1 All dates are closed days. 
1 East of Whidbey Island and south of line Point Wilson to Point Partridge. 
* North of line Sand Point to Patos Island (Birch Bay, Boundary Bay and Point Roberts areas). 
The closed periods were introduced largely for the protection of the pink salmon 
and so at first were confined to the odd-numbered years, except in 1924, when it was 
hoped that there might be a fair run of pinks from the fry liberated by the hatcheries 
from eggs taken in Alaska. Since 1930 this closed period has been extended to the 
even-numbered jmars for the protection of the sockeye. The fall closing date was 
inaugurated in 1921 and applied to all districts. This closing protects a considerable 
portion of the chum salmon runs, and a small percentage of the cohoes. 
SEASONAL OCCURRENCE OF EACH SPECIES 
The seasons during which each species migrates through the salt water toward the 
spawning grounds is of the utmost importance from a standpoint of conservation as it 
determines, to a great extent, the possibilities of so regulating the fishery as to allow 
the talcing of the more abundant species, while protecting the less abundant. There 
is, of course, considerable variation from season to season in the time of run, although a 
general average may be obtained. The traps furnish the best measure of seasonal 
occurrence since a trap does not fluctuate from day to day in its fishing effort, but con- 
tinuously samples the runs that are passing by. 
For sockeyes data were used for 12 traps, all located north of Deception Pass. 
They fished in various years from 1896-1934, catching a total of 13,129,869 sockeyes. 
In making a seasonal curve (fig. 11), the total catch of each 7-day period was divided 
by the number of trap-fishing days. However, for sockeyes the trap-fishing days for 
each trap were weighted by the fishing efficiency of that trap. (Cf. page 768.) For 
species other than sockeye the traps were not weighted. 
For king salmon the catches of 17 traps were employed; 7 were north of Deception 
Pass, 4 at West Beach, 2 at Middle Point, 2 in the Hope Island Area, and 2 in Ad- 
miralty Inlet. They caught a total of 580,698 fish from 1900-1934. 
The pink-salmon curve was derived from 4,467,115 fish caught in 16 traps; 9 
located north of Deception Pass, 1 at Ebeys Landing and 6 in Admiralty Inlet. 
Since little effort was made to take pinks during the earlier years of the fishery, the 
material used is from odd-numbered years from 1919-33. As 1919 is the only year in
