My dream would be a truly trophy BG pond, but it saddens me to think that I wouldn't be able to let any LMB grow past 14-16" due to their predation on the top bluegill. But what about SMB? A 16-18" SMB wouldn't prey on your largest bluegill, and a 20" SMB would be trophy enough for me. I feel like in this way, I would get my cake and eat it too, so to speak. Trophy BG and quality SMB.
So my question to you all is if SMB will keep a BG population in control if it is just those two species in the pond with additional forage for the BG like PK shrimp and the expected snails and insect larvae.
