Fisheries committee  On the question of scale, it's hard to say. I take your point that if things go wrong and you're small, the consequences are not as dramatic, but there can be real advantages of scale, of being bigger. There are economies of scale once you know what you are doing. To your more g

Fisheries committee  Sure. I derailed myself a little bit as I was going through my opening remarks. Based on the data from the systems that were in operation or are currently in operation and that we were able to model, that is indeed the case, but it's underpinned by the level of technology that

Fisheries committee  I think it's inverted. The amount of animal-derived protein in a farmed salmon diet, although it doesn't have to be this high, tends to be much higher than the amount of animal-derived protein that ends up going into a typical swine or dairy system.

Fisheries committee  In Canada, I can think of the Arctic char farm just outside of Truro. It's on the Millbrook reserve. As far as I know, it's in operation It was opened probably four or five years ago.

Fisheries committee  I'm not a fisheries biologist, but my understanding is--

Fisheries committee  I understand that. Our friends from the west coast are aware of some in southern B.C. I think there's a flow-through system there. I don't think it's a recirculating system. As for char and salmon, the one reason people are growing char in recirculating systems is that you get

Fisheries committee  You're absolutely right. One of the really interesting outputs of our work was that we realized how important location is. Location matters, if you're concerned about large-scale potential contributions. Location matters in terms of local ecological effects, but it also matters i

Fisheries committee  I'm sorry, of course. I just didn't hear the beeping.

Fisheries committee  I apologize. I didn't realize that I had rambled.

Fisheries committee  Coarsely speaking, if you're just looking at the feed required to grow a certain biomass of fish, in salmon aquaculture net-pen systems it's around 1.3 kilograms. Sometimes they do better. Sometimes, when things go badly, it's higher. My recollection on beef productions is like

Fisheries committee  Thank you for your interest and for the invitation to appear here. This is the first time I've ever had this sort of opportunity. My name is Peter Tyedmers. I'm an ecological economist. My training includes undergraduate degrees in geological sciences and the law prior to undert
