Well, it appears to me to be word choice. Rose choses to believe fish do not expereince pain and suffering, therefore they
can't'. Chandroo et al. details a fair amount of evidence, and say that fish are
more likely than not (to feel pain and suffering).
You cannot make a decision based on Rose's confident wording, and the more tentative wording of the other articles. In fact, because of the evidence of the other articles, isn't it fair to put Rose's confidence to question? How can he be so sure? If he has further definative evidence, why hasn't it been brought to light?
The more tentative word choices are because the answer is not definative, and they are basing their decisions on what they consider the best evidence they have at hand. New evidence may be just a single experiment away.
Teelie, I am not trying to insult you, just pointing out that you seemed unwilling to accept that there is evidence to support the fish feels pain position.
... I think it should be pointed out that several of you are taking the opposite point of assuming fish have the ability to feel pain even though there's so far no proof for it.
And that was after I posted the Oidtmann and Hoffmann article that also concluded that fish have the ability to feel pain.
I doubt that there will ever be conclusive proof, simply because we, as humans, have to interpret fish behavior. They cannot communicate directly with us what they are experiencing. That, however, should not prevent us from
attempting to interpret their behavior.
You are free to believe either position, I am just pointing out that compelling evidence supports either side.
