Aberdeen Fisher y Statistics. 5 



thg-n in tliat of the British trawlers, and the total value of the landings 

 by foreign trawlers is between one-sixth and one-seventh of the value 

 of all the trawled fish brought into Aberdeen. 



When we reviewed the statistics of the total landings of trawled 

 fish at Aberdeen up to the year 1904, it was pointed out that the total 

 quantity landed had increased nine-fold in the preceding 15 years, 

 and had rather more than doubled every 5 years. So rapid a rate 

 of increase could scarcely be expected to continue, and we now find 

 that it has taken just the nine years, from 1904 to 1913, for the total 

 landings of trawled fish at Aberdeen to be again approximately, but 

 not quite, doubled ; the quantity landed in 1904 was 1,280,000 cwts., 

 and that in 1913 (including landings by foreign vessels) was 2,190,000. 

 Dming the whole period, 1889-1913, that is to say in 24 years, the total 

 quantity of trawled fish landed at Aberdeen has increased sixteen-fold, 

 which rate of increase is obviously equivalent to a ^irocess of doubling 

 every 6 years (Table D). 



The total landings of all fish other than herring, sprat, etc. (that 

 is to say of demersal fish), caught by line and trawl in all Scotland, 

 have increased during the same period of 24 years from 1,345,000 to 

 3,296,000 cwts. — an increase of 145 per cent. This is equivalent to a 

 process of doubling in 18'6 years.
