BUREAU OF FISHERIES XVII 
FISHERIES OF THE PACIFIC COAST STATES 
During the past year statistics, as collected by the Pacific Coast 
States, were compiled and supplemented by the bureau’s agents. 
These compilations included 1924 and 1925, and, with the statistics 
already published, there are available four successive years’ data, 
from 1922 to 1925, inclusive. 
On the basis of the most recent year, 1925, the fisheries of the 
Pacific Coast States employed 16,856 fishermen, 673 vessels of 13,361 
tons, and 5,424 motor boats. The total yield amounted to nearly 
611,000,000 pounds, valued at nearly $24,600,000. This is the largest 
yield on record. 
The salmon fishery, by far the most important in value, yielded 
139,848,020 pounds, valued at $10,149,961. Next im importance was 
the tuna fishery, which produced 54,776,970 pounds of albacore, tuna, 
skipjack, and bonito, valued at $4, 558,183. Third in importance was 
the halibut fishery, with 19,256,185 pounds, valued at $2,177,125. The 
sardine fishery ranked fourth, with 315,294,986 pounds, valued at 
$2,087,756. 
The total yield has increased successively from 405, ay 000 pounds 
in 1923 to 474,000,000 in 1924 and to 611,000,000 in 1925. The value 
increased from $19,000,000 to $20,000, 000 and to $25, 000. 000 in these 
same years, respectively. Most of the increased poundage was 
achieved in the sardine fishery, which almost doubled its yield during 
the three years. The sudden spurt in value between 1924 and 1925 
is due to the unusually large catches of salmon and tuna. 
FISHERIES OF THE GREAT LAKES 
With the cooperation of the Tariff Commission, statistics of the 
yield of the Great Lakes fisheries originally collected by the States 
were compiled for the years 1913 to 1925, inclusive. During this 
period the United States yield fluctuated between 68,000.000 and 
109,000,000 pounds. The average yield during the first half of this 
period (1913 to 1919) was 94,195,000 pounds per year, while during 
the last half (1920 to 1925) it was only 78,161,000 pounds. This 
marked decline has been especially noticeable among some of the 
most valuable and most sought-for fishes, principally whitefish, her- 
ring, chubs, ciscoes, and sturgeon. 
TECHNOLOGICAL INVESTIGATIONS 
In its technological work the Bureau of Fisheries is endeavoring 
to improve present practices and to dev elop new equipment, methods, 
and products within the fisheries industries and to bring about proper 
utilization of wastes and by-products. Inv estigations | are made and 
science applied to the various problems. Results are then made 
available to the industry, and their application is directed until they 
become an integral part of the same. The fisheries industries offer 
a very fruitful ‘field for work of this nature. Rapid progress in in- 
dustry (and this applies particularly to the fisheries industries) de- 
pends largely upon such work, combined with the application of 
sound business principles,
