That makes pretty good sense. I'm sold on the concept that pure strain bluegill will overpopulate their foodsource if not managed. I'm thinking about an experiment that would involve several different species but I'm not sure how to set it up yet. If I try it I'll post the project in it's stages to see how it develops.
One more round of questions. Is the Georgia Giant a just a hyped up HBG or is it a different type of hybrid? I have heard that they will stunt after about 3 generations. Can this be avoided if you add new specimens each year or is it genetic?
