Yes. With respect to the B.C. coast—not the Atlantic coast, which is a different situation because Atlantic salmon exist on the Atlantic coast—the report indicates that any direct spatial impacts are likely to be localized and restricted to the areas of open-sea net pens, primarily as a consequence of the effluents that are released from the net pens into the water directly affecting the water bottom in that area. But broader-ranging influences might be realized by the exchange of pathogens and disease.
