I cut the rib bones off with the fillet, then fillet them off the fish. It is easy with a sharp knife & my fillets knives have an inch of serated blade near the handle to not dull the edge up cutting those bones. I like Fishdocs way cuz I usually cut em up in pieces after but it looks way easier to cut em in pieces before. Don't throw away the carcass. Throw in freezer & use for crab or halibut bait
