Nick you once again you beat me to my comments. Channel catfish will not displace bass, it will only make the situation worse with excess predators. Sorry Big-Pond I know you wanted to hear otherwise.
Also as I said best to get trusted frineds or hire someone like me, Shan or SE POnd Mgmt. to shock them out. Sometimes as Dave and Shan mentioned the bass can be sold and reduce the shocking cost for the removal.
Shan I agree with you to a point, you surely can not make a living selling the bass, but it adds to my profit and lessens the cost to the client wanting to get rid of the bass anyway. My problem is selling them. Several years ago I could not get enough bass. Now I have tons of lakes with too many bass and no one to sell them to. I currently have 200 in my holding pond waiting to be sold that I gave money to the pondowner in hopes of selling. When I do sell them though it is a win win.
