? Crucian carp is one of the common fish widely distributed in China. It has a large number and is very common in daily life. From the point of view of habits and characteristics, crucian carp belongs to freshwater fish, grows in freshwater, and all life activities are carried out in freshwater, which can not adapt to the living environment in the ocean. Crucian carp is a kind of freshwater fish with very good adaptability, which is widely distributed in all parts of China, except for the western plateau areas, and is basically found in other parts of the country, and the number is very large. They live in various forms of fresh water, such as rivers, lakes, ponds, reservoirs and so on.
Specifically, crucian carp also has certain requirements for the surrounding environment. From the point of view of the water layer, crucian carp generally inhabits the bottom of the water area, belongs to the bottom fish, moves at the bottom, and seldom comes to the water surface or the upper layer of the current. In addition, crucian carp also has relatively high requirements for the surrounding biomass. The feeding habits of crucian carp are mixed. They can eat animals and plants. They will look for places with abundant aquatic plants as their habitat, because there will be many plants and animals in such an environment, which can be used as their food. Crucian carp can also be cultured artificially. They are also freshwater fish and live in freshwater.
? It has been introduced above that crucian carp is a freshwater fish. Both wild crucian carp and cultured crucian carp live in freshwater basins and are very representative freshwater fish. The freshwater culture method is adopted for the culture of the crucian carp, and a special culture pond is established when the culture quantity is large. A sufficient amount of fresh water can be placed therein, and the crucian carp is placed therein after the sterilization step is completed. Freshwater environment has a great impact on the growth of crucian carp, so we must pay attention to the regulation of the surrounding environment, so that the water quality, water temperature and dissolved oxygen are appropriate, in order to make the growth of crucian carp better.
