Hawaii Oceanic Technology, Inc. has created the Oceansphere™. A revolution in open ocean aquaculture technology, the Oceansphere™ makes farming fish in the open ocean a practical reality. Self-sustaining and untethered to the ocean floor, the Oceansphere™ is designed to produce large harvests in a very small footprint. For example, twelve Oceanspheres in less than half of a square mile can yield as much as 24,000 tons of seafood.
