FISH DO NOT HAVE THE BRAIN DEVELOPMENT THAT IS NECESSARY FOR THE PSYCHOLOGICAL EXPERIENCE OF PAIN OR ANY OTHER TYPE OF AWARENESS
The experience of pain depends on functions of our complex, enlarged cerebral hemispheres. The unpleasant emotional aspect of pain is generated by specific regions of the human cerebral hemispheres, especially the frontal lobes. The functional activity of these frontal lobe regions is closely tied to the emotional aspect of pain in humans and damage of these brain regions in people eliminates the unpleasantness of pain. These regions do not exist in a fish brain. Therefore, a fish doesnt appear to have the neurological capacity to experience the unpleasant psychological aspect of pain. This point is especially important, because some opponents of fishing have argued that fish are capable of feeling pain because some of the lower, subcortical nervous system pathways important for nociception are present in fish. Obviously this argument has no validity because without the special frontal lobe regions that are essential for pain experiences, lower pathways alone cant produce this experience. The rapid, well-coordinated escape responses of a fish to nociceptive stimuli are generated automatically at brainstem and spinal cord levels but, if a fishs brainstem and spinal cord work like a humans (and it is very likely that they do) there is no awareness of neural activity occurring at these levels.
Ummm... lets just say I would not bet my right arm on that one!
If there is something we know VERY little of it is the functions of the human brain! Very recently researchers have discovered that areas they had never even suspected were capable of storing memories....
Something I have learned from psychology classes in uni, is that the brain is way more complex than we can imagine and we are FAR form understanding it accurately!
Even if the fish don't have the same brain as we do, it does not mean that they don't feel pain. The argument over fishing and fish pain is mainly that the fish's MOUTH is believed to be unsensitive to the hook peircing it. Predatory fish have adapted to eat fish, that developed pointy spines as a protection. Thus by having highly unsensitive mouths the fish can gobble up spiny fish or insects without much pain!
Something I've noticed while fishing pike (I use a paddle boat and like fishing in shallow areas where I can see the fish ), is that it is not uncommon for it to gobble up the lure (rapalas with many hooks on them) and just stay there without reacting (even when hooked)... until I start reeling in! Thats when they panick. Its probably very unhealthy for the fish though, as they get a loads of stress!
But I've seen fish react violently when a BASTARD cousin would slightly poke it with a sharp knife, and struggle less harshly when he was simply pressuring it with his fingers....
A fish will also react violently if something nips its body a little, or if burning chemicals enter its environment. When you think of it, fish live in environments with tons of rocks, plants and all sort of things they will daily have to rub against ect... so they need to feel some form of pain to know that its something biting or attacking them... not just their body leaning on a leaf or rock.
