You WILL have to harvest some of the bass once they start to spawn. I wouldn't add any more LMB, in fact, if I could catch that one, I'd take it out. Instead of adding LMB I'd add HSB. With only SMB in there your forage fish might stand a chance of producing enough YOY for feed for the SMB and CC. I'd keep a record of the length/weight of any of the SMB that you catch. If their relative weight starts to decrease, then you will need to add more forage fish.
