No material changes were made in the methods heretofore em- 
ployed; but through the acquisition of additional knowledge of the 
conditions governing practical fish culture and the attainment of 
greater proficiency, the Bureau was enabled to further develop the 
resources at its command, extending its activities into new fields con- 
tiguous to those already covered, and materially increasing its out- 
put over that of any previous vear in its history. In attaining these 
results the funds available were not greater than those of 1914. 
While there were slight decreases in the output of some of the 
fishes propagated, there were substantial gains in some of the more 
important species. A partial list of the latter class includes catfishes, 
whitefish, lake herring, silver salmon, chinook salmon, dog salmon, 
steelhead trout, rainbow trout, blackspotted trout, brook trout, crap- 
pies, black basses, sunfishes, pike perch, and yellow perch. 
The output of the hatcheries devoted to the marine species of the 
North Atlantic coast, the commercial fishes of the Great Lakes, and 
the migratory food fishes of the Atlantic coast streams, which is al- 
ways far in excess of the- ‘rearing capacity of these stations, was de- 
posited on the natural spawning grounds within a few days after 
the hatching of the eggs. On the other hand, a considerable per- 
centage of the salmons, trouts, black basses, crappies, sunfishes, and 
catfishes was reared to the fingerling or ‘yearling stage before being 
distributed.
