I'EKCKNTAGE OF SALMON CaUGHT IN EaCH ALASKA DISTRICT, BY PRINCIPAL 



Forms of Apparatus. 



In 1920 the production of salmon in Alaska was 65,080,5-39 as com- 

 pared with 58,172,005 in 1919, an increase of approximately 12 per 

 cent. The decrease in southeastern Alaska was 0,440,220, or a little 

 more than 10 per cent. In central Alaska there was an increase of 

 9,886,712, or approximately 101 per cent; in the w^estern district the 

 increase was 3,517,382, 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 2,005,483, humpbacks increased 

 6,217,035, kings decreased 192,525, and reds increased 3,487,194.
