First stocking can produce best size, yes, if proper forage is present.
If Proper habitat is present I would think you would see some sort of continued representation of BCP. If only a few make it to a size such that they escape predation, they will/should grow if proper food (size and quantity) is available.
If you're seeing fish max out at 8-9" and not many of them, my opinion is they don't have suitable forage and are likely a source of food for other species. Maybe water clarity is not as good as it was in the beginning??
When I said "something was present that isn't now", I meant some condition or multiple of is different.
If you don't have an abundance of sunfish of any species present, I'm going to say they are being utilized heavily-by something.
There is an element present that we aren't seeing or isn't standing out readily visible.
It could be water quality isn't optimum, but I think it's lower in the food chain where the issue is, but why?
Some WR's of everything you can sample would be a great help in starting to figure something out.
Maybe the Guru's have something to add that I'm not seeing.
