Darrell,
I would recommend no more than 25 HSBs per acre in your situation. To alleviate the added competition and encourage further LMB growth, consider removing a male LMB for every HSB that you intend to stock, then keeping good records and a keen eye on your baitfish population in the future. Male LMBs should be easy to harvest and differentiate during the months of March, April, and May. Feeding is a plus. Baitfish can be stocked as needed as well.
