Blueback Salmon; Sockeye Salmon 



waters, and the spawning beds are always either in the inlets 

 to the lakes or in the lakes themselves; so far as known there 

 is no exception. 



Adult Male Blueback Salmon 



In the Columbia River this salmon is called the blueback; 

 in the Fraser it is the sockeye, sawkeye, or sau-qui; in Alaska it 

 is the red salmon or redfish, while among the Russians it is 

 the krasnaya ryba. 



In certain small lakes in central Idaho, northeastern Oregon, 

 Washington and British Columbia are found 2 forms of this 

 salmon, one weighing 3 to 7 pounds, and known as the redfish, 

 the other 10 to 12 inches long, and weighing one-half pound. 

 The latter is known as the little redfish, Kennedy's salmon, or 

 walla. 



It has been definitely proved that the large redfish come up 

 from the sea and are identical with the blueback salmon. The 

 little redfish does not appear to differ structurally from the large 

 redfish, and has been thought to be the young of that species; 

 if it is not, then the young blueback is unknown. The migra- 

 tion from the sea of these small fish has not been observed, 

 and there is some strong evidence showing them to be resident 

 in the lakes in whose inlets they have their spawning beds.
