I agree with Bill !!! In most 1 acre +- pond situations it is much easier to manage with no or very limited LMB or SMB recruitment. Here is why. If you are short LMB or SMB it is easy to control the number by adding or subtracting a few adult/advanced fingerling SMB/LMB. What you can't manage for well if at all is the rate of survival of spawning LMB or SMB. If recruitment is low for a couple years then you are ok. However it is very hard to manage when the SMB/LMB have a big recruitment year and you have 50 times more young LMB/SMB survive than you need. That happens more than most people think.
