You might get lots of responses regarding the best flathead bait.
Flathead will eat any live fish they can catch and fit in their mouth. Nature is sometimes harsh and catfish are not afforded the luxury of choosing their meal.
But by observing their most abundant food sources we may be able to use the baits they prey on most often. Flathead obtain their meals with stealth and concealment. They do not possess speed and agility to outmanuver baitfish. Small carp and panfish are slower fish that live shallow in submerged timber that can be used for ambush.
Goldfish are an excellent choice because of their strength and endurance. They remain active and present an image of a small carp. They are easy to maintain and durable after being hooked.
Slipping any lively baitfish into the Scioto river can produce large flathead.
Finding good access to prime angling spots gets more difficult every year.
I hope you keep searching and find many trophy cats along the way.
