34 ALASKA FISHERIES AND FUR INDUSTRIES IN 1915. 
In 1915 the total number of purse and haul seines operated in the 
salmon industry of Alaska was 361 as against 336 the previous year. 
This gain of 25 seines for 1915 occurred almost wholly in southeast 
Alaska. 
Of the total catch of salmon in Alaska in 1915, the proportion taken 
in traps was 42 per cent, by seines 29 per cent, by gill nets 27 per cent, 
and less than 1 per cent by lines and dip nets. By way of comparison 
it may be noted that in the previous year the trap catch was 31 per 
cent, the seine catch was 27 per cent, the gill-net catch was 41 per 
cent, and the proportion by lines and dip nets practically the same as 
in 1915. The most notable feature of this is a decrease in 1915 of 
14 percent in the proportionate gill-net catch, which must be accounted 
for by reason of the lessened run of salmon in western Alaska where 
the catch is chiefly by gill nets. This proportionate decrease was 
offset by a proportionate increase of over 11 per cent caught by 
traps and more than 2 per cent in seines. The following table 
shows the proportionate catches by districts by the three principal 
forms of apparatus:

The total catch of salmon of all species in the commercial fishery 
of Alaska in 1915 numbered 63,537,244 as against 54,651,915 in 
1914, a gain of 8,885,329. In southeast Alaska there was an increase 
of about 15,000,000 salmon, but this was offset by decreases of more 
than 1,000,000 in central and about 5,000,000 in western Alaska 
as compared with 1914. In 1915 there were gains of approximately 
14,200,000 humpback, 110,000 king, and 13,000 coho salmon, while 
the number of reds decreased 3,950,000 and chums fell off 1,450,000.
