Many junk marketing number rumors spread catfish is very dirty, because catfish everywhere, everyone may have eaten, "catfish stewed eggplant, support the old man" is still y rooted in people's hearts, such a familiar delicacy, but this is how to grow up, this contrast is very easy to cause **** feelings of anger. Rumors spread rapidly, everyone remembers the catfish rearing methods are difficult to accept, all catfish are very dirty indoctrination. In order to food safety, in order to feel comfortable, talk about catfish, do not eat dirty catfish finally became everyone's **** knowledge.

The junk marketing number also got a picture with the truth, the photo of the catfish surfaced, greatly open mouth. Who says opening their mouths is about eating feces? We are tired of running, not will be wide open mouth gasping for air? When catfish surface with their mouths open, they are angry, the water is eutrophic and lacking in oxygen, and they have to poke their heads out and open their mouths in search of oxygen, they are not eating feces.

The earthy smell of catfish has something to do with its habits, after all, this one likes to eat humus, which inevitably accumulates in the body.

Fishy and fresh taste sometimes in the difference between the hair, a lot of volatile substances of different combinations will also produce completely different effects, such as crabs, such creatures also have the characteristics of scavenging, but we do not think that kind of fishy taste unacceptable, but in the steamed out, we will all think very fresh.
