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!
Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
