Grass carp is a kind of common fish, which is distributed in all parts of the country, and the scope of artificial breeding is also very common. Compared with other freshwater fish, grass carp is larger and grows faster. However, grass carp can live in rivers, lakes, fish ponds or aquaculture ponds, and the growth rate of grass carp under different conditions is different.
The growth and development speed of grass carp under artificial feeding conditions is relatively fast, because the surrounding environment can be adjusted artificially at this time. When the water temperature and water quality are not suitable, artificial adjustment can be carried out at any time to keep the environment in a state suitable for the growth of grass carp. In addition, artificial feeding can provide nutritious food for grass carp every day, and promote their growth and development. Grass carp living in rivers and lakes are not like this, they sometimes grow slowly because of insufficient food or inappropriate water temperature and water quality. Sometimes the waters they live in will be polluted by sewage, which will also hinder their growth and development.
As mentioned above, in a suitable environment, the growth rate of grass carp is relatively fast. For the grass carp in captivity, the weight gain rate is the fastest when they are 2 and 3 years old. Therefore, after three years of breeding, grass carp can be considered to grow larger. After that, grass carp will continue to grow, but the growth rate of weight is slower, but at this time they are likely to be sold, unable to continue to grow. The growth rate of wild grass carp will be relatively slow, when it is about 5 years old, it can be regarded as growing up, and then the weight will not increase basically, or the growth rate will be very slow.
