of the lakes of Oregon and Washington are founu the 

 young of the blue-back salmon which are commonly 

 called redfish. These fish never leave these lakes and 

 therefore never attain a size of more than five to seven 

 pounds. 



Head, short and pointed and light olive in color; un- 

 der jaw, white; body, long, slim and rather flattened; 

 back, blue; sides, silver; belly, dull white; dorsal fin, 

 dark; others flesh color; tail, rather narrow and well 

 forked; gills, 13 to 15. As the spawning season ap- 

 proaches the whole fish takes on a decided reddish cast, 

 which sometimes becomes as dark as a brick-red. The 

 jaw becomes very much hooked, and a few spots ap- 

 pear. 



THE SILVER SALMON 



(Oncorhynchus kisutch) 



In line of importance the silver salmon occupies the 

 next place. It is also known by a number of names, 

 among which are koho, skowitz and kisutch. It is a 

 small fish, rarely exceeding 16 inches in length and 

 never reaching more than ten pounds in weight. Its 

 range is from Alaska south to Monterey Bay, where it 

 has recently been planted and seems to flourish. It 

 spawns in the smaller coast streams, never going far 

 from the salt water. Its run begins about the first 

 of September, spawning in October and November. 



Head, short with blunt snout; opercles or gill covers, 

 very convex; body, shaped very much like the Chinook; 

 back, bluish green; sides, silver white. It has but few 

 spots and these are confined pretty much to the head, 

 upper fins and tail. Gills, 13 or 14. 



THE HUMP-BACK SALMON 

 (Oncorhynchus gorbuscha) 



This is another small species, rarely exceeding six 

 pounds in weight but more commonly from three to 

 four. Its range is from the Sacramento river, where it 

 appears in limited numbers, north to Alaska. 



Body, slim, scales very small; back, blue and sides 

 silvery white. Profusely spotted on the after part of 

 the back, with large oval spots on the tail. Gills, 11 

 to 13. 



THE DOG SALMON 

 (Oncorhynchus keta) 



The dog salmon rarely exceeds ten pounds in weight.
