The genetics are not getting better. The average size is increasing because more are put back to live longer. If you only want to consider data that promotes your viewpoint then go ahead. That is not a discussion, that is a lecture. I understand your love of giant bluegill and why you want to see them everywhere, but for many people the primary value in panfish is as food, not as trophies. Maybe your work in developing trophy ponds will start to change that.
