That's great the state has agreed to come out and electroshock for you... If your goal is to grow a 10 pound bass or 2 and many 3-4 pounds, I'd remove pretty much every bass that comes in during the electroshock.
Take photos of the event and record the number, size and species of every fish that comes that you can... Then post it on here for us to evaluate. I am sure the biologist(s) that come out to do the electroshocking can give you some advice as well.
