Not being able to aerate isn't the end of the world. Just limits the likelihood of growing larger HSB, but I still think you could grow 6-8 pound HSB. You also run a higher risk of summer/winter kill but if you manage the pond, the risk is lower.

If you are going to feed(think higher quality 40%+ protein feed, not trash feed), then you can bump your numbers a bit. I would look at stocking 3 pounds of FHM next spring. Start sourcing the HSB now, as they will be the trickiest fish to source. In the late summer or fall, stock 300 HBG, 20-25 HSB and up to 60 CC. The number of CC is based on how many CC you think you will remove per year for the table. You can also stock 1-2 pounds of GSH, but with pellet feeding they aren't needed.
