Crucian carp is a relatively small fish, and their growth rate is not particularly fast. Wild crucian carp lives in rivers, ponds, lakes and other waters, and crucian carp can also be cultured artificially, also living in fresh water, generally in aquaculture ponds. The growth rate of wild crucian carp and cultured crucian carp is different, so the time it takes to grow up is also different. The growth rate of wild crucian carp is slower, generally speaking, it can grow to 100-150 grams after one year and 200 grams after one and a half years. There are also large crucian carp with a relatively large size and a weight of 1 kilogram, but it takes 5-10 years for wild crucian carp to reach a weight of more than 1 kilogram.
The growth rate of artificially cultured crucian carp is relatively fast, and it can reach more than 200 grams in about half a year. At this time, the breeders may choose to let them go on the market, at this time they can not continue to grow, so that the crucian carp can be considered to grow up. For example, many breeders choose to put it in May and go public around December.
Crucian carp can carry out the process of reproduction, but the first condition to be met is the age condition. Crucian carp can only reproduce and spawn after sexual maturity, and too small crucian carp cannot carry out the process of reproduction. Crucian carp sexual maturity age is relatively early, in 1-2 years of age when they can reproduce and spawn. Some precocious crucian carp can reproduce and spawn at about 1 year old, and late-maturing crucian carp basically has the ability to reproduce and spawn at about 2 years old.
