Students say that fish have no pain, is that right?

Fish have no pain. Recent research by American scientists shows that the brains of fish have not evolved to the point where they can feel pain and fear, so people don't have to worry about their pain in the process of killing fish.

Dr James, 60, is an expert in zoology and physiology in Wyoming, USA, specializing in neurological research. In the past 15 years, James has been devoted to studying the response of animals to stimulation and pain. Recently, he published an article in the American journal of Fishery Science Review, pointing out that fish have no cerebral cortex to sense pain at all.

In the past, people thought that fish would feel pain when they were killed, but Dr. James's research results suggested that the reaction of fish when they were killed was actually a conditioned response to dangerous stimuli, and they would not feel pain. It's like a person being anesthetized on the operating table. They still have physiological reactions to external stimuli, but they don't feel pain.
