Common catfish are catfish (native catfish), catfish with big mouth, catfish with beard and catfish with fur beard (catfish with Egyptian beard).
Catfish has four beards and has poor eyesight. It senses taste through four beards. In fact, there were six when I was a child, and then one pair degenerated.
In ancient times, primitive people ate this easy-to-grasp high-protein thing to develop brain capacity as big as ours, and let human beings dominate the earth.
Catfish is slippery, isn't it difficult to catch? If they live in clear rivers and lakes, it is difficult to catch them, but this catfish just likes to live in a small pond full of mud, and there are a lot of them, one in each hand. I don't know how many times easier it is to catch than those birds and animals. As for the problem of parasites in raw food, leave him alone. Anyway, people's life span was short at that time, and not every fish had parasites. Let's talk about killing parasites with fire after eating long brains. In order to live a better life, there are always necessary sacrifices.
After primitive people eat catfish, let's talk about how we eat catfish.
Catfish is rich in nutrition. Every 100g fish contains 64. 1g and protein 14.4g, and contains various minerals and trace elements. The taste is as wonderful as the nutritional value.
Many people say: catfish is dirty. Yes, it has strong adaptability to the environment and can survive in the sewer. But most catfish are carnivores and need clean and open waters. Even if it's dirty, it's visceral. Just don't eat its guts. It's easy to tell if it's a clean catfish. Catfish living in smelly ponds will have a strong fishy smell, which will not be eliminated when cooked.
