Fisheries committee  To add to that as well, we commented on Dr. Wright's study and he commented on ours. He actually sat on our technical advisory committee. There was some back and forth on the assumptions used, and we agreed to disagree on the assumptions.

Fisheries committee  No. For the net pens, you'd be looking at probably 15 kilos per cubic metre.

Fisheries committee  Yes, if you're looking at number of fish—

Fisheries committee  Slide 13 is actually a land-based flow-through system. By their very nature, based on the fact they are flow-through systems, they do need to be next to a high-quality water source. Likewise with slide 14 on the recirculating aquaculture systems, they also require a high-quality

Fisheries committee  The recirculating aquaculture systems that we looked at were specifically for saltwater Atlantic salmon. We didn't look at any type of artificial salination of the water, such as Instant Ocean. If you were to look at something like that, I think the costs would be prohibitive.

Fisheries committee  The two red Xs that appear on slide 12, in particular, just mean that those two factors weren't analyzed in that case, because with flow-through and no aeration, the amount of water required for the stocking densities for the flow-through was unfeasible. I can't remember the numb

Fisheries committee  Actually, I think they're using the same type of technology in China. It's just that the regulatory hurdles in China are less than they are here.

Fisheries committee  I've run out of time, and I can't find the specific numbers, but they are considerably higher for the closed containment. I would hazard a guess of 10 to 15 times higher.

Fisheries committee  They're considerably higher.

Fisheries committee  I would just add that in addition to any types of mechanical problems that may be encountered, there's the human element as well. In virtually every kind of closed containment system that I've seen, they've always had some type of loss because the operator has failed to do someth

Fisheries committee  Erosion.

Fisheries committee  I think that Canadian companies actually play quite well on the global market. It's a question of brands more than anything. There's a company on the west coast, PR Aqua, that has exported its technology to the U.S. and Chile for hatchery production and for recirculating aquacult

Fisheries committee  The densities for an open net-pen system are about 15 kilos per cubic metre. For land-based and recirculating aquaculture systems, you're looking at a minimum of about 50 kilos per cubic metre. The primary reason for that is to take advantage of the capital costs, because the dif

Fisheries committee  Essentially they're different brands, AquaOptima and the system we used in our financial feasibility study. We had to start somewhere, so we chose the system based on the recommendations of a design consultant we had. There are various types and brands. AquaOptima is one, and the

Fisheries committee  It is emerging. There are probably four or five companies around the world that are developing recirculating technology. A number of them are based in Europe.
