Catfish is a very common fish, which is distributed all over the world, and they are also widely distributed in China. Catfish can live in the wild or be farmed. Under normal circumstances, catfish's life span is very long, they can live to about 70 years old. Some catfish live longer, to about 100 years.
However, catfish with such a long life span are rare. Catfish in daily life generally cannot live for such a long time. This is because there are many factors that can affect the life span of catfish. For example, catfish raised in captivity naturally do not survive for such a long time, they will be sold after a few years of breeding, catfish is a common ingredient. Therefore, the life span of these catfish is only a few years. The life span of wild catfish is relatively long, sometimes up to decades, but there are also many factors that shorten its life span, such as the environment is not suitable, such as human hunting and so on, will affect its life span to varying degrees.
Catfish can reproduce and spawn, but only when they reach the right age and the environment is suitable. First of all, catfish need to meet the age conditions, that is to say, catfish can only reproduce after sexual maturity, and catfish in the juvenile stage can not reproduce and spawn naturally. Specifically, catfish probably entered the stage of sexual maturity at about 2 years old, relatively early. Catfish at the stage of sexual maturity will breed and spawn in the appropriate breeding season, specifically from April to September, and the peak period is May-July, because the water temperature is the most suitable at this time.
