basis of market demand, and the general practice has been to classify the vari-colored 
fish with the whites, since the reds bring a higher price. The following determina- 
tions are necessarily confined to the two main classes, but the presence of intergrading 
colors must not be overlooked. Data were available for some early years, and for 
most of the years between 1923 and 1934, for 3 traps in Haro Strait, 3 in Birch Bay, 
1 on Lopez Island, and 2 in Admiralty Inlet. The average proportionate occurrence 
of red and white king salmon throughout the season was calculated for these four 
areas. These data are presented in table 44.

Occurrence of red kings does not differ materially in the various areas, although 
there is a greater early run in the northern districts and a heavier run in the Admiralty 
Inlet aiea. White kings differ considerably, however, with heavy fall concentrations 
in the northern areas. More than 75 percent of the season’s catch in Haro Strait 
is made during the month of September, as is approximately 60 percent of the catch 
in Birch Bay. Occurrence of white kings in the southern portion of Rosario Strait 
(South Lopez) is more even throughout the season, the peak of the run appearing dur- 
ing the month of August, while in Admiralty Inlet no definite peak of occurrence is 
shown. 
The average proportion of white kings in the total catch of red and white kings 
combined was then calculated for each week in the season and for the total season 
from the trap catches of the various areas. These data are presented in table 45.
