When this issue came up many years ago, they did an assessment of the existing sites and they moved some sites around to try to address the issue. I think what you're talking about is a somewhat different issue, and that is siting the farms on migration routes.
It would be difficult in B.C. to move farms away from migration routes. The question is how much impact they have on fish when they migrate by. I think we have some information, but we certainly don't have enough. And if you moved them away, where are you going to move them to?
I just don't know if moving the sites around because they're on migration routes is really going to address the issue, because there are quite a few salmon on the west coast swimming around, and conceivably most places would be on a migration route.
