REPORT 
OF THE 
COMMISSIONER OF FISHERIES. 
DEPARTMENT OF COMMERCE, 
Bureau OF FISHERIES, 
Washington, October 11, 1915. 
Sir: There is submitted herewith a report giving an outline re- 
view of the operations of the Bureau of Fisheries during the fiscal 
year ended June 30, 1915. 
PROPAGATION AND DISTRIBUTION OF FOOD FISHES. 
REVIEW OF THE OPERATIONS. 
The scope and magnitude of the Bureau’s operations in relation 
to the propagation and distribution of food and game fishes, and the 
bearing of this work on the maintenance of the fishery resources of 
the nation, are indicated by the following table, which shows an out- 
put of 4,288,757,800 fish and ova, an increase of 241,000,000 over the 
preceding year. 
The increased output was accompanied by a diminished unit cost 
of production and a very noteworthy increase in the number of fish 
reared to the fingerling and yearling stages. As improved facilities 
are gradually provided at the various stations, in accordance with 
the established policy of the Bureau, the rearing of certain kinds of 
fishes will be further and further extended, and the effectiveness of 
the fish-cultural work will thus be annually augmented. In 1915 the 
fish distributed as fingerlings, yearlings, and adults numbered over 
58,000,000, an increase of more than 150 per cent over 1914, made up 
largely of salmons, trouts, and basses.
