the catches at the fishing grounds of Olga Bay. This shift in the fishing areas was 
accompanied by a shift in the type of gear used from seines to traps. The red salmon 
taken in Alitak and Moser Bays are undoubtedly Olga Bay fish, however, since the 
salmon entering Olga Bay must pass through Moser Bay, which is little more than a 
widening of the lower end of Olga Strait. It has been necessary for us to treat Moser 
and Alitak Bays as a single unit since in several years since 1914 the catches were 
reported as from “Alitak and Moser Bays,” and it has been impossible to segregate 
the catches made in these two bays. 
Alitak Bay is, however, the channel through which all salmon taken in Olga, Moser, 
Dead, and Portage Bays have approached their particular streams, so that a strict 
allocation of catch to the respective bays is not essential to a correct understanding 
of conditions in this district, at least in so far as the red salmon are concerned. Traps 
located on the east shore of Alitak Bay and traps set near the entrance of or between 
Dead Bay and Moser Bay take some red salmon. There are, however, no red salmon 
streams in Portage Bay or Dead Bay, and no red salmon were reported from either 
locality until 1925. There is no evidence that the red-salmon catch of this district 
draws upon other than the Olga Bay runs, nor is there evidence that this run is drawn 
upon by fisheries in other localities. 6 
Olga Bay has seven tributary streams which are used by salmon, but of these only 
four are recognized as red-salmon streams, and two of these are of little consequence. 
The important red-salmon streams are thus only two in number; one enters the bay 
from the north about midway between the east and west ends of the bay, and the 
other empties from the south near the west end of the bay. These streams are about 
30 feet in width, 2 feet in depth, and flow at the rate of about 1 % miles an hour. 
The south stream is by far the more important; it is the outlet of two small lakes and 
several ponds; and upon its production of red salmon, the fishery largely depends. 
A comparison of these two streams shows the south stream produces six times as 
many red salmon as the north stream. Of the less important streams, the one at the 
east end of the bay known as Horse Marine has provided the greater number of reds 
in late years, whereas 30 years ago the one in the northwest section of the district 
at Silver Salmon Bay was the more productive. 
Since 1924 the commercial catch of red salmon in the Alitak Bay district was 
restricted by the imposition of Federal regulations authorized under the act of Con- 
gress of June 6, 1924, providing that the escapement in streams where weirs are 
maintained for the purpose of counting salmon, shall equal the commercial catch. 
Weirs were first set across the north and south streams in 1923, and counts were made 
as shown in Table 8:

In addition to the foregoing, there was an estimated escapement of 25,000 reds 
into Horse Marine stream in 1926, while a similar estimate in 1927 gives that stream 
6 It has been noted in the past year or two, however, that many of the fish passing through the weirs in this district bear the 
marks of gill nets. Just where the Olga Bay fish pass through a gill-net fishery is not definitely known but it seems probable that 
it is along the northwest coast of Kodiak Island.
