Grass carp is a kind of freshwater fish, which is very common in China. The size of grass carp is still relatively large, their weight can reach at least 10 kg, and the weight of larger grass carp individuals can reach about 70 kg. From the length point of view, the length of grass carp can reach about 1 meter, the larger grass carp individuals can grow to more than 2 meters, and the smaller grass carp can also be close to 1 meter.
Specifically, there are many factors that affect the size of grass carp. For example, although the growth rate of cultured grass carp is relatively fast, they are usually sold at about 3 years old and can not continue to grow, so their weight is generally between 10-15 kg. Wild grass carp live in the wild, if there is no human factor, they can continue to grow, its size may be relatively large. Of course, the size of wild grass carp will also be affected by the surrounding environment. Living in a suitable environment, the growth of grass carp will be better, and their size will be larger.
Grass carp can reproduce themselves, but they need to meet certain conditions. In addition to environmental conditions, another important condition is age, because grass carp can only reproduce after sexual maturity, and female grass carp will lay eggs when the breeding season comes. Specifically, the age of sexual maturity of grass carp is 3 or 4 years old. Wild grass carp breed and spawn from April to July each year. In the process of artificial breeding of grass carp, they can also reproduce, but they also have to be sexually mature before they can reproduce. Sometimes they are precocious and can reproduce and lay eggs before they are 3 years old.
