SALMON INDUSTRY. 



The most prominent features of the salmon industry f?rowinj]j out 

 of the operations of 1920 are (1) the continued falling off in the 

 catch of salmon in southeast Alaska and (2) the increase in pro- 

 duction in both central and western Alaska. But the catch of 

 salmon in any district may not be a sufficient indicator of the condi- 

 tion of the fisheries therein unless considered in connection with the 

 character of fishing activities, the amount of ojear used, lenj^th of 

 season, and the intensiveness of operations. Nor can an accurate 

 analysis of the condition of the fisheries be made until the position 

 and influence of these factors are determined; and even then there 

 are other factors of less prominence which may have an im]}ortant 

 bearinff on the question, as, for instance, the application of restric- 

 tive measures desi<?ned to afford more protection to the runs of 

 salmon. 



Consideration of certain pack fif^ures in the southeastern district 

 for a number of years back may be of interest. From 1912 to and 

 including 1920 the pack of canned salmon in southeast Alaska did 

 not vary markedly, except from 1916 to 1917 and from 1919 to 1920. 

 The first of these movements was upward, with an increase of more 

 than 1,000.000 cases in 1917; the second marked change occured in 

 1920. when there was a decrease of almost 900,000 cases from the 

 previous year. In the three seasons of 1917, 1918, and 1919 the 

 production of salmon in southeast Alaska reached its peak. In 1920 

 the production may be considered as normal, upon the basis of the 

 general average pack for a series of years, and was not exceeded in 

 the period from 1910 to 1916, inclusive, except in 1915. 



In central Alaska there was an increase in the pack of all sjjecies 

 of salmon except chums, and the total catch of salmon in that dis-
