It's a common belief that the silt on the back of wintering flatheads is from their non movement through out the wintering months. In my opinion this video will show that this isn't true!
very cool video, i watched an in-fisherman episode once when they were jigging for flatheads with large jigs and spoons in the winter time when they were schooled up like this.. half were snagged have actually went ate but interesting none the less.
