INTRODUCTION 



The most valuable commercial fisheries in the world, excepting 

 only the oyster and herring fisheries, are those supported by the salm- 

 ons. Of these the most important by far are the salmon fisheries 

 of the Pacific coast of North America, where California, Oregon, 

 Washington, and Alaska, including also British Columbia, possess 

 industries representing millions of dollars of investment and millions 

 of output annually. In Siberia the fishery is increasing in impor- 

 tance annually as means of transportation become better, while Japan 

 is also becoming a large factor in the salmon markets of the world 

 through her investments in the salmon fisheries of Siberia and, to a 

 lesser extent, through fisheries prosecuted in her own waters.
