DO SALMON FEED IN FRESH WATER? 39 



DO THE SALMON ENTER FRESH WATER FOR 

 THE SOLE PURPOSE OF SPAWNING? 



I believe that they have another reason. 

 Most fish love warm water and enjoy the 

 sunlight — in fact, love to bask in the sun. 



After a winter of heavy snowfall the 

 water is cold and the salmon are late in 

 arriving, but if the snowfall is light the fish 

 arrive early. 



The lower waters of the Grand Casca- 

 pedia, being fed by numerous mountain 

 brooks, are cold. I found the temperature 

 of the water rose as I went up stream and 

 also that the fish in the upper waters had 

 more life than those I had taken in the cold 

 water below. This lack of energy in fresh 

 run fish may be influenced by the cold water, 

 or the fish may not have become accustomed 

 to the somewhat sudden change from salt 

 to fresh water, for I have no doubt that they 

 are affected as a man from the lowland 

 would be who suddenly found himself in a 

 high altitude. 



A very interesting experiment was tried
