I want to fish for some Carp and/or Buffalo.  I know hardly anything about either species other than I can see them bathing in the sun sometimes.  I know there are different species of carp, I don't know which species it is I am after, but they are all in oxbow lakes if that helps.

corn on a big hook and heavy tackle.  Or just a big hook on a rod you can cast well  .  Bows work really good too

Mix up some doughballs and make sure that you put LOTS of garlic powder in them. I used to catch many, many carp when I was a kid using that stuff!

Corn or simple whitebread on a sturdy #6 hook or treble.  You can add sttrawberry jello to either and it helps.  Put it on a carolina type rig ona flat where you see them rooting and wait on it.

Also, where legal, creamed corn makes a great chum.  You either just poke holes in the can or mix it with sand and spread that around where you plan to fish for a few days beforehand.
