Grass carp is a kind of freshwater fish that grows relatively fast. In terms of the growth rate of their body length, the growth rate is the fastest in the first and second years. Generally speaking, the length of grass carp of 10 centimeters can increase by 20-30 centimeters after one year. Specifically, the living environment of grass carp is different, and the growth rate is also different. In a suitable environment, grass carp grow faster, and can grow up to about 30 centimeters after a year. On the contrary, if the environment is not suitable, the speed of increase is relatively slow, which can increase by about 20 centimeters a year, or even less than 20 centimeters.
Relatively speaking, the growth rate of artificially raised grass carp will be faster, because they can eat more abundant food, and more nutrition, and the surrounding environment is more suitable. In the first and second years of their growth, their body length will increase faster, increasing by 30 centimeters or more every year.
As described above, the grass carp can increase in length by 20-30 centimeters after one year. Therefore, the body length of grass carp in that year ranged from 30 to 40 centimeters. The specific situation depends on the surrounding environment and food and other factors. On the premise that the environment is suitable for the growth of grass carp and there is sufficient food, grass carp naturally grow larger. Grass carp in the current year and the second year of the body length increase rate is the fastest, in the second year can also increase 20-30 cm, will continue to grow after, but the rate of increase in body length will slow down.
