Red crucian carp is a species that can be cultured artificially. Before breeding, we can know their size first. They are a relatively heavy fish in terms of weight. Generally speaking, the body weight of red crucian carp about one year old will be about 50 grams, the weight of red crucian carp about two years old will be between 250 and 300 grams, and the weight of red carp about three years old will be between 250 and 300 grams. After adulthood, the weight of wild red crucian carp is different from that of cultured red crucian carp.
If they are wild, they will weigh 300-400 grams when they grow up. If they are cultured artificially, their adult weight will be between 500-600 grams, which is generally larger than that of wild red crucian carp, because the food nutrition provided by artificial breeding is more. In addition, in terms of length, their body length will be about 30 centimeters after adulthood. If they are raised in families and do not provide enough space, their bodies will be shorter.
The life span of the red crucian carp is relatively long. However, the wild species are not quite the same as the cultivated species. The red crucian carp of wild species will live for about 15 years, but the red crucian carp of artificial breeding species will have a shorter life span of about 10 years. However, how long they can live depends on whether the surrounding environment is suitable. If wild species of red crucian carp live in polluted waters, then their life expectancy is short. Artificial breeding varieties of red crucian carp are more sensitive to the surrounding environmental factors, if the environment is not suitable, their life span will be shorter, if sick, it is easier to die.
