In 1920 the production of salmon in Alaska was 65,080,539 as com- 
pared with 58,172,665 in 1919, an increase of approximately 12 per 
cent. The decrease in southeastern Alaska was 6,446,220, or a little 
more than 16 per cent. In central Alaska there was an increase of 
9,836,712, or approximately 101 per cent; in the western district the 
increase was 3,017,382, or approximately 40 per cent. The striking 
development of the season was the large catch of salmon in central 
Alaska, it being next to the largest ever recorded for that district, 
the catch of 1918 alone exceeding it. Considering Alaska as a whole, 
the 1920 catch shows that in comparison with that of 1919, cohos 
decreased 538,987, chums decreased 2,065,483, humpbacks increased 
6,217,635, kings decreased 192,525, and reds increased 3,487,194.
