I used to make two or three trips to Dale Hollow Tenn. every fall and we would string a seine across a boat slip with a rock in the middle of the seine to hold the center down.. the edge of the seine would be just a couple of inches above the water. we then would hang a bright light over the center of the seine and leave it over night.. every morning there would be a couple dozen shad in the net...great bait for big crappie and smallmouth.. we would also hang lanterns over the side of our docked boat at night and bring in big schools of shad then snag the little shad with a small treble hook and then let the shad sink down below the school and catch big crappie about 10 or 15 feet below the school of shad
