miles from Ikatan Bay. The rate of travel to Nelson’s Lagoon was about 10 miles 
per day and to Bear River about 13 miles per day. 
So few fish tagged at Ikatan were taken at points to the eastward along the 
southern shore of the peninsula that the data can not be considered at all con- 
clusive. The indications are, however, that from 8 to 10 days are required for the 
journey from Ikatan Bay to Thin Point or Cold Bay, either of which is about 30 
miles distant. 
FROM MORZHOVOI BAY 
The most abundant returns from the experiments begun in Morzhovoi Bay 
were from Ikatan Bay, where many of the fish tagged in Morzhovoi Bay are evi- 
dently bound on their way to Bristol Bay through False Pass. Ikatan Bay is only 
some 20 miles distant, and the average time required to make the trip is close to 3 
days. 
A few tags attached in Morzhovoi Bay were taken at Nelson’s Lagoon and 
Bear River. Those fish tagged from the traps on the western and northern shores 
of the bay required an average of 17 or 18 days to make the trip, but those tagged 
in trap No. 5, on the eastern shore, required only about 11 days. This last figure 
is approximately the same as for the fish tagged in Ikatan Bay. Although the 
general impression gained from these figures is that the fish tagged in Morzhovoi 
Bay require a somewhat longer time to go to Nelson’s Lagoon and Bear River 
than did those tagged in Ikatan Bay, the data are too few to warrant definite 
conclusions. 
It was pointed out above that there is a distinct migration from Morzhovoi 
Bay to local spawning grounds to the eastward along the southern shore of the 
peninsula and especially to Thin Point and Cold Bay. The fish tagged in trap No. 5 
particularly entered into this migration. The distance to Thin Point is only about 
20 miles, but the time required was 6 days from the traps on the west side of the 
bay and 5.1 days from trap No. 5. This indicates a rate of travel of only about 
4 miles per day. To Cold Bay required, from the traps on the west side of the bay, 
an average of approximately 10 days and from trap No. 5 nearly 7 days. The 
distance to the point in Cold Bay where most of the fishing is conducted is approxi- 
mately 40 miles. The rate of travel was therefore about the same as to Thin Point. 
This illustrates again the fact noted above, that the rate of travel to near-by spawn- 
ing grounds is distinctly slower than to those more distant. 
The extent to which the fish linger about the place where they have been lib- 
erated is indicated by the average length of time elapsing between the time of 
liberation and the time of recapture in the same locality. In the case of the fish 
tagged at Unga Island in the Kelly Rock and Big Valley traps this was 5.1 days. 
Fish tagged in the Coal Harbor trap lingered about the Shumagin Islands for an 
average of 6.7 days. Those tagged in the traps on the western and northern shores 
of Morzhovoi Bay remained in that bay for an average of 6.2 days, and those from 
the trap on the eastern shore for 4.6 days. The average time between liberation 
and recapture in Ikatan Bay was about 2 days. It appears probable that the shorter 
delay in Ikatan Bay is associated with the nearness of False Pass, through which the 
fish pass in large numbers to the spawning grounds of Bering Sea.
