IMO you're wasting your money stocking anything until you get the bass numbers down. You can't keep up with overcrowded bass. You'll go broke. Take out the 1000 bass, even if it takes 2 or 3 years to get it done. Then consider building the forage. I just don't wanna see you waste all that money. 12" bass can easily eat 5" BG. Consider looking into a fyke net or funnel net to catch the bass in electroshocking won't work. However, if the bass are 12", they should be shallow come spawning season and that would be prime time to shock them up.
