after reading some of your other posts, I can't help but at least consider maybe the RBT really did steal some of the LMB growth from the last few months. Of course that may not be enough growth to make up the difference from what you think should be there.
Kind of along the lines of what I'm thinking when I say 'back to the basics.'
Maybe drop all non-native species for some period of time (Tilapia, RBT, PK Shrimp, etc.)
Also, I would think American Pond Weed would not really impede the LMB from eating as much Bluegill as they wanted.
