BULLETIN OF THE BUREAU OF FISHERIES 
The returns obtained in Prince William Sound correspond very closely to those 
obtained from experiments in Southeastern Alaska. 
Because the salmon runs in Cook Inlet and Prince William Sound are quite dis- 
tinct, the experiments in those districts have been considered separately. In Prince 
William Sound 2,172 of the 2,250 fish tagged were pink salmon, the most important 
species in that district. The results may be summarized briefly as follows: 
1. The pink salmon entering Prince William Sound through Montague Strait 
are distributed to virtually all parts of the sound. Two routes of migration are indi- 
cated; one is northeast along Montague Island to Hinchinbrook Entrance and from 
there to the bays and inlets along the east shore; and the other is northwest through 
Knight Island Passage to the streams on the west shore. 
2. The pink salmon taken at Montague Point, like those in Montague Strait, 
are widely scattered to all parts of Prince William Sound. These fish may have entered 
the sound through Montague Strait, in which case some of the fish complete their 
migration to the spawning grounds on the east shore while others turn back over the 
route already covered along Montague Island and some continue to the spawning 
grounds on the west shore. Some of the fish taken here may also have entered Prince 
William Sound through Hinchinbrook Entrance in which case the liberated fish were 
a mixed lot. This seems more probable and would account for the scattering of the 
fish from Montague Point, whereas if only fish entering through Montague Strait 
had been liberated at Montague Point, the northeasterly migration alone would have 
been expected. 
3. The distribution of fish tagged at Port Etches in Hinchinbrook Entrance was 
almost exclusively to the bays along the east shore of Prince William Sound. 
4. Fish caught at Squire Island in Knight Island Passage are derived in large 
part from those entering Prince William Sound through Montague Strait and are 
bound mainly for the streams along the western and northern shores of those waters. 
5. The fish passing Johnstone Point are bound chiefly for the streams on the east 
shore of Prince William Sound. 
6. In most of the experiments there were no differences in the distribution of 
pink salmon tagged early in the season as compared with those tagged later in the 
season at the same place. Usually the fish tagged in the earlier experiments were 
recaptured after a longer period of freedom than those tagged later in the season- 
indicating a slower rate of travel. 
In Cook Inlet, 1,893 salmon of all species were released during the 1929 tagging 
operations. Of this number 2 were kings, neither of which were recaptured; 788 were 
reds; 831 were pinks; 224 were chums; and 48 were cohos. The conclusions, based on 
data obtained from the four experiments conducted there, are as follows: 
1 . The distribution of the fish tagged at Flat Island varied with the species but 
was principally north in Cook Inlet. The red salmon tagged here on June 14 were 
taken in considerable numbers in the vicinity of English Bay, and a large percentage 
of all recaptures was made along the east shore of Cook Inlet south of Anchor Point, 
indicating that the red salmon passing Flat Island are largely bound for the smaller 
spawning streams in the lower inlet. Three reds were taken near Kodiak Island, and 
two were taken in Prince William Sound. The pinks, chums, and cohos were distrib- 
uted along the east shore of Cook Inlet south of Anchor Point. Three pinks were 
taken in Prince William Sound.
