yeeesh, how is asking questions belittling their catching of good sized fish? they obviously found the spot where the big ones hang out and eat. nothing wrong with that. like to know the spot my self but likely wouldn't do any good b/c i don't fish with hardware/bait. no question they know how and where to catch fish and are good at it.
however, questioning how a fish that grew to an adult being hand fed can be the world record for largest rainbow is not belittling their accomplishment. why not, as hydropsyche says, simply grow some fish in a closed envirnment then when they are very large throw them into a lake and then start catching them (assuming they would grow large enough). would that be any different?
equating catching trout in the bow (or wherever) that descended from fish stocked decades years ago with catching a brood fish that escaped as an adult and bulked up from there is as the saying goes apples and oranges boys. apples and oranges.
