THE UNITED STATES BUREAU OF FISHERIES. 1395' 



of rainbow trout fingerlings, yearlings, and adults, 44,800 were donated to 

 Maryland and 5,000 to Nebraska. 



The oyster-producing States more than any others have asked for the 

 assistance of the Bureau's scientific staff. In Alabama, Florida, lyouisiana, 

 Maryland, North Carolina, South Carolina, and Texas extensive surveys have 

 been made or are being made, the oyster grounds charted, biological and phys- 

 ical conditions studied, and the path to successful cultivation pointed out. In 

 North Carolina the declining shad fishery was recently investigated in both its 

 natural history and statistical aspects by the Bureau at the request of the state 

 authorities. State hatcheries have frequently called for aid in the study and 

 treatment of epidemics among the fry and young fish. The results achieved 

 in these various instances will be referred to elsewhere. 



International courtesy has prompted the donation of American fish eggs 

 to foreign governments, and the hardiness of such eggs and the facility with 

 which they may be transported out of water for long distances have resulted 

 in the establishment of some of the best of our food and game fishes in distant 

 lands. Thus the brook trout and other American salmonoids are now thriving 

 in Argentina; the brook trout, the rainbow trout, and the black bass are widely 

 distributed in Europe; the rainbow and brook trouts are found in several 

 Japanese lakes; and some of the finest trout fishing in the world is afforded 

 by the rainbow trout in New Zealand, where also the chinook salmon, the 

 blueback salmon, and various other American fishes are now flourishing. Dur- 

 ing the past year about 4,000,000 eggs of salmons and trouts were shipped 

 abroad. When the Bureau is unable to supply such requests from its own 

 stock, it acts as agent in the purchase from private fish-cultural establishments, 

 supervising the packing and the transportation to the point of embarkation. 



PUBLICATIONS. 



The 65 large volumes which represent the United States Bureau of Fish- 

 eries on library shelves are not the mere routine report or annual statement of 

 funds disbursed and duties discharged. The scientific study and the practical 

 experiment which are the foundation of the Bureau's work yield results of 

 manifold interest and far-reaching significance, and such results are corre- 

 spondingly fruitful of discussion. The dissemination of the knowledge they 

 afford is, moreover, a recognized function for which the periodical document 

 issue is the established medium. The subject-matter of these volumes is thus 

 coextensive with the scope of the operations of the Bureau — it is biological, 

 fish-cultural, and commercial, treated from standpoints both technical and 

 economic. The names of J. A. Allen, Baird, Bean, Bumpus, Dean, Farlow, 

 Forbes, Gill, Gilbert, Goode, Jordan, Rathbun, Ryder, Verrill, and numbers 

 of other well-known biologists give the publications authority in science; and
