? Trigonocephalus trigonocephalus is one of the unique fish species in China, and its distribution range is relatively wide. From the point of view of living environment, Trigonocephalus angularis is a kind of fish living in freshwater, which can not adapt to the life in seawater, so it belongs to freshwater fish, not marine fish. As freshwater fish, they live widely in the freshwater basins of our country. For example, in the Yangtze River, Yellow River, Heilongjiang River, Songhua River and other rivers, the number of Trigonocephalus living is relatively large. Trigonocephalus angulatus has higher requirements
for the water environment, so they are not found in all basins. First of all, they have certain requirements for the speed of flow, do not like places where the speed of water is too fast, and like to live in still water. In addition, they prefer to live in places with clean water and abundant oxygen, which is not common in fresh water with dirty water and low oxygen content. They often live at the bottom of freshwater waters where there are many aquatic plants, because there is more food for them to eat.
? It has been introduced above that triangular bream is one of the unique fish species in China. In our country, there are not only many wild Trigonocephalus bream, but also many Trigonocephalus bream under artificial breeding conditions. It is common to breed Trigonocephalus angularis artificially. Under the condition of large-scale breeding, breeders will first set up a breeding pond in a place with sufficient and clean water, and use freshwater breeding method to breed them. Trigonocephalus angulatus is also a kind of fish with high economic value, which belongs to the treasure of fish species in our country. It has high edible value and rich nutrition, so it can obtain high economic benefits by breeding them.
