Israel biologists say they've developed the world's first environmentally friendly aquaculture system. It uses enclosed tanks to raise fish anywhere in the world. The developing company - Grow Fish Anywhere - is currently settling a legal dispute with another group over adaptations to the patented technology.

Israeli marine biologists have found a way to grow fish anywhere in the world, regardless of climate or distance from water supplies.

Grow Fish Anywhere, or GFA, is a privately-owned Israeli company that has developed a network of enclosed tanks. The tanks connect to biological filters, where wastewater is filtered and run through the tanks again.

The first such commercial facility is in Hudson, New York, in the United States.

The GFA system uses tap water treated with salt from the Red Sea.

The water that's used to grow fish is constantly recycled and recirculated, so that there is zero discharge.

Fish that's grown in these tanks have a higher rate of growth and output.

[Professor Jaap van Rijin, Hebrew University]:
"If we maintain a biomass of let's say eighty kilograms of fish for cubic meter, then our yearly production per cubic meter is something like 120 to 130 kilograms of fish, so those systems are very, very intense. We can grow a lot of fish in a very compact way."

So, other than one percent of water loss due to evaporation, the rest is not wasted.

Solid waste from the fish is consumed in the algae tanks.

[Yossi Tal, Research & Development, GFA]:
"Right now the oceans are depleting from fish, what is left over there is being polluted and there is a big problem to deliver to the markets the needed seafood that... right now the demand is just rising. We believe that our technology will do that, we'll fill up this gap between demand and production."
