Thanks , I've seen the bigger Catfish in the Arkansas River turn yuk (fatty and rank smelling like Shad). Here on Nimrod the big Flatheads are good but most I filleted have been netted in dead of winter while water really fresh. We don't have large numbers of Flatheads so I hate cleaning real small ones, but they are better. Channels I perfer ones under 3 lbs and Blues no bigger than 5 lbs.
