Many anglers have the habit of giving fish to others, and if they catch a lot of fish, they don't want to eat it or can't finish it, so they either put it all back in the river or take it home to give it to relatives or friends.
Wild fish caught in the river may not be able to be bought with money in normal times, and the price is more expensive than farmed fish, as long as you are willing to give it away, few people will refuse, and it is not good to pick it up in vain than to buy it out of pocket.
But there is such a kind of fish, you just give it away for nothing and no one wants no one to eat it, and the cat "shakes its head" when it sees it, it is - scavenger fish.
Speaking of scavengers, those who don't know much about fish may be unfamiliar because they are not native to the mainland and are now flooded in many parts of the south.
I heard a fishing friend in Guangdong say that the rivers on their side, whether they are big rivers or small ditches, can catch scavengers everywhere, and the number is so large that they can't be fished at all, and they angrily accuse who put these invasive alien species into the river, which is simply not a human thing!
Scavenger scientific name mouth catfish, also known as sucker fish, anglerfish, etc., is native to the Amazon River basin and Central and South America, is an invasive alien species.
At first, the scavenger was kept in a fish tank by aquarium enthusiasts, don't get me wrong, it is not an ornamental fish, the purpose of putting the fish tank is to allow it to clean the fish tank, eat the leftover food and feces of other fish, and play a role in cleaning and purifying the water quality of the fish tank.
From this point of view, people will say that this is still a beneficial fish, but you are wrong to think so, its benefits are limited to the fish tank, once it reaches the natural waters, it will become a huge hazard!
The scavenger has very low requirements for the water quality and food of survival, the polluted water quality can survive, almost all of the people who can eat and can't eat are not refused, a pumpkin thrown into the water can give you nothing left, it also has a great harm, that is, it will eat the eggs laid by other fish.
Many invasive alien species, no one eats them in their place of origin, but when it comes to our country, the treatment is different, and it is not enough for everyone to eat, such as crayfish, bullfrogs, rabbits, etc., which is not artificially bred to meet the market demand.
But the scavenger really no one eats it, in addition to the unpalatable itself, the scavenger's whole body is wrapped in a hard shell, a fish weighing one or two catties, the shell is removed and disposed of less than two taels of fish meat, and its shell is very hard, it is difficult to cut with a knife!
There are also many people in China who have tried to eat scavengers, including Xiaobian, but I gave up after eating it once, the point is that its meat is really not delicious, no matter what method is used to cook it, it is difficult to swallow, to put it bluntly, it is fish, but there is no taste of fish at all.
The scavenger has no animal to threaten in natural waters, birds and carnivorous fish cannot eat at all, and in just a few years it has become the new overlord in many southern waters, not only competing with native fish for food, but also eating their eggs, which is quite harmful to the mainland's fisheries and ecology.
The most serious scavenger infestation is in Guangdong Province, for which the local authorities have also carried out some fishing activities to eliminate the scavengers, but the effect is not obvious, because most of the natural waters are interconnected and cannot be completely cleaned, and it will not be long before they will resurge.
I often see some fishing friends, after catching a scavenger, they will throw it on the shore, or shoot it to death, at this time, some unknown "hypocrites" will say that this practice is very cruel and does not love animals!
In fact, this method of dealing with it is the most correct, and letting it go is creating evil! The state has also introduced measures to control invasive alien species, and has listed scavengers as harmful invasive species, and no matter whether you catch them or catch them, they can no longer be released.
Write at the end:
Personally, I think that the overflow of scavenger fish is inseparable from the people who want to release the fish, and I often see some people in life, under the banner of "doing good deeds and accumulating virtues", regardless of good or bad, put those alien invasive species into natural waters, which is the reason for the "flooding" of scavengers and some alien harmful species!
