Fish have neuro receptors such as axons and dendrites that feel sensation. The first neuroscience studies were done with molluscs which have a very simple nervous system and they definitely react to stimuli. When I was in school we did experiments with frog legs and would inject curare which is a tranquilizer at the nerve receptors to slow down reaction to stimuli and then we would measure end plate potentials. These tests were a repetition of some of the first scientific experiments published in neuroscience journals more than a half century ago. Most developed animals have a central nervous system and simpler organisms have only localized nervous systems. I'm sure fish feel something when affected by stimuli but they process it differently than we do and typically have a very simple central nervous system. In other words they react to stimuli but maybe don't think ouch they way we do. My opinion is since cold blooded creatures like carp don't feel temperature they probably don't feel pain as we feel it either. However I agree with tadpole. Any scientific study that comes out in a book form and not first as a paper in a scientific journal that is reviewed by peers can not be trusted.
So I dont trust any book thats even been written of the subject of fish health, many written by people with Doctorates in veteranary science why then did they write books, this seems to be what your saying Kieth just because Meyer couldnt locate the reaserch papers online does not mean they arent out there, the internet is just one media we chose to float ideas on isnt it ?.
Any creature will react to temperature be they carp or humans at the extremes of which we die at both ends of the scale , we find its the same for every living creature exept for extremeophiles who seem able to survive both extremes of heat and cold .
By releasing it to book form she is simply using that form of media to open debate, which in my mind she has successfully done yet as a research fellow she must have published papers .
Googling her name and asking the right questions seems to link into her the more you look, this is what I found in a few minutes of searching :-

We care passionately about the welfare of our koi, we came here to help other fish keepers in an amature capacity to help others learn and educate themselves in the subject of fish health by doing so we continue learning ourselves.
We dont claim to be experts in our field , if thats the case we have to ask Meyer exactly why he is here ?
Is it because he wishes to help others or is it for an altereria motive i;e to help with his business, personally I hope its to help, as we would love to expand our knowledge base even further.
By buying the book and reading it we hope to understand our fish that bit better because like others have already stated weve long suspected that fish do feel pain .
The reason we buy fish health books is the same we wish to learn more about the subject of fish health thus keeping our pets alive and in the best possible health , it stands to good reason that pain is a threat to that health,
Just because we cant hear fish scream doesnt mean they are pain free (can you imagine just what it would feel like to have a large ulcer in your side and just what that is doing to your receptors)?
Fish by their very nature like many creatures hide illness for as long as they can otherwise they end up as lunch and that is a fact we cannot get around so it stands to reason they would hide any pain for as long as they possibly can yes ?
This debate is set to run on both in the hobby and in anglling circles as well as in the fishing industry of which I was once part of until ill health forced a stop to it back in 1986.
I will readily admit that way back then I never gave it a thought we caught the fish, gutted them put them on ice and delivered them to the agents who would then sell them on for consumption in our stores and fish and chip shops .
Do we give any thought to this life that was torn from its aquatic enviroment no , nor do we give it a thought about any other life we take so that we as humans can eat. (however at least in the meat trade there are thoughts as to the welfare of the animals we slaughter) we make it quick as pssible , but in this I question dont we hide behind another book ,i;e "the bible", in the good book doesnt it state that we as gods chosen are given stewardship over all living creatures to do what we wish with.
No-one questions this ( now please dont think I'm knocking the bible, I would be horrified if anyone that that).
Perhaps its because I live with pain 24/7 365 day a year that I have empathy with these creatures who knows thats maybe why I bought the book in the first place, you have to admit that its as far from my usual fish diseases books as I can get .
