I agree. As the fish get closer to their natal streams, the effect of mixed stock fisheries become less. That's why ocean harvest can be both damaging and difficult to assess. Those salmon caught in the open ocean could be from anywhere. As the fish get closer to their natal streams (e.g., Buoy 10) , the effect of the mixed stock fishery becomes manageable, but it doesn't disappear completely (ask the folks in Idaho).

When (or if) the fish arrive at their spawning grounds, the effect disappears entirely.
