Crucian carp is one of the common fish in our country. It has a large number and is widely distributed. It not only has a large number of wild crucian carp, but also has a large number of cultured crucian carp. When breeding them, many factors in the water environment need attention. In addition to water quality, water temperature and dissolved oxygen in water, another important aspect that needs attention is water depth. Cultured crucian carp, the water depth can be controlled between 2-4 meters, try not to be shallower than 1.5 meters.

Specifically, in different seasons, the specific requirements for water level are also different. In winter, in order to make the crucian carp survive the winter better, it is necessary to regulate the water deeper. Especially in some northern provinces, the water depth should be controlled between 3 and 4 meters to prevent them from freezing to death. In addition, another situation is to breed crucian carp in the fish tank at home. Considering the size of crucian carp, the fish tank can not be particularly small, and the water depth needs to reach at least two-thirds of the height of the fish tank, so as to provide sufficient space for the growth of crucian carp.

2. What kind of water is good

for raising crucian carp? Besides the water depth introduced above, water quality is also an important factor. Large area of crucian carp breeding, generally will use the breeding pond, before putting in the crucian carp need to prepare water. Try to disinfect the whole pond with quicklime before putting it into the water. After a week, put enough water into the breeding pond, and then expose it to the sun for a period of time before putting the crucian carp into the pond. The same is true of crucian carp farming at home. Although river and lake water are similar to the wild environment, they are not easy to get, so tap water at home can be used. Before use, it needs to be exposed to the sun or aired, and can only be used after the chlorine is removed.
