All I'm saying is people in glass houses shouldn't throw stones. Fishing is a bloodsport and fish get hurt / die and certainly get stressed as they fight on the way in.
i think you're a bit wrong there,
there's a big difference between inadvertantly killing a fish, or causing un-intentional harm to it while fishing, and what is seen in that video,
your skin could be expertly stripped while you were concious, and you'd still be alive, your guts could be removed and you'd still be watching for a short while, even you heart having stopped (removed) would still give you time to realise what was happening, ok, chances are you'd pass out long before, but you might not. Just look at the attrocities of war, people blown in half, guts across the floor, and still very much aware of their predicament.
a pal of mine had heart surgery while awake, they had to stop his heart for aprx 60 seconds while they did whatever they were doing, there were complications, and the upshot was that he watched his vital signs diminishing on the monitor for 2min40secs, at which point he passed out, thankfully he was revived shortly after that, with no ill effects, but it proves you can be 'dead' but still very aware of things.
as i said, the practice of whatever it is called, is barbaric in the least.
