It's an interesting thought, isn't it? Putting fish farms into spent coal mines? I hooked you right in with that one!
It's what they are thinking in West Virginia, where coal mines are famous for providing the livelihood of miners and their families.
Farmed fish are now accounting for about half of the world's annual consumption (mostly due to farmed salmon) of 110 million metric tons of fish. The experts say, demand will soon exceed supply. We're going to need more fish farms.
With an estimated 1,000 closed mines in Pennsylvania and West Virginia, some are beginning to look at those empty pits as future “fishing holes.” Except the fish will be farmed and caught for consumers in grocery stores.
The Freshwater Institute in Shepherdstown, WV, estimates that turning mines into fish farms could generate hundreds of jobs and millions of pounds of fish annually. And here's the best part: the particulars of mine water are especially conducive to raising fish. Mine water temperatures hold steady at a brisk 56 degrees, which is impossible for human swimming but perfect for what else? Artic char, salmon and trout.
It's an idea whose time has come. When it was put forward in 1994, West Virginia dreamed of having hundreds of mines, but 16 years later, has only two. America's fish consumption was not so great then, but now, demand is up.
And to be sure, this may be not a case of “making lemonade from lemons,” but making dinner from leftovers found in a coal mine.
Greenification at its best.
