Catfish is a common fish that can be eaten. The size of catfish is still relatively large. But farmed catfish are generally small, weighing less than 10 kilograms, because they are sold after a few years and can no longer grow. Catfish in the wild are relatively large because they grow all the time in the wild. If there is no human interference, catfish can grow very large, the largest recorded catfish weight can reach more than 200 kilograms, close to 300 kilograms.
There are several factors that affect the size of a catfish. For example, catfish are widely distributed all over the world, and they have many different species, and the size of these different species is different. Some catfish are small in size. For example, there is a catfish called "mountain catfish", which is only 30-35 centimeters long after growing up, and weighs only about 4 or 5 kilograms. For example, there is a kind of catfish living in the Mekong River Basin called "man-eating catfish", their size is relatively large, the average weight of adults can reach more than 100 kilograms. It can be seen that the differences between different varieties are relatively large.
Catfish can reproduce, but some conditions need to be met. Among them, the most important condition is age, because catfish can not reproduce when they are very young, only after sexual maturity can they reproduce. The age of catfish sexual maturity is relatively early, generally speaking, about 2 years old has the ability to reproduce. After sexual maturity, catfish will breed when the water temperature is suitable, and the water temperature should be at least stable at about 18 degrees.
