Freshwater fish is a kind of fish classified according to the living environment of fish. They are two completely different kinds of fish from marine fish, and the differences between them in all aspects are relatively large. The biggest difference is that the former can only live in fresh water, while the latter lives in the ocean. From this point of view, grass carp belongs to freshwater fish, and is a very typical freshwater fish, grass carp belongs to one of the "four major domestic fish" in China, is a very famous fish, more common in daily life.
Specifically, the distribution of grass carp in all parts of China is very extensive. Grass carp can be seen in freshwater basins in plain areas. They are distributed in rivers, rivers and lakes, which belong to fresh water. Grass carp will be distributed in the middle and lower waters of these waters. In addition, grass carp can often be seen in places where there are more aquatic plants on the shore. When the temperature is relatively low in winter, grass carp will continue to swim to deeper parts of the water, which are relatively warm, and they will spend the winter in these places.
The above has been introduced, grass carp is a freshwater fish, not a marine fish. In their long history of existence, they have lived in fresh water, so they have fully adapted to the freshwater environment. The marine environment is quite different from that of freshwater, especially in terms of salinity. If grass carp live in the ocean, then grass carp may be unable to adapt to sudden changes in the environment, and may even die. Therefore, grass carp can not survive in the sea.
