Carp is a common freshwater fish. There are many wild carp distributed in rivers, fish ponds, and reservoirs in our country. In addition, carp can also be cultured artificially. Carp is a very fast growing fish in terms of their growth rate. However, in order to grow fast, they still need to meet certain conditions. When food is abundant and environmental factors are suitable, carp grow very fast; When food is not enough or sometimes the environment is not suitable, the growth rate of carp will be affected to a certain extent. Therefore, in general, the growth rate of cultivated carp is faster than that of wild carp, because it can artificially regulate the environment and provide sufficient food.
As mentioned above, carp grow very fast when food is abundant and the surrounding water environment is suitable. From the weight point of view, the annual weight gain of carp is between 1-4 kg. Specifically, carp living in different environments grow differently in a year. As mentioned above, the growth rate of cultured carp is generally faster, sometimes an increase of 4 kg a year; Wild carp, on the other hand, may grow more slowly because of inadequate food or unsuitable environment.
In addition, in different growth stages of carp, their weight gain rate is also different. Before the age of 5, the weight gain rate of carp is relatively fast, sometimes three or four kilograms a year. After 5 years old, although the carp will continue to grow, but the growth rate is very slow, basically can not see their growth.
