Catfish hibernate, and it is easy to get sick when raised. Experts suggest releasing them.

Professor Yao, director of the Research Center for Fishery Resources and Environment of Southwest University, said that wild catfish can live for 60 years in general, and this catfish should be 20 to 30 years old according to its weight, which is in its prime.

According to Yao's analysis, the weather turns cold at present, which coincides with the nutritional supplement period of catfish before hibernation. Catfish, which used to lurk in rivers and caves, increased their activity appropriately and easily became fishermen's trophies. It will hibernate soon, and the wild adult catfish lacks domestication experience, so it is difficult for artificial breeding to achieve similar conditions to its wild living environment, and it is easy to get sick. Even if you don't get sick, your life cycle will be shortened because you are often affected by external stimuli. The best way to protect it is to release it in pristine waters.
