An Israeli innovation for raising seafood anywhere -- including the desert - could be the answer to the world's growing problem of over fishing and water shortages.

"Our technology is totally independent of the sea," says Dr. Yossi Tal of Israel's Grow Fish Anywhere (http://growfishanywhere.com), a company that invented a way to raise fish commercially under any kind of conditions.

"We are establishing our own unique ecology in our system to sustain the fish, without discharging any pollution."

GFA's solution could signal a breakthrough as the world's fishing industry faces the effects of over fishing, as well as chronic water shortages.

Producing one kilogram of fish conventionally requires 5,000 to 7,500 liters of water, according to GFA. founder Dr. Jaap Van Rijn, head of the department of animal sciences at the Hebrew University of Jerusalem (www.huji.ac.il). In the GFA. system, the amount required is just 40 liters of the precious fluid.
