Freshwater fish and marine fish are two kinds of fish that live in different environments. The former can only live in fresh water, while the latter lives in sea water. Freshwater fish and marine fish are very different, not only in their living environment, but also in their appearance and habits.
In this respect, silver carp are classified as freshwater fish because they live in fresh water. Specifically, the specific distribution of silver carp is in the fresh water of eastern Asia. In China, the distribution of silver carp is very wide, basically in all parts of the water system, the distribution of the south and north are very wide. Wild silver carp live in rivers, lakes and other basins, and they can also be cultured artificially, cultured silver carp also live in fresh water.
As mentioned above, silver carp belongs to freshwater fish. Both wild silver carp and cultured silver carp live in freshwater. Therefore, silver carp has adapted to the freshwater environment, their habits and characteristics, as well as body structure are suitable for freshwater environment. The difference between the seawater environment and the freshwater environment is very large, once the silver carp live in the seawater, it is likely to be unsuitable. For example, there is a lot of salt in the sea water, while the gills of silver carp do not have a good ability to filter salt, and they may die directly because of the high salt content. Therefore, can not use sea water to raise silver carp, can only use fresh water to raise.
