I have one quick question, Dr. Sheppard, if I may, and it's an important question.
In any of the research, has anyone modelled the possibility of a smolt or fry navigating from, say, the mouth of the Fraser River? If you take a look at all of the islands, all of the channels, and you say that the farms are spaced far apart, sometimes 3 kilometres, sometimes 50 kilometres, I think the relevant question is can a fry emerging from the Fraser River navigate to the wintering and the growing grounds? And has anybody modelled the chances of success of that fry going through any channel or any passage between the islands that doesn't contain a fish farm? What would the probability of that be?
