Yes, there are problems about the definitions of organic and sustainable, both of which have become marketing and competitive terms with little basic meaning. This discussion mentioned closed systems like that is the goal, however sustainability includes carbon footprint considerations, which is much higher for closed aquaculture systems, with their high energy consumption than for offshore aquaculture and there is no way around the problem -- pure physics.
