First of all, they're the same fish. We're farming native stocks, and we are required to do that. In other parts of the world, they're allowed to farm species that are not native to the area.
They are cultivated for farming, so they're several generations away from what was in the wild. It's a bit of a complex debate. You can argue that it's a good thing that they're not fit for survival, so they won't survive, but I think most people are aware that there are many, many more reasons for the decline of wild salmon than aquaculture. It's survival at sea.
NASCO, the North Atlantic Salmon Conservation Organization, in which I have participated for many years, is clear that survival at sea is the major cause of the decline of wild salmon worldwide, and there are many other instances in our area.
Terry, you may have something you want to add.
