I agree, even a fish that is not overly prolific like RES still needs some control of their numbers. If you stock them into a smaller pond, say 1/4 or 1/3 of an acre. Just one LMB may be all that is needed.
No need to stock FHM of GSH. Just the RES and the lone LMB. When the LMB gets over 12" or so, remove it and replace with another 6" or so LMB.
