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. 
Tn this third edition of the report? considerable new material has 
been added, while some chapters have been entirely remodeled and 
materially enlarged. The statistical data have been brought up to 
January 1, 1920. The author is indebted to the Pacific Fisherman, 
of Seattle, Wash., for certain illustrations and to George C. Teal for 
permission to use his copyrighted picture shown as figure 11. Most 
of the illustrations are from pictures taken by the author. 
THE SPECIES OF SALMON AND THE RUNS. 
The Pacific coast salmons are all included in the genus Oncorhyn- 
chus. With them the fishermen incorrectly class the steelhead trout, 
which really belongs to the closely related genus Salmo. 
As long ago as 1731 the species of Oncorhynchus were first made 
known by Steller, who, almost simultaneously with Krascheninikov, 
another early investigator, distinguished them with perfect accuracy 
under their Russian vernacular names. In 1792 Walbaum adopted 
these vernacular names in a scientific nomenclature for these fishes.
