BULLETIN OF THE BUREAU OF FISHERIES 
PINK SALMON 
In the 10-year period from 1925-34, the pink salmon catch in the region was 
more than 50,000,000 fish, of which 60 percent were taken by purse seines, 27 percent 
by traps, 12 percent by Fraser River gill nets, and 2 percent by minor gear. Of the 
trap-caught fish, taken between 1895 and 1934, about 5 times as great a catch was 
made north of Deception Pass as south of that point. The peak of the seasonal runs 
in the southern part of Puget Sound is about 10 days earlier than in the northern 
part. Indices of abundance from purse seines and traps indicate that, following the 
obstruction at Hell’s Gate in 1913, which prevented them from reaching their spawn- 
ing grounds in the upper Fraser River, the pinks declined to about one-quarter of 
their former abundance. 
CHUM SALMON 
The runs of chum salmon occur during the last part of the fishing season, and 
have been taken chiefly by purse seines in the Puget Sound district, as most of the 
traps have ceased fishing by the time that the runs appear in any quantity. The 
chums of Admiralty Inlet were found to be approximately 38 percent 3-year-olds, 53 
percent 4-year-olds, and 9 percent 5-year-olds at maturity. The peak of the runs 
in the northern part of Puget Sound occurs about 2 weeks earlier than in the southern 
part. An index of abundance from Admiralty Inlet traps shows abundance in recent 
years to be less than half that of the period previous to the war. The average size 
of delivery by purse seines also indicates a higher level of abundance previous to 
1915.
