We managed to produce 150-200 lbs of fish in the same time it took to
grow sweet potatoes. There was a fish farming program at Walter Biddle
Saul Agricultural High School here during those years too. You might
want to see if they are still doing it.
Our project was run by Food & Energy Systems, Inc, an off-shoot of the
Penn State Urban Gardening Program. FES has since gone out of business.
