It pains me to read the above. If you don't want to eat it, why not just put it back? It's one thing if it is an invasive species, but chain pickerel are a native fish. Even if they aren't and you want to kill them to remove them from the local lake don't throw them back in the lake. Conservation of aquatic ecosystems has moved on since the 1950's.

To answer your question, there are a myriad of ways to prepare pike or chain pickerel. YouTube has several videos on how to debone them. I eat pike regularly and they are fantastic table fare.
