Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Update On My Pond (Need some Advice)

If you were to add SMB I would look at harvesting some LMB.
I would also stock advanced size SMB if possible but that could be tough to locate. I wouldn't expect any recruitment from the SMB.

Also introducing some new genetics to the mix might be an idea for the LMB. You said it was bucket stocked a long time ago. Again with new genetics I would harvest some of the LMB.

That all said, it sounds like you are hitting your goals on the LMB.
