Carp is a relatively common fish in China, and their origin is Asia. Fish can be divided into freshwater fish and marine fish according to their living environment, the difference between the two kinds of fish is that the former can only live in various freshwater basins, while the latter lives in the sea. Carp is a freshwater fish, is a native of Asia, temperate freshwater fish, like to live in warm fresh water.
To be more specific, there are many carp in ponds, lakes, rivers and other freshwater areas in Asia. Carp is also widely distributed in China, basically in all parts of the country. Especially in the fresh water with more silt at the bottom, more aquatic plants and moderate flow speed, the distribution of carp is very large. Carp originally lived in Asia, and then introduced to other continents, such as Europe, North America and so on, can be said to be widely distributed in freshwater basins all over the world. Of course, after being introduced to other continents, carp can only live in fresh water, which is a freshwater fish.
The above has been introduced, carp lives in fresh water, can not live in the sea, is a freshwater fish. Wild carp live in rivers, lakes and other fresh water, and carp can also be cultured artificially. Artificial breeding of carp does not change their attributes of freshwater fish, they can only live in fresh water, so they can only use fresh water to breed. In the process of aquaculture, attention should be paid to water temperature, water quality, oxygen content in water and other factors, so that carp can grow rapidly.
