The United States responded that no other country applied similar export restrictions on these species or any other species. Instead, they limited their authority to requiring a report of catch in their territorial waters and Exclusive Economic Zones. The selectivity reflected in Canada's export controls indicated the unique concentration of processing jobs in the freezing and canning operations associated with these species. The United States showed evidence that the non-restricted salmon accounted for almost half of Canada's total salmon exports over the past few years. Consequently, Canada's argument that the export restricted species were distinguished by their unique importance in international trade could not be accepted.
