CATDOLL : CATDOLL: Is silver cod a freshwater fish? What is the difference between silver cod and cod?

Silver cod is a deep-sea fish and is a marine fish. It is rich in nutrients. What is the difference between it and the so-called "cod"? It is actually an oily fish, which is a fake cod. Oily fish is the general name for spiny-scaled snake mackerel and hetero-scaled snake mackerel. It looks similar to cod, but it is not a species. Since the fish sold on the market are all sold with heads removed and cut into pieces, it is difficult for ordinary consumers to distinguish them by appearance. Oily fish contains wax fat that cannot be digested by the human body and is difficult for the human body to digest. After some people eat it, it will accumulate in the rectum, causing diarrhea, gastrointestinal cramps and other discomforts. An experimental report shows that 20 people felt uncomfortable after eating 44 people, of which 80% had oily diarrhea, 50% had gastrointestinal cramps, 35% had headaches, and 25% had vomiting. The commercial value of oily fish is not high. It is a low-priced fish. Because of its high oil content, it is mainly used to refine industrial lubricants.
