I filet the ribs out with the backbone, all in one piece, working with the fish on its back, head and tail off. Seems ass backwards to the way most people do it, but it works for me. I leave the radial bones in, but if I'm smoking the fish, I'll pull them out with needlenose pliers after I smoke the fish. I like to get them out before vacuum packing smoked fish so they don't puncture the seal.
