Carp is a common freshwater fish, their life span is very long. Carp's adaptability is very good, both cold and heat resistance, but also in the water where the oxygen content is very low, and so on, these are important reasons for their long life. Under normal circumstances, carp can live for at least 40 years. Some carp have a longer life span of about 100 years.
There are several factors that affect the longevity of carp. For example, the life span of wild carp is generally longer. Especially in the absence of human factors, their life span is generally much longer than that of cultured carp. Because carp are edible, farmed carp may be sold after a few years of farming, resulting in their life span is generally not long, only a few years. Of course, wild carp can not live for a long time, for example, sometimes carp will be killed, or their living environment is seriously polluted, etc., will affect their life span.
Carp reproduction needs to meet certain age conditions, that is, carp need to be sexually mature before reproduction. The age of sexual maturity of female and male fish is different, female fish is earlier than male fish, because female fish is sexually mature at about 2 years old, while male fish needs to be about 3 years old. Although their age of sexual maturity is still relatively early, but if artificial breeding, it is best not to choose carp too young, just entering the stage of sexual maturity, try to choose older, so that the success rate of reproduction is higher, the hatching rate of fertilized eggs is also higher.
