SALMON TAGGING IN ALASKA., 1926 



103 



The general routes of migration, as indicated by the experiments of 1926, were 

 the same as outlined in the previous report. Fish entering Icy Strait are distributed 

 mainly to waters tributary to Icy Strait, Chatham Strait, Lynn Canal (1925), and

 entering Sumner Strait go mainly to Sumner Strait, Clarence Strait, Ernest Sound, 

 Behm Canal, and Revillagigedo Channel; and those entering at Dixons Entrance 

 are distributed to the west coast of Prince of Wales Island, the lower part of

 Alaska through the entrance that provides the most direct route to the streams 

 in which they will eventually spawn, and that they follow this most direct route with-

Certain differences are shown in the distribution of red salmon tagged early 

 in the season, as compared with salmon tagged later in the season at the same place. 

 No such difference is clearly marked in the case of the other species. In the case
