Yeah! Welcome to the Big Bream Club.
Theo's answer is so good it should be archived. I'd only add the following. If you can use previous Pond Boss articles to learn to ID male vs. female bluegill, then you can put heavy harvest pressure on females. This leaves the male population intact to grow faster, with less competition for food. Then if you want to get fancy you will start to harvest male bluegill that have inferior body condition.
One of our forum members took my advice on harvesting all females (NEDOC) and he's got nearly ten inch bluegill all over the place.
