Grass carp is a kind of common freshwater fish, which is widely distributed in all parts of China. Grass carp are distributed in many rivers and lakes, and they belong to wild grass carp. In addition, there are also grass carp under artificial feeding conditions, they are mainly used as economic fish, grass carp is edible, and is a common food.
The growth rate of grass carp is different in different environments. For example, the growth rate of wild grass carp is slower than that of grass carp in captivity. Artificial feeding, can artificially control the surrounding environment, so that various factors are in a suitable state, but also to provide adequate food for grass carp. In this case, the growth rate of grass carp is relatively fast. If grass carp live in the wild, they may encounter inappropriate or inadequate environment, at which time their growth rate will be slower. In addition, in different age stages, the growth rate of grass carp is also different. For example, the fastest growth stage of grass carp weight is in 2-3 years old, and then the growth rate is relatively slow.
As mentioned above, the growth rate of artificially raised grass carp is different from that of wild grass carp. Under the condition of artificial feeding, the environment is suitable, the food is sufficient, and the growth rate of grass carp is relatively fast. Generally speaking, the weight of grass carp can reach 4 kilograms after more than one year of cultivation. The weight of grass carp cultured for about two years can reach about 7 kg, which shows that the growth rate is very fast. The growth rate of wild grass carp is relatively slow, and it takes a little longer to grow to 4 kilograms.
