I've heard since I was a kid that:
Catfish is the dirtiest fish in the world, it grew up eating, don't eat it!
Not only that, but the adults will tell me that farmers will directly dig the fish pond next to the pigsty, so that the pig manure and cow dung can be directly poured into the fish pond as fish food!
If this is true, it is disgusting! Why would anyone dare to eat catfish?
Welcome to the Wonders of Nature. Today we will break the rumors of those catfish one by one!
<h1 class="pgc-h-arrow-right" > the first question: What exactly is catfish? </h1>
Don't look at everyone's mouth about catfish, in fact, many people don't know which fish are catfish.
Like what
Hotpot restaurants sell expensive yellow fish and Qingjiang fish, which are catfish.
In the urban weird talk, the sewer monster fish that can eat people, the Catfish, is the catfish.
Cheap and tasty bassa fish in the supermarket freezer, or catfish.
Even the scavenger fish in the fish tank is still catfish.
I didn't think about it, what is hidden behind the catfish is actually a large class of fish for catfish. What they have in common is:
There are no fish scales, there is a layer of slippery mucus on the body, and a funny long beard growing around the wide and flat mouth.
Nearly one-quarter of freshwater fish are catfish. In the large category of fish, catfish also account for 1/10. This slippery family not only has many fish mouths, but also has an important position in human life.
Catfish is a very important economic fish and is one of our main food fish. There is a large amount of farming in Asia, the Americas and even Africa.
<h1 class=pgc-h-arrow-right > the second question: Do catfish really eat? </h1>
Let's start with the answer.
Some catfish do eat.
But the catfish that can be on our table basically don't eat.
In nature, animals do not particularly reject excrement. eating behavior is very common, such as dogs known for eating, and then such as shell lang who can't live without eating, eating is actually a very sparse and ordinary behavior.
But since it's food, it doesn't matter if we mind.
In catfish, there are indeed many catfish are scavengers, usually inhabiting the bottom of the water, relying on a large mouth to rummage through the nutrient-filled humus at the bottom of the water, which is an important reason why many people think that catfish eat. For example, Clarias gariepinus, the sharp-toothed catfish that was introduced to China a few years ago, is also the legendary pit catfish.
The catfish's home is Africa, which is dry and barren, which also exercises its strong resilience to stress. The requirements for water quality are extremely low, and it can survive in shallow mud and even crawl on dry ground.
Relying on the habit of not being picky eaters, being able to hunt and eat the corpses of other creatures, and even excrement, those sharp-tongued catfish that escape from human farms have become regular customers of urban sewers and sewage tanks once they are in human cities. Coupled with the fact that they still look black on the back, it is no wonder that people have misunderstood.
In fact, the sharp-toothed catfish that survive in this environment are of extremely poor quality and are not brought to the table at all. As for the farm, it will not save costs and deliberately make the breeding environment too poor, after all, once a large area of infectious diseases is generated, it will be more than worth the loss.
<h1 class="pgc-h-arrow-right" > the third question: Is the catfish dirty and can it be eaten? </h1>
Strictly speaking, the catfish is really not a clean fish. But this does not represent all catfish.
Catfish often used for consumption in China do not have such a rebellious resistance to nature, and the living environment must be clear water, otherwise it will burp without a word. For example, the common flower catfish Silurus asotus and largemouth catfish silurus meridionalis are like this, and for example, the name is with the noble Qingjiang fish, which is directly based on the clear water quality of the breeding environment, and it will not be the so-called dirty water fish farming!
As for the sharp-toothed catfish, because of its fishy taste and poor taste, it has long been eliminated from the market, and it is difficult to eat it in the market! So feel free to eat boldly
