Herring is a relatively common fish, belonging to freshwater fish. Among the freshwater fish species, the herring is a relatively large species. After the adult, the length of many individuals can reach 1 meter, and the larger ones can even reach nearly 2 meters. The growth rate of black carp is also relatively fast, breeding two or three years of black carp can reach about 4 kilograms, and their adult weight can reach tens of kilograms. At present, there are records of larger herrings with a length of more than 1.8 meters and a weight of more than 200 kilograms.
Of course, this very large herring is relatively rare. In addition, how big they can grow will be affected by many factors. For example, the size of wild herring and captive herring is different, and the average size of captive herring will be larger. In addition, the size of the herring is also closely related to the surrounding environment. If the herrings live in a suitable environment, their development will be relatively good, and their size will be slightly larger.
The life span of the herring is relatively not particularly long. Most herrings live between 7-8 years, a few herrings live slightly longer, can live to about 10 years, but more than 10 years of herring is still relatively small. In fact, the longevity of herring is related to many factors. For example, artificially raised herrings are generally used for sale, so their life span is generally not particularly long. Wild herring may also shorten their life span for various reasons, such as pollution of living environment and so on. In this case, the herring is easy to live, and the living time is relatively short.
