RE: catfish bait..
If your waters are teaming with catfish and you want a hog...I'd throw out a large shiner. I was fishing a couple of years ago for bass. I tossed out a big ole shiner and caught a nice 37 " Blue catfish. I gave it away. I didn't have a scales but wiould estimate it to be about 20 pounds. I've caught many nice ones on minnows as well.and minnows are much cheaper. But the big boys...love big shiners.
