well, the key is that it does contribute a lot to the purification of water quality, so it has been loved by many people, and they have been purchased as pet fish to breed.
But later, some people released this fish into the wild, hoping to use it to eat food debris and garbage in ponds and reservoirs to purify water quality. However, because I don't know much about catfish in the lower mouth, not only the water body is cleaned, but even the fish in the fish pond are much less.
The reason is that the catfish is called a scavenger, which is not an exaggeration, it not only loves to eat garbage and feces, but also especially loves to eat juvenile fish and fish eggs. The scavenger fish is very strong in life force, can also be eaten raw in sewage, when there is no food to eat, you can eat garbage, feces to survive.
And scavengers also love to eat juvenile fish and fish eggs, an adult scavenger fish, a day can eat 3000-5000 fish eggs. And their diet is still very large, even some sick big fish will prey on. If there is a scavenger in a river, the other fish will suffer. The big fish, the small fish and the fish eggs are all eaten to the fullest. Moreover, the scavenger fish eats more, the excrement is also a lot, and its harm is very large, which will make other fish sick, unable to survive and die.
<h1 class="pgc-h-arrow-right" data-track="14" > flooded many places in the south, and foodies can't do anything about it</h1>
In the southern region, as early as 2000, catfish were seen in the rivers in many places, and there was a tendency to flood. In recent years, flocks of catfish have been seen in some rivers in guangdong, Guangxi, Hunan, Hubei and Fujian provinces.
This is not only because the lower catfish has a strong vitality, and the reproductive ability is also very strong, the key point is that this fish currently has no natural enemies in China, naturally it is more and more, thus causing great harm to the local ecological environment. Even many foodie friends have said that there is nothing they can do about scavengers.
The reason is that the scavenger fish is really unpalatable, and most people dare not eat it. First of all, the scavenger fish is not large, the meat is very small, basically all bones, and there are not many parts to eat. The second reason is related to the feeding habits of this fish, scavengers love to eat some garbage, feces, especially in the wild environment, but also carry a lot of parasites and heavy metals exceed the standard, no one dares to eat scavengers.
It is also for these reasons that scavengers have no natural enemies in our country so far, and the environment is very suitable for their growth and reproduction, so they are flooded. However, in the northern region, you can't see scavengers, that's because the fish is afraid of cold, and the winter in the north is too cold, and the scavenger fish can't overwinter naturally.
<h1 class="pgc-h-arrow-right" data-track="19" > concluding remarks</h1>
Although the scavenger fish is now flooded in many places, there are still many people in our country who cultivate it because it is a very good ornamental fish, and some people breed it as an ornamental fish to sell. However, here we should remind everyone that if you buy a scavenger for ornamental fish farming, do not release it into the wild, let alone buy a scavenger to release it, which must be remembered.
Even if you catch and catch scavenger fish in the wild, don't release it, directly solve it on the spot, this is also for the people to eliminate harm. Imagine eating 5,000 fish eggs a day, how many baby fish will be bred? They are a disaster for some fish!
