In regards to the possible all male BG pond, I'd be honored to help. PM me for a personal email address if you want to correspond.
Does the pond already exist? If so, is it filled yet? I've got some out of the box ideas for pond design to facilitate a trophy bluegill fishery. I've been brainstorming all afternoon on a new pond for myself. And by brainstorming, I mean 20% chance of light sprinkles.
