SALMON TAGGING IN ALASKA, 1926 



95 



A few of these fish went westward and were taken in Cross Sound and Slocum 

 Arm. The main route of migration, however, was to the eastward through Icy 

 Strait and thence, apparently, around the northern end of Admiralty Island to 

 Stephens Passage and Taku Inlet. Only a small component goes south through 

 Chatham Strait to Frederick Sound. The experiments at Douglas Island (to be 

 described later) corroborate the results of these in Icy Strait and show that an 

 important migration of reds passes Douglas Island on the way to Taku Inlet. These

results are strikingly different from those of the previous experiments. The tagging 

 of 1924 and 1925 was done early in the summer, mainly between June 23 and July 1, 

 and, therefore, tested the migration of the early part of the run only. A larger 

 proportion of these early fish went south in Chatham Strait to Frederick Sound; 

 none were taken in Stephens Passage, but there was a well-marked migration into 

 Lynn Canal, where the Chilkat and Chilkoot Rivers are. These are known to be 

 the sources of important runs of red salmon, and from these experiments it is evident 

 that the reds bound for these two rivers enter Icy Strait early in the season.
