? Mackerel is one of the fish living in our country. There are many species of fish, including marine fish and freshwater fish, whose living environment and body structure are quite different. Mackerel belong to freshwater fish and live in freshwater. They are not marine fish, nor can they adapt to life in the sea. The main producing area of mackerel is our country, which is found in many waters of our country. However, this fish has a very high demand for water temperature, so it is more widely distributed in tropical and subtropical waters. For example, the distribution of Lancang River, Pearl River, Minjiang River and other waters in China is very large.
Dace often inhabit the bottom and middle of freshwater waters and do not often reach the upper layers. Especially in winter, the temperature is lower than usual, and the fish's cold tolerance is not good, so they will stay at the bottom of the water in winter, basically not moving. In addition, mackerels also have food requirements. They will use phytoplankton and animals in the surrounding environment as their food, so they like to live in freshwater basins with abundant organisms. For example, there are more mackerels in places with abundant aquatic plants.
? Mackerel is a unique fish species in China, and it is also a kind of fish that can be cultured artificially. In fact, it is quite common to breed them artificially. As mentioned above, mackerel itself is a freshwater fish, so they also need to live in freshwater under artificial breeding conditions. Because of their relatively high requirements for water temperature, not only wild mackerel mainly lives in the south, but also cultured mackerel mostly lives in the south. Moreover, because their cold resistance is not good, they need to take some measures to prevent cold in winter.
