I'm in the same boat with a very small (new) pond about .2 ac.
I'm not sure its even worth the cost of trying to manage it - i'm figureing $200-$300 bucks for FHM and BG and LMB.
I'm really tepted to just drop a few minnow traps in my neighbors pond and pick out the species i dont want. I'm thinking some local creek will be good for striped dace, plus mixed breed farm pond bluegill and maybe two 8" LMB - throw it all in and see what happens.
cost - free!! and i bet i'll learn something. then the next poperty i buy will have a real pond big enough to actually manage and stock and i'll apply what i've learned.
I'm not sure you'll be happy with LMB in a pond this small. You could do single-sex LMB, though, if you really want them.
