? Freshwater fish and marine fish are the classification of all fish species, based on their living habits and living environment. From this point of view, bream is a freshwater fish, which lives in the freshwater basin of our country and can adapt to its life. They are not marine fish, can not adapt to the marine environment, to the sea water will appear inadaptable phenomenon, may die quickly because of inadaptability. Specifically, the main distribution basin of bream in China is the Yangtze River, and the number of bream in the middle and lower reaches is relatively large. In addition, in some affiliated lakes, there are also many bream. Besides the Yangtze River, there are also Qiantang River, Pearl River and other river basins.
Mackerel likes to live in the middle and lower layers of freshwater basins, especially in the bottom layer, where the number of mackerel is relatively large. When winter comes, the mackerel will basically come to the bottom of the water to spend the winter. They like to stay in places with more silt and lush aquatic plants, because they belong to a kind of herbivorous fish species, and their main food is all kinds of aquatic plants in the water and plant debris nearby. In addition, bream also has requirements for the flow rate of fresh water. Generally, bream lives in places where the flow rate is relatively slow. There are more bream in still water and fewer in places where the flow rate is fast.
? As mentioned above, bream belongs to freshwater fish species. In addition, bream is a kind of fish that can be raised artificially. In fact, in real life, their breeding behavior is quite common, and they are one of the representative breeding fish species in China. Many breeders choose them as cultured fish because of their high edible value and nutritional value, and they can obtain higher economic benefits. Because bream itself belongs to freshwater fish species, it is also necessary to adopt freshwater culture method in artificial culture. In the case of large-scale aquaculture, aquaculture ponds are basically needed and need to be built in places with abundant freshwater sources.
