SOUTHEASTERN ALASKA SALMON STATISTICS 
639 
The chum fishery produces annually a few hundred thousand salmon. Since 
1913 the trend has been almost level except as it dropped in 1921 and 1927 on account 
of conditions which have been repeatedly mentioned. 
Cohos have been reported from Behm Canal since 1895. The catch is marked 
by wide fluctuations, the high peaks occurring in 1911, 1918, and 1923, and the low 
points in 1905, 1913, 1920, and 1927. The real condition of this fishery, however, is 
not shown in the data presented, as no doubt exists that many cohos were taken in 
Behm Canal by trollers who made no allocations of their catches. 
As measured by these incomplete data, the fisheries of Behm Canal show no 
material decline in production during a long period. Certain localities undoubtedly 
have been depleted to some degree, but the development of fisheries in new places has 
counterbalanced these losses and maintained the yield at a fairly constant level.
