Dave, you are absolutely right, when we intensively do anything in life, we can do so much more than we ever thought we could.
I'm guessing that I manage our lake less than many people on this forum. We do have two Stren feeders, each to go off for one second in the morning and evening. This doesn't come close to providing all of the food needed and is completely supplemental. After that, I try to add 20% of subadult fish every year. The CC are 5-15 pounds and I will just let them die out to make room for other species. Everything is catch and release and that's all of the management I do.
Back to Todd's question. One form of management is to use only LMB or SMB in a lake. To do this, we harvest small fish (say 10-12 or 14 inches) as panfish. This allows some fish to get bigger and keep the population of smaller fish from stunting. For someone that doesn't or can't manage their lake, this is a very realistic option.
