Mr. Chair, I'll attempt to respond, and perhaps my colleague, Mr. Shoemaker, may be able to add something.
With respect to specialization or any information I can provide on Atlantic salmon, I can confirm that at no time in recorded history have Atlantic salmon been documented either in the north Pacific, to the extent where Yukon or Alsek River origin Pacific salmon stocks would occur, or, likewise, in the Yukon River watershed or adjacent marine areas.
To the best of any information on hand or available to us, at least in the context of the north Pacific and Bering Sea, we have not identified any occurrences of Atlantic salmon in these regions, Mr. Chair.
