I thought one of the papers linked above said that the Sutherland spawning stock was dissimilar to Baker Lake and the others...but I think the more important point would be that even if they do have bits of the other fish in them, the fact that the Elwah and Sutherland fish are the same means that the Sutherland fish have made it out to sea and come back as adults, even if those adults can't make it back to Sutherland.

Fish on...
