I was just taken to a pond by a friend who had stocked it he thought with channel cat but we now know he got flatheads instead the fish have been in here for about 6-7 years and are all (from what we saw) 4-6 pounds. I have never fished for flats and need to know what is the best bait and set up for caughting them in this still water. We feel that some need removed to allow for the growth of what is left. I need started with the basics. the pond is about 1 1/2 acres and he put 200 in. how many do you think should be taken to let the big boy grow up.
