BULLETIN OF THE BUREAU OF FISHERIES 
PINK SALMON 
The returns from pinks tagged at Cape Decision, Sumner Strait, are presented 
in Table 13. These data would indicate two important migrations. The main migra- 
tion traversed the waters of Sumner Strait to its junction with Clarence Strait, 
thence southerly in Clarence Strait. Two individuals of this migration were recap- 
tured in Ernest Sound. One return is noted from Skeena River, British Columbia. 
The second and minor migration was northerly into Chatham Strait, whence 16 
returns are reported.

1 Location doubtful. 
These results differ materially from those secured from the experiments of 
1924 and 1925 at Ruins Point, although this locality is just across Sumner Strait 
from Cape Decision. In the experiments at Ruins Point a large number of pink 
salmon went to various localities along the west coast of Prince of Wales Island, 
and comparatively few went north into Chatham Strait. The conditions were just 
reversed in this experiment at Cape Decision. None of the pinks tagged there were 
taken along the west coast of Prince of Wales Island, and a large percentage went 
north in Chatham Strait. These differences may, of course, be due to chance, but 
it seems more likely that they are indicative of a distinct difference in the com- 
position of the schools from which the tagged fish were taken. It seems unlikely, 
however, that such marked differences would be found between the fish at two points 
so close together at any one time, and we are inclined to ascribe these differences 
to differences in the runs of 1924 and 1925 as compared with that of 1927. Since 
the fishery was virtually a failure on the west coast of Prince of Wales Island in 
1927, it is not particularly surprising that few fish bound for this region were found 
among the catches at Cape Decision. 
CHUM SALMON 
The chums tagged at Cape Decision and again captured followed a northerly route 
into Chatham Strait without exception. Three individuals were recaptured at 
Cape Decision 5 to 15 days from the date of tagging. One entered Frederick Sound 
and was recaptured at Security Bay; four were taken along the Chatham Strait 
shore of Ivuiu Island; and one was recaptured at Point Hepburn on Admiralty 
Island.
