I've been out of town on a Sport Clays event. All the Crappie I catch I lay flat in the cooler on a small block of ice. Seems if you lay them down instead of tossing them in the cooler they don't flop around as much. When the body feels cold either I slide them to the side or they flop off the ice making room for another. As soon as I get home I cube ice several inches thick everything in the box to quick chill the fish. Interesting thing, when the water is real cold I caught the fish in it may take a day or more for them to die. I don't fillet till Ice cold and Stiff.
