From personal "research"

lol

at about age 13, I can tell you an aquarium (hatchery

) fish will grab a line tied to a worm with no hook, fight it, get the free meal, and continue to do so. Hatchery fish are no different, they are born around man and fed by man, if your thoughts on INSTINCT were true, then how come the aquarium fish (which were also derived from a wild fish) aren't so pressured after this ''study'', and never refused to eat the meal that almost cost them their life. Carp in Paylakes around the central and southern parts of the country have absolutely torn up mouths, and they continue to eat even though they get caught, we think too highly of fish sometimes, why do you think I quit going around saying how much smarter Carp are than other fish, I realized Carp are just another fish, really, if fish were humans, it wouldn't be referred to as 'species', it would be 'race', we all pretty much have the same requirements and when it comes down to it, we live the same, we try to survive.
For those that don't know, a Paylake is basically fishing + gambling + competing in a planted pond.
