Here is an article from fis.com about another type of high tech fish farm with some nice futuristic design.
Hawaii Oceanic Technology Inc. has created the Oceansphere. “These elegant, self-sustaining and untethered semi-submerged floating pods are a revolution in open ocean aquaculture technology”, according to the fis.com article. The system is operated without the use of fossil fuels, which makes it environmentally quite acceptable.
As mentioned in the article, the company’s “plan is to demonstrate the feasibility of this technology and, as Jacques Cousteau said, farm the ocean as we farm the land.”
