It is a herbivorous fish that lives in rivers and lakes in plain areas. This type of animal is distributed in China, Russia, Bulgaria and other countries.

9. China’s freshwater predatory fish?

1 sea bass

Perch are usually found at the mouths of freshwater rivers. Occasionally they also forage in freshwater areas. In addition, we sometimes see them in reservoirs. However, they are rare and hard to come by. Perch are ferocious carnivorous fish with a big appetite and a strong desire to feed. They can eat 5%-12% of their body weight, especially in spring and summer. Perch grows quickly and can reach more than one meter in length.

2 Mandarin fish

Mandarin fish usually live at the bottom of the water surface. This kind of fish is very common and is distributed in most waters in China. They like to lie in still water or slow-flowing rivers and lakes, especially in shallow lakes with aquatic plants. This kind of fish has high requirements for the surrounding environment and is more sensitive. During the day, they will lie motionless at the bottom of the water and come out to look for food at night, so this kind of fish is suitable for night fishing. Mandarin fish like to make nests and live alone. When the water temperature is 15-30 degrees Celsius, its activity is still very high. When the water temperature is lower than 7 degrees Celsius, it will no longer be active. It is a typical carnivorous fish because they can prey on the fry of other fish as soon as they hatch. They like to stay in places covered by aquatic plants or blocked by rocks. Anglers can pay more attention to these places when fishing.

3. Upturned lips

The black carp is also a common fish, also known as whitefish or big whitefish. It often feeds in the middle and upper layers of flowing water or wide water areas. This fish is fast and good at jumping. It is more common in rivers and reservoirs and usually feeds on small fish. The largest one I have seen is 10 kg. The sexual maturity age of the black carp is 3 years for females and 2 years for males. The most active period is from June to August. They are used to chasing moths on the water surface. The desire to eat is strongest at night and early morning, so you can choose night fishing.

4. Blackfish

Blackfish is also known as mullet and money fish. It is distributed in all waters except the western region of my country. It is also a target fish that lure fishing prefers. Blackfish generally feed on other fish species, and young blackfish prey on some plankton. After the blackfish bites the hook again, it will burst out with amazing power, and the blackfish is the most aggressive. Generally, it will bite the hook when it sees food. The peak season for blackfish foraging is spring and autumn, and April to July is the spawning season. They will spawn in shallows with lush aquatic plants, and then male and female fish will guard their nests together. Of course, it is not recommended for everyone to go fishing for blackfish at this time. After all, we are "fishing for fishing, not for fish". It is still a bit cruel to spawn and fish for blackfish.
