REPORT OF THE COMMISSIONER OF FISHERIES. 9 
ous marine species. Other fishes, however, which in the early days 
of fish culture also were planted soon after hatching, are now being 
held for longer and longer periods as the facilities for rearing are 
improved; and a conspicuous feature of the recent operations is the 
greatly increased percentage of fishes liberated as fingerlings and 
yearlings. The fishes which require this treatment are the salmons 
and trouts, which have a large, slowly absorbed yolk-sac, the carrying 
of which renders them more or less helpless and a ready prey to 
their natural enemies, and the fresh-water basses, which are espe- 
cially adapted for pond culture. In the fiscal year 1918, over 
168,000,000 fish were distributed by the Bureau as fingerlings, year- 
lings, and adults, this being by far the largest output of such fish, 
both in actual number and in percentage. The year 1917, which 
established a record in this respect, showed only 82,000,000 fishes 
distributed as fingerlings, yearlings, and adults. It should be under- 
stood that fishes stranded on the overflowed lands along the Missis- 
sippi River and tributaries and rescued by the Bureau’s agents are 
included in the foregoing figures. 
There follows a summarized statement of the output of the Bureau 
in 1918:
