Do Fish Feel
Pain? LaDon

Pain is transmitted by specific neural pathways and
receptors for pain may be activated by mechanical, thermal, or chemical stimuli.
Fish possess these types of receptors in their skin. In humans, pain is sent to
higher brain centers (prefrontal cortex) where it is perceived and the
perception is associated with a powerful emotional experience. Fish, however, do
not possess these well developed higher brain centers and thus they probably
perceive a painful stimulus and react to it almost as a reflex. After the
initial perception, they would not be bothered by the stimulus, similar to what
occurs in humans who have had surgery to central brain regions to treat chronic
pain.
