They more closely resemble a northern pike. There are several ways to prepare them and all of them are good in their own right.
My grandmother learned this from an indian many years ago.
Scale the fish then fillet it off the bone.
Turn your slab meat side up (skin side down) and start at the tail section. Make incisions all the way through the meat to the skin every 1/8 in all the way across the entire fillet. It is called "Scoring". Prepare fish as you would like and the bones will fry right out.
She was an excellant pike fisherman and we spent many summers living in Canada in the mid to late 80's.
Some great recipes with pike or Chain's:
