I understand there are negative environmental impacts associated with the aquaculture industry. In closed containment, I expect one of those is the fecal waste that is generated. Can you describe the different technologies that exist for dealing with waste from closed containment systems? Do we need to do more work in this area to improve the technology? Is that the only environmental concern with closed containment systems, or are there others?
