Shrimp Farming in Ohio? Why Not West Virginia?

Microculture presents interesting possibilities for growing crops or raising animals on small areas of land. I have heard of small scale shrimp farming in Vietnam, but I figured that was due to lower costs and a tropical climate, but here's somebody who's raising shrimp in . . . Youngstown, Ohio, on some abandoned lot. I don't see how it could be cost-effective without scaling up the project, but it's an interesting endeavor. It makes you wonder how much of this type of small scale farming might be suited to a place like West Virginia.
