Lately ive been doing pretty good catching keeper perch. But my problem is if its not really cold the perch dont freeze and die on the ice. So when I am cleaning them later when i get home there are always a few that are still kickin pretty good. I've cleaned them when they are still floppin around and it sucks, they throw slime and guts all over. any suggestions on how to knock them out or disable them without cutting the heads off? I use the heads as a hand hold when cleaning them. Thanks for any insite.
