in Felice Strait and Revillagigedo Channel. The time of travel is noticeably short, 
the minimum being 1 day and the maximum 12 days. 
CHUM SALMON 
Fifty-two chum salmon were tagged at Gravina Island during 1927. Only three 
were recaptured (5.7 per cent), one each from the following localities: Seal Cove, 
Gravina Island, 5 days; Vegas Islands, Felice Strait, 6 days; Clover Passage, Behm 
Canal, 1 day. 
COHO SALMON 
Eleven coho salmon were tagged at Gravina Island during 1927. Only one was 
recaptured, which was taken at Guard Islands, Clarence Strait, in eight days. 
CONCLUSIONS 
Although the experiments of 1927 involved the tagging of relatively few fish 
distributed among eight quite distinct localities, the results have corroborated the 
previous experiments to a remarkable degree. The percentages of recoveries are 
approximately the same as those obtained in 1924, 1925, and 1926, and are collected 
in Table 15.

The routes of migration are virtually identical with those shown in the earlier work, 
and in most instances the percentages of fish taking the various routes from a given 
tagging station are as nearly the same as might be expected. These were discussed 
in some detail in the report dealing with the experiments in 1926 (Rich and Suomela), 
and it does not, therefore, seem necessa^ to repeat that treatment here. The partic- 
ular value of the experiments described in this report lies in the fact that they support 
so strongly the previous studies of the migration of salmon in the intricate channels 
of southeastern Alaska. 
UGANIK BAY, 1927 
Red salmon are taken in fairly large numbers in the fishery in Uganik Bay on 
the northern shore of Kodiak Island, particularly in two traps on the western shore. 
During the season of 1927 126,000 red salmon were reported as captured in this bay, 
and in 1926 the catch was over 274,000. It was suspected that these might belong to 
the Karluk River run, and to test this 700 red salmon were tagged and released on 
August 19 and 20, 1927, from the Broken Point trap of the San Juan Fishing & Packing 
Co. Three hundred and seventeen tags were taken later in the commercial fishery and 
were returned with data as to when and where the fish were captured. In addition 
to those taken in the commercial fishery 86 were observed to reach the Karluk count- 
ing weir on their way to the spawning grounds. Some of these were captured, but
