Our licence right now at Middle Bay is for 1,200 tonnes a year; a typical salmon farm would be 2,500 tonnes or 3,000 tonnes a year.
The site has some limitations. We could put possibly as many as four more tanks on that one site, so I guess we'll be getting up into the commercial scale at that point—we're pretty much ready to jump into that. Because we're still fairly new at this, we are innovating on a daily basis, as it were. We're looking at all kinds of ways to improve the way we operate the system, but generally I think we are very close to commercialization. We've certainly had a lot of interest from the industry around the world, and we're in negotiations right now with a number of people to install trial systems as well.
