there was a pretty colorful coversation about this topic on the NH board a few weeks ago. I am of the belief too that either eat it or let it go. Sometimes I do get frustrated with ponds that seemed to once offer good perch, bass and crappie fishing now over run with small pickeral but I know I have seen piles of them just thrown on the ice and don't agree with that either, I like eating all kinds of fish- though short of pickling them whole have not heard or found of a good way to deal with small pickeral..
