Silver carp is a kind of freshwater fish, and their body size is relatively large. Under normal circumstances, that is, they will not die for various reasons, the weight of silver carp can reach 30-40 kg. However, in general, silver carp can not grow so big, because their size will be affected by many factors.
For example, the body shape of farmed silver carp and wild silver carp is different. Artificial breeding of silver carp is generally used to sell, so in the breeding of about three years will be sold, can not continue to grow. Therefore, the common silver carp on the market weighs only a dozen kilograms, and the silver carp that can reach tens of kilograms will be relatively less. If the wild silver carp live in rivers, they can continue to grow and grow larger. In addition, another important factor is the degree of environmental suitability. When the environment is suitable, the size of silver carp is relatively large, and the growth rate will be faster.
Under normal circumstances, the life span of silver carp can reach 7-8 years. That is to say, without the influence of human factors, the life span of silver carp is relatively long. This is just the average life span, and some individual silver carp will live longer, up to 10 years or more. However, the life span of silver carp is generally not so long, because its life span will be affected by many factors. For example, the artificial breeding of silver carp life is generally not long, in the breeding of about 3 years may be sold, life is only about 3 years. Even silver carp living in wild environment may be affected by environmental pollution or inappropriate environmental factors, thus shortening their life span.
