When I was a kid growing up, I lived in a town in southwest Ohio, and the Great Miami River ran right past my town; back then, every paper mill, and every business near the river dumped their chemicals, and anything they didn't want in the river; the only fish that could survive in such polluted water were catfish and carp. We used to catch them just for the fun of it; (always threw them back, btw) We always used doughballs for bait; making doughballs is a bit of an "art"; (I was never worth a nickle at it) As I remember, you just start with plain white bread, get it slightly wet, and keep "working" it with your hands, adding small amounts of water as needed; when you get the dough nice and "doughy", put it on a hook, then let it hang in some boiling water for a few seconds; this makes it much tougher, causing it to stay on the hook much better. Carp will bite on just about anything, but doughballs are the best bait to use. BTW, you were asking, "how to catch carp".............just the opposite of catching a bass; carp are called "bottom feeders"........they don't "grab" prey like a bass does; they swim very slow, right on the bottom, and when they find something to eat, they just kind "suck" it into their mouth; catching them requires a lot of patience; when you first "feel" them taking the bait, you wait for a few seconds, then draw back on the rod, setting the hook very slowly, very "gently"; you really need them to swallow the dougball and hook; if you try to set the hook before they swallow the bait, their mouth parts are very soft, and won't hold the hook. And forget using bobbers; carp get 90% of their food on the bottom; even more so than catfish.
My brother-in-law was 18 yrs older than me, and was kinda like a big brother; used to take me fishing and rabbit hunting when I was still maybe 10 yrs old; he always fished for catfish; he always made jokes about "certain people" who ate the carp they caught; used to say, the BEST way to cook, prepare a carp...........get several fresh "cow pies", lay the carp on a board, pack the "cow-pies" all around the carp, then stick it all in the oven for an hour or so; then take it out, pick away all the "cow-pies", and throw it, PLUS the carp, in the garbage can, and eat the board. ( season to taste, plus add ketsup )
When I was 10 years old, I thought this was the funniest thing ever ! (but that was 70 yrs ago, and I doubt if many will see the humor now !) (My, how times have changed !)
