Two habits edit

Carp lives in freshwater omnivorous fish, rich body, the water shuttle swimming posture is beautiful. The life level of crucian carp belongs to the bottom fish. In general, are swimming underwater, foraging, habitat. However, when the air and water temperatures are high, it is also necessary to swim and feed in the middle and lower layers of the water, as well as in the middle and upper layers of the water.

Adult fish are mainly plant-based feeders. As the plant feed in the water body is rich, varieties of each variety, for feeding on a wide range of surfaces. The stems, leaves, buds and fruits of vascular aquatic grasses are the favorite food of crucian carp, and in the waters with higher aquatic plants such as diamonds and lotus roots, crucian carp are most capable of obtaining a variety of rich

rich nutrients. Diatoms and some algae are also food for carp, shrimp, earthworms, young snails, insects, etc. They also love to eat.

The carp is most fertile in February to April and August to December. It is widely distributed throughout the country except for the western plateau area. Carp is very adaptable and can survive in either deep or shallow water, running or still water, high temperature water (32℃) or low temperature water (0℃). Even in the strongly alkaline waters of pH: 9, salinity up to 4.5% of Lake Dari, can still grow and reproduce.

Carp living in lakes and large reservoirs

also choose to eat and live. Especially in the shallow aquatic plants, but also their concentration, even in winter, they are greedy for grass roots, most of them do not swim to the deep water without grass for the winter.

They are encountered in the flow that is traveling, no flow, choose to eat and live. In winter, they mostly dive into the depths of the water to overwinter. [
