To put things in perspective, you also need to read the scientific studies on the impacts of commercial fishing (the alternative to aquaculture) and view the relative ecological impacts per ton of fish produced.

Sorry that you don't read the scientific literature or comments by knowledgeable people who know a lot about the subject of offshore aquaculture and are strong supporters, without benefiting directly or even indirectly (except for better seafood availability). I do have experience with recycle aquaculture systems (RAS) and my consulting activity would benefit greatly from the activists push to closed recycle systems. However, having made a living in the RAS area, I fully understand the fundamental limitations of recycle aquaculture and the huge advantages of offshore aquaculture. Recycle aquaculture is excellent for maturation, spawning and producing fingerlings for offshore net pens, but you can't beat offshore for growout where the weather and water temperature is adequate (ie Hawaii). The high capital cost and energy consumption of recycle systems is inherent in the physics and biochemistry of the problem and no amount of hope, desire, activist beliefs, or taxpayers money will change the situation. Have you even seen the operation in other areas of the world or are you just depending upon other activists for you information about the problems? Most of the activists in the anti-aquaculture camp do have fund raising objectives, where it is easy to fight a non-significant opponent than one that can fight back like commercial fishermen, long liners, bottom trawlers, etc. Disinformation is par for the course for fund raising.
