I can touch briefly on the risk assessment; I know you're conscious of time.
Essentially what we're trying to do is go through each of the pathogens, making our best effort to figure out how disease moves, as I said earlier, between wild and farmed. Within wild, we know there's an awful lot of endemic disease and a lot of endemic pathogens in British Columbia that have been there for we don't know how long, but for a very long time.
Essentially, the understanding of disease transfer mechanisms is an area we're continuing to expand on. As Rebecca has mentioned, we have an active risk assessment program under way now to look at these issues. So far we have not detected anything that suggests we have a causal link between any wild salmon population health issue and aquaculture.
