BULLETIN OF THE BUREAU OF FISHERIES 
Strait and were taken on the eastern shore. The fact of chief interest, however, is 
that from both north and south of the entrance to Kasaan Bay a large percentage 
of the recaptured fish were taken either in the bay or at its entrance, and it would 
appear from this that the runs to streams in Kasaan Bay provide an important 
element in the runs intercepted by traps both north and south of the entrance to 
the bay. 
It is equally certain that the traps in question catch pink salmon that are bound 
for other localities, but it seems impossible to make any more exact statements than 
these or to evaluate the extent to which Kasaan Bay fish enter into the catches of the 
traps just north and south of the entrance of the bay. In order to do this many 
more fish would have to be tagged, and it would be necessary to have much more 
detailed information than is available as to the relative fishing effort in the respective 
localities. 
One hundred and eighty-six chum salmon were tagged during the course of the 
Kasaan Bay experiments. Thirty-six were later recaptured, of which 24 came from 
the bay, 9 from scattered points in Clarence Strait both north and south of the en- 
trance to the bay, and 1 each from Behm Canal and Sitklan Island. Although the 
number of returns is small, they indicate clearly the importance of Kasaan Bay as a 
source of the chums taken in Clarence Strait near the entrance to the bay. 
Out of 61 red salmon tagged in this locality 15 were returned. Two of these 
were taken at Island Point and 1 at Skowl Point in Kasaan Bay. The others were 
taken at scattered places in Clarence Strait both north and south of the point of 
tagging and on both sides of the strait and 1 was reported from the Mezidan River in 
British Columbia. It is apparent that some of the reds caught in this region are 
native to the streams of Kasaan Bay, but the data are too few to warrant any con- 
clusions as to the extent to which this is true. 
One hundred and seventeen cohos were tagged here and 15 were recovered. Of 
these only 2 were taken in Kasaan Bay, 1 came from Wark Canal in British Columbia, 
1 from Behm Canal, 1 from Revillagigedo Channel and the others from various points 
in Clarence Strait. As in the case of the reds, no definite conclusions can be reached 
as to the importance of Kasaan Bay cohos in the catch of this species in the traps of 
Clarence Strait. 
CONCLUSIONS 
1. The fish taken in the traps in the region of Cape Fox are predominantly 
native to Alaskan waters and include comparatively small percentages of fish derived 
from the streams of British Columbia. 
2. The catch of the traps in Clarence Strait near the entrance to Kasaan Bay 
contains fish native to the streams of Kasaan Bay in rather large numbers, but also 
includes fish bound to other localities in what may be equal or even greater numbers. 
No reliable evaluation of the proportion of Kasaan Bay fish in these catches can be 
made with the data at hand.
