Why is there salt in the composition table of silver cod?

Marine fish contain salt. Silver cod should be distributed in the Arctic Ocean and the North Pacific Ocean. This kind of fish is a deep-sea fish in cold water area, with high nutritional value, containing fat, protein and vitamins. Naked fish was originally named "silver cod" in the Japanese market, because it is very similar to cod, and its price is much more expensive than real cod. Because of its high nutritional value, it is often used to cook delicious food, which is widely distributed in all sea areas of the world. Naked fish contains a lot of fat, the skin is black or grayish black, the meat is pure white and rich in oil. The meat tastes white, thin and tender. Many countries regard silver cod as the main food fish. Its liver is rich in vitamin A and vitamin D, but another kind, commonly known as "oily fish", namely "Sparus heteromaculatus", is often used to pretend to be naked-covered fish, but its muscles and internal organs are rich in waxy oil, which will cause diarrhea if eaten too much.
