I think flatheads are good to eat no matter what size. They lay around alot and eat live fish. I have, in the past, eat them up to 35lbs. Me and most of my friends and family turn loose most flatheads over 10lbs. Smaller than 10 are easier to clean and we catch plenty under 10. We release bigger fish trying to catch a really large fish. I would like to think I have caught this fish at least once before! lol. A 25lb fish will never get bigger if filleted!!
