There are many kinds of fish, and sea fish is one of them. They live in the sea and cannot live in fresh water. Mandarin fish is also one of the common fish in China, they do not belong to marine fish, because they can not live in the ocean, but live in fresh water, from this point of view, Mandarin fish belongs to freshwater fish. In fact, Mandarin fish is widely distributed in freshwater in China. South to China's Guangdong and Guangxi provinces, north to Heilongjiang Province rivers, lakes, ponds and other freshwater basins, there may be Mandarin fish distribution.
Mandarin fish can also be cultured artificially. They also live in fresh water and cannot live in sea water. They are also freshwater fish, not sea fish. Because Mandarin fish are edible, it is very common to breed them in captivity, and in many cases in large areas.
As mentioned above, Mandarin fish belong to freshwater fish, not marine fish, because they can not live in the ocean. As a freshwater fish, Mandarin fish can naturally survive in freshwater, and they have adapted to the freshwater environment in the long process of survival. In fact, in China's rivers and lakes, the distribution of Mandarin fish is very large, they can survive well in fresh water, but can not live in the sea. Not only wild Mandarin fish, but also cultured Mandarin fish live in fresh water, the PH value and salt content of fresh water are adaptable to Mandarin fish, and fresh water is needed for breeding, not sea water.
