TAGGING ADULT RED SALMON, 1922. 
41 
Fisheries, from two traps located off the southeastern shore of the island, in the 
vicinity of Kelly Rock. Of the 861 red salmon tagged only 1 was recaptured in 
either of these traps, being removed from the trap on the third day after tagging. 
From this it is clear that salmon released from the Kelly Rock traps do not linger 
in the vicinity, where they would be subject to recapture, but pass on immediately 
to other grounds. This is strikingly different, as we shall see, from the procedure 
of the salmon in Ikatan and Morzhovoi Bays, where many of them circled about 
the bays for a period of two weeks, during which time they were constantly in the 
danger zone. 
None of the fish tagged and released at Unga Island was taken at Red Cove, 
Acheredin Bay, or other local fishing grounds among the Shumagin Islands. Five 
of them moved eastward along the south shore of the Peninsula, one being captured 
at the mouth of the Ozernoi River, the other four being taken on the eastern shore 
of Cook Inlet. It is worthy of note that the four salmon bound for Cook Inlet 
passed on their way such important red salmon streams as the Chignik and Karluk 
Rivers. Although very extensive fisheries were being prosecuted at both these 
points no tagged salmon were observed there. 
The great majority of the captures from the Unga experiments were of salmon 
that had started westward on their migration instead of eastward. Furthermore, 
they proceeded directly to Morzhovoi and Ikatan Bays, without entering on their 
way the minor red salmon streams of Pavlof or Volcano Bays, Cold Bay, or Thin 
Point. Of the 601 red salmon tagged and released from Kelly Rock trap No. 6 on 
June 30, 6 were recovered in Morzhovoi Bay traps on July 6, 4 on July 7, and 5 on 
July 8, and on the last-mentioned date 1 specimen wrs recaptured in Ikatan Bay. 
Inspection of Table 9, in which are detailed the results of this marking, indicates 
that a stream of migrants from Unga Island was entering Morzhovoi and Ikatan 
Bays and that they first reached Morzhovoi Bay in numbers and a few days later 
were present in Ikatan Bay in full force. The last of those released from the New 
Kelly Rock trap on June 30 were taken in Morzhovoi Bay on July 20, three weeks 
later. How much of this interval was spent in Ikatan and Morzhovoi Bays can not 
be specified, but from information derived from tagging experiments conducted in 
these two bays it is evident that red salmon entering them may mill around in them 
and pass back and forth from one to the other for two or three weeks before pro- 
ceeding on their journey. Twenty-four individuals recaptured in Morzhovoi Bay 
had spent on the average 10 days between tagging and recapture. Fifteen indi- 
viduals recaptured at Ikatan averaged 13 days en route. The remaining recaptures 
of the June 30 experiment were made in Bristol Bay from July 14 to August 1 on 
the Naknek, Kvichak, and Nushagak fishing grounds. The salmon recaptured on 
July 14 was obtained by the Alaska Packers Association off Koggiung, in the estuary 
of the Kvichak River, distant by the shortest direct course approximately 465 miles 
from the point where tagged. If we assume that this fish began its migration imme- 
diately on being released after tagging, that it proceeded in a direct line to Isanotski 
Strait (False Pass), which it traversed without delay, that it pursued an undeviating 
course to the mouth of the Kvichak River and was there captured on the date of 
its arrival, it would have traveled at the average rate of 33 miles per day. All of
