There are sites out there that do run a closed system profitably, but it really depends. It's very situation-specific. I think that if you tried to compete head to head with the salmon coming out of net pens, you would not be profitable. There are other situations where it may be profitable, and it may be profitable for a company to have salmon come out of a closed containment system to access a market niche.
I do think we should move forward with closed containment, because we want to keep up with the technology, but we also want to ensure that the industry is flexible. There are also other species, like sturgeon, for example. You can develop sturgeon in closed containment, and the value of the products is so great that it would be profitable. You can do it in such a way that would allow you to address conservation efforts and develop a good sector.
I think there's room for both types of systems. The bottom line is when you're developing closed containment aquaculture systems.... As I said earlier, salmon farmers use recirculating aquaculture systems for growing smolts, so they are constantly investing in the technology, and a lot that we know comes from that. The question is whether you can do it cost-effectively to grow market-size salmon, because the situation changes quite a bit when you move from a couple of hundred tonnes to several thousand tonnes. Right now in B.C. the cost of production is already very high, so if you were to move to closed containment you would exacerbate that problem.
