Blueback Salmon ; Sockeye Salmon 



Adult Female Little Redfish 



These small redfish are known from the Redfish Lakes of 

 Idaho, Big Payette Lake in Idaho, Wallowa Lake in Oregon, 

 Washington, Sammamish, and Ozette lakes in Washington, and 

 many small lakes in British Columbia and Alaska. 



Next to the chinook salmon, the blueback is the most im- 

 portant fish on our west coast, while in Alaska it is more val- 

 uable than all other species combined. In the Fraser River it is 

 exceedingly abundant, and is extensively canned along the lower 

 course of that river, and about the northern end of Puget Sound. 

 The annual catch of salmon in Puget Sound amounts to more 

 than $4,000,000, and consists chiefly of bluebacks and chinooks. 



The blueback salmon reaches a length of 2 feet and a weight 

 of 3 to 7 pounds. It is one of the most beautiful and graceful 

 of the Salmonidcv, and as a food-fish is scarcely inferior to the 

 Chinook salmon. Its flesh is of attractive colour, rich in oil, 

 and of superior quality when canned. 



We have carefully observed the spawning habits of both 

 forms of the redfish and the chinook salmon in the headwaters 

 of Salmon River, Idaho, during 2 entire seasons, from the time 

 the fish arrived in July until the end of September, by which 

 time all these fish had disappeared. A number of important 

 questions were settled by these investigations. In the first place, 

 it was found that all of these fish arrived upon the spawning- 

 beds in perfect physical condition so far as external appearance 

 indicated, no sores, bruises or other mutilations showing on any' 

 of more than 4,000 fish examined. During the spawning, how-
