Do fishes feel pain?
People ask me this question all the time. “Clemen, when you hook a fish, is it in pain?” Although fishes struggle once they are hooked, it is more of an unconscious reaction rather than a response to pain.
Research by an international team has told us that fishes do not have enough sensory receptors in the nerve cells to experience suffering.
Jim Rose, professor of zoology and physiology at the University of Wisconsin, who led the project, said: ‘In spite of large injections of acid or bee venom, that would cause severe pain to a human, the trout showed remarkably little effect.’ The fish also resumed normal activity after a short while.
All in all, scientists have concluded that fishes do not feel pain.
