Catfish, also known as pond lice fish, is a kind of raw fish. This fish is characterized by no scales, a lot of mucus on the surface, a flat head and a wide mouth, and four beards on the upper and lower jaws. Catfish is not only as nutritious as other fish, but also has tender meat, delicious taste, rich flavor, less thorns and easy digestion, which is especially suitable for the elderly and children. In the eyes of China people, word of mouth has always been very good. The ancients once said: Catfish is a good supplement, rich in nutrients such as protein and minerals, especially suitable for people who are weak, weak and malnourished. It is often eaten to nourish and beautify the face, and when eaten by lying-in women, it has the magical effect of promoting breastfeeding and reducing breastfeeding.
Catfish is a miscellaneous animal. Its main foods include aquatic insects, organic debris and other creatures, such as eat small fish and mice. It even eats the bodies of its own kind when it is not full. However, because catfish is an omnivore, it has strong vitality and can live freely in polluted water. Even in some sewage containing chicken manure and pig manure, they can survive and grow fat and beautiful meat.
In fact, in aquaculture, animal manure is a very cheap, pure natural and non-toxic fertilizer, which provides a lot of nutrition for plankton in water. Therefore, many farmers use chicken and pig manure as feed. However, in the actual production process, feces contain a large number of parasites and pathogenic bacteria, which can not be directly poured into the pond, which will affect the health and safety of fish.
