In 1907 there was some demand for pinks and the medium take per trap was over 
60,000. In 1909, a big sockeye year, only 50,000 per trap were utilized. In 1911, 
with a small sockeye run and an increasing demand for pinks, the median catch per 
trap was over 100,000. The median catch per trap was only 60,000 in 1913, again a 
big sockeye year, but on comparing it with 1911 and 1909 it is obvious that in the 
big years, either no pinks, or very few, were used from many of tlie traps. Eliminating 
those traps taking less than 20,000 pinks from the 1913 distribution, and they are not 
part of the distribution, as shown by 1911, the median catch is over 110,000. 
Since 1913 the demand for pink salmon has been good, and yet the highest median 
catch, in 1917, has only been over 30,000 per trap. If this evidence of a tremendous 
decline in abundance is not sufficiently convincing, one needs but note the size of the 
maximum trap catches. 
In the past 10 cycles, 1915-33, only 8 trap catches have exceeded 120,000 pink 
salmon, yet in the 8 earlier years this was exceeded 64 times. Considering only the 
earlier years when there was some demand, 1907-13, it was exceeded 62 times. In 
the same 4 cycles 29 catches were made of over 190,000 — larger than any single
