|Carp schooling in the shallows below the dam|
I've met a few purists, fly fishermen mostly, who disdain fishing for carp. A traditional and dependable carp bait is canned corn. I came across this in my online research: dough balls (exactly what they are I'm not sure —bread?) are good carp bait. On an interesting note, one fellow was convinced that dough balls exposed to his wife's feminine "hormones" were the best carp bait of all. The person relating this bit of fishing lore went on to say that even though the man's wife did not like carp she liked him enough to provide this specialized service [source].
Probably just another fish story!
