That submerged white rock is being used by the carp in this pond to rub their sides. As they swim by they turn on their sides and give themselves a good little scratch. I’ve dubbed it “Rub Rock.”
I was pheasant hunting along the shore of Banks lake when I saw some activity along the shore line.
As I stood and watched. This group of carp, five or six of them were working the shore line turning rocks and getting after the crawfish.
Team work
Launched onto dead calm water at sunrise yesterday out of Potholes state park. There were literally hundreds of carp everywhere, cruising slowly or just suspending in place in small groups with their snouts out of the water. No apparent mouth movements, so if they were feeding, you couldn't tell by me. I dropped big bugs and small bugs right into the middle of them and in their paths if they were moving, but they ignored them. I could get the kayak within 5 ft before they spooked.
Any idea what they were doing? A few jumpers around, also. I wonder if the decreased algae bloom this year has the oxygen levels down and they were getting air?
