As a country with a long food culture, China can be said to have eaten everything that can be eaten in a different way. This includes not only native food, but also some exotic species. When it comes to exotic species, we have to mention crayfish and "scavengers". Crayfish from the beginning of people to be regarded as the "killer" of the ecological environment damaged by people to become an indispensable food on the table today's deeply loved, it can be said that it is a beautiful turnaround battle; and the "scavenger" has changed from being loved by the public at the beginning to no one today. It can be said that it is more bitter than crayfish.
"Scavenger", scientific name under the mouth catfish. The earliest was introduced by China as an ornamental fish, one is because its adaptability is very strong, and has a variety of varieties, ornamental, easy to raise these three characteristics, for people who are easy to raise fish to death is a great news; the second is that it eats everything, it can be said that the comers do not refuse, and it can also clean up the residue and dirty things in the fish tank, so it has won the titles of "scavenger", "sucker fish" and so on. So it was once favored by people.
Why did the "scavengers" with so many benefits become the ones that no one cares about now?
It turns out that its good characteristics are also its fatal flaws. It has strong adaptability, so it is easy to survive everywhere, and it has a very hard shell, and it is an alien species, which can be said to have basically no natural enemies, so it can reproduce at will. Another fatal flaw is that it eats everything, not only can it clean up the dirt, it can also eat the eggs of other fish. Therefore, its flooding once caused huge economic losses to major waters across the country, seriously damaging the local ecological balance.
Of course, people certainly cannot allow it to be destroyed. Therefore, some foodies have begun to study the practice of "scavenger" fish, after all, there is an alien species of crayfish as a precedent, "scavenger" if it can appear as a delicacy in people's eyes, it should also be very popular, and incidentally solve ecological problems, which can be described as killing two birds with one stone. The result, of course, was backfire. The "scavenger" has hard bones all over his body, and the edible parts can be said to be very few. Not only that, because the "scavengers" eat garbage all year round, the number of parasites in their bodies is outrageous, and the only part of the meat that can be eaten has a rough taste and a fishy taste that is difficult to hide. This is hard for people to accept. After all, who wants to eat something that is hard to eat and easy to get sick? So even when foodies start to give up, "scavengers" start to become unattended.
Some small partners will certainly be very curious, since they have not eaten, it has not solved the problem of "scavengers" flooding, and there are no natural enemies of alien species, there should still be many, where did the "scavengers" go? It can't disappear out of thin air, right?
Now the main use of "scavengers" is two: one is ornamental value, it is sold as ornamental fish, polyculture will not harm other fish, but also clean the fish tank, in one fell swoop; the second is to break it, after fermentation into feed or fertilizer, feed to pigs or other livestock to eat, it can be said that the end is quite sad. After treatment, the "scavenger" will not retain the unpleasant fishy smell, and it is also rich in protein and calcium, and the effect is quite good.
Xiaobian feels that as an exotic species, the "scavenger" is now reduced to being used as feed by livestock, which is also quite miserable, much more bitter than the life of crayfish. It can only be said that there are not many things that can stop the pace of foodies, and the "scavenger" counts as one, of course, there is no good life. Of course, friends who like to raise fish recommend buying a "scavenger" and putting it in the fish tank, the cleaning effect will exceed your imagination.
