BULLETIN OF THE BUREAU OF FISHERIES 
METHOD AND LOCALITY OF CAPTURE 
Chum salmon are taken chiefly by purse seines in Puget Sound and the Gulf of 
Georgia and by gill nets in the Fraser River. Chums run so late in the fall that 
most of the traps close before they are abundant, and very few are taken on Swiftsure 
Bank, as the weather is not conducive to ocean fishing at that season The chum- 
salmon catches have depended as much upon economic conditions as upon abundance, 
usually being larger on the even-numbered years, due to the absence of pink salmon, 
which furnish the cheaper grades on the odd-numbered years. 
The actual number of chum salmon caught in Puget Sound is shown in table 55. 
These figures cannot be correlated with the canned pack as large quantities of chums 
were sometimes bought in British Columbia. The numbers taken in adjacent 
Canadian waters cannot be estimated from material on hand as chums were used for 
canning, freezing, smoking, dry-salting, and for export in a raw state. 
SEASONAL OCCURRENCE IN NORTHERN AND SOUTHERN DISTRICTS 
With the chums, as with the pinks, there is a considerable difference in time of 
run between the northern and southern districts of Puget Sound. However, the 
southern pink salmon run earlier than the northern, whereas for chums the situation 
is reversed.
