I have a pond I raise SMB in and could easily lend itself to a grow out or forage pond. If you want details PM me and we can chat I am happy to help with what worked/failed during construction process...too much to relate here. You can probably find it in the archives, however, if you want a good laugh. Everything worked out in the end, just took a circuitous route there.
You might want to consider BNM also - they avoid predation better than FHM otherwise look and behave very similarly. I'm not sure I could tell the difference, personally.
Hey, we all love FHM here, we just wish they weren't so damned slow!
