THE PACIFIC SALMON 



THE salmon of the Pacific is a genus that 

 is very close to the Atlantic salmon, differ- 

 ing chiefly in the increased number of anal 

 rays and in the fact that they spawn but 

 once and all die after spawning. 



When in the sea the salmon are supposed 

 to dwell 20 to 40 miles off the mouth of their 

 native river and return to spawn, being 

 attracted by the cold river water. 



There are five species of salmon in the 

 Pacific. 



The largest species is the Quinnat, 

 chinook, tyee or king salmon (Oncor- 

 hynchus tschawytscha) which is found from 

 Monterey Bay to northern Alaska and also 

 in the Siberian rivers. This fish frequents 

 large rivers and is taken in the Yukon at 

 Dawson which is 1,500 miles from the sea.
