LakeL :

Not sure just what you are looking for. A couple of points. Not all LMB will grow to 7-10# only a % have what it takes (genes, food , luck, time etc.)to get there. Mostly females so that knocks out most all the 50% that are males. A higher % of your first stocked LMB will live to old age assuming they were added into a pond with a good forage base and water quality and no predators larger than them and the water quality and forage stay good. All generations after that have large % losses due to predation by most things in the pond at one time or another along the way. Stress of all kinds, including being caught and released, will reduce the % survival. Summer is the worst time for stress in hot water in the south. There are a number of ways to interpret your question on morts.; as in, if fewer live then the chance of the rest getting big without competition is greater or morts. on the next generations effecting the original stockers. So I will stop here and let you ask about what I have not answered and then I will try again.

One thing is sure, in order to get the normal pond to produce large LMB you will have to harvest LMB unless you intend on constantly stocking additional forage of the right size. If you intend on stocking like that you will have to watch for stress related to carrying capacity and DO problems.
