Fish as much as you wish, but don't harvest. Watch your growth rates over the next two years. As growth rates of bass level off, and frequency of small bluegill declines, then make the decision to harvest bass. Harvest bluegill in the third year, but don't take the largest sunfish. Take the next size down. The largest bluegill help ensure you will have better growth rates of all bluegill, as well as guaranteeing you will always have broodfish sunfish to supply ever-growing bass populations.
