I think it's important to realize why we grow fish in the first place. Fish are very excellent converters of feed into protein. We have other options--poultry, swine, beef--but those tend to take, depending on the animal, five to ten times as much feed “in” to produce a pound of fish “out”. That's why salmon, and fish in general, are a very efficient form of agriculture when you're growing protein. Right off the bat, fish are highly efficient in converting feed into flesh.
You're asking about the pressure on the wild fish that are used to make this fish meal that goes into growing the fish and the feed. As I mentioned earlier, we're aware of that. We're alive to the fact that we can't waste that. We have to be more efficient with that. Around the world we're reducing our reliance on those fish products and moving towards a lower and lower level of utilization of fish.
As I mentioned, in British Columbia our goal is to actually grow more salmon than the amount of fish we put into those salmon, and we'll be there in a couple of years.
