I'd just like to make it really clear that in my opinion--and there are many examples of this--closed containment is economically viable today. We have coho farms that are producing coho and selling into a niche market. We've got tilapia farms that have been growing fish in closed containment systems and selling to live markets in Vancouver, Toronto, Montreal, and New York City for 15 to 20 years already. These are closed containment systems. They work.
The thing that sets them apart is that they're producing a premium-priced product, so you can afford the technology that Clare just explained. When you go to a commodity product like Atlantic salmon and you're competing with producers around the world who are using a lower-cost technology to produce it, that is, net pens, then you're going to have a hard time competing unless you become extremely large scale with very high capital costs.
