MIGRATIONS OF PINK SALMON 
659 
The percentage of recoveries in area 3 from the weekly taggings was much smaller 
than those in areas 1 and 2. No doubt many of the tagged salmon bound for this area 
were intercepted in the latter regions. Nevertheless, there were sufficient recoveries 
in area 3 to give some indication of the time when these salmon migrated through 
Clarence Strait. Although the seasonal trends in area 3 are not very marked, there 
is indication that more of the recoveries were made in the early part of the season 
than in the latter part. In other words, more pink salmon bound for area 3, and the 
areas above it, migrate through Clarence Strait in the early part of the season than 
in the latter part. 
The percentage of recoveries in areas 4 and 5 were so small that no definite trends 
occur in them. Many of the salmon bound for these areas were, no doubt, intercepted 
in areas 1,2, and 3. 
The percentage of recoveries in area 6 for the 1935 series of experiments was too 
small to indicate a definite seasonal trend. However, the percentage recovered from 
the 1936 series of experiments, although only slightly greater, indicates a possible 
upward trend in the latter part of the season. Since, in 1935, there was a misunder- 
standing on the part of the cannerymen in this area as to the method of reporting 
recoveries of tagged salmon, there is reason to believe the 1935 data are incomplete. 
This tendency toward an increase in the percentage of recoveries as the season pro- 
gresses is in accord with the results from the experiments carried on near Cape Chacon 
during the second and third weeks of August in 1925 and 1926. In fact the whole 
distribution of the salmon tagged during the second and third weeks of August in the 
1935 and 1936 experiments is in accord with the distribution of the salmon tagged in 
the 1925 and 1926 experiments. 
In discussing the distribution of the recoveries from the early tagging experiments 
in Clarence Strait, evidence was pointed out winch indicated that many of the pink 
salmon migrating along the west shores of Gravina and Annette Islands during the 
latter part of the season were bound for localities along the east shore of Prince of 
Wales Island in area 2. Further evidence in regard to this peculiar migration of the 
pink salmon in Clarence Strait may be found in the distribution of the recoveries from 
the 1935 and 1936 experiments. 
In discussing the localities in area 1 in which the tagged salmon were recovered 
(see tables 4 and 5), it was pointed out that the majority were recovered from the 
west shores of Gravina and Annette Islands. The total numbers, by weekly taggings, 
recovered in area 1 in the localities east of Cape Fox, Revillagigedo Channel, and 
Behm Canal, as a group, and the recoveries from the west shores of Gravina and 
Annette and Duke Islands, as a group, are given in table 6.
