Take the remains of a catch from before and put it into a plastic garbage bag and the freeze it. When you go out the next time take the bag still frozen with you and empty the remains into the water where you want to fish at in a couple of hours. Also if you use chicken livers put them onto a disposable plastic plate, heat them up from 1min 30sec to 2 min covered with a paper towel. Put them back in the tub and you will have some of the toughest livers, and smelliest catfish lip smackin liversyou can not hardly throw off your hook!
