In other words you sent an email. Big whoop.
In the day that was fairly difficult for me. Especially since I was on
a PC and the Internet was on a separate Unix LAN inside of [name of

I don't know any such thing and neither do you. Anyone who claims
to know that fish can feel stress is full of it. Maybe they do,
maybe they don't, but you are not a fish, so you cannot possibly
know one way or the other.
I really wish you'd just go with the debate and not get so personal.
This is stated as knowledge in almost all C&R Data, data you've
probably cited. I've included one below.
However, I specifically did NOT say anything about the fish feeling
stress. That would be a completely different or subsequent point to
discuss.
Let's try it from this 'fact?' (it really is true Ken)...
1. Fish die when they are stressed. (Socrates)
2. Does it matter? (Plato)
3. Your answer here (Ken).
4. ?
Your pal,

Here's the data I mentioned.

Key Mortality Factors
Two factors predominate when considering the causes of angled fish
mortality: the hooking location, and the degree of physiological
stress suffered by the fish.
(snip)
Physiological Stress - Exercise performed by fish during a catch
event, or caused by angler handling methods and air exposure all
create measurable physiological responses. Physiological stress in
fish has been measured by experimenters using cortisol, lactate and
respiratory gas concentrations.
Although the catch and release mortality studies reviewed do not show
statistical results directly correlating the degree of physiological
stress to mortality, an experiment by Ferguson and Tufts examined the
effects of artificially induced stress on rainbow trout. They
concluded that various forms of physiological stress contribute to
fish mortality (12). It is reasonable to infer that such stress also
contributes to mortality in angled fish and therefore, that
minimization of stress assists in reduction of catch and release
mortality. \
