INTRODUCTION 



It is gratifying to report an all-time high record for the distribu- 

 tion of fish and eggs from the hatcheries operated by the division 

 of fish culture during the fiscal year 1930. The division submits 

 this report with the full knowledge that a detailed analysis of the 

 various items comprising this huge total is necessary to present 

 properly a picture of the real significance of the operations. 



The popular conception of the bureau's fish-cultural work, based 

 only upon a limited knowledge of the game-fish hatcheries in the 

 interior and the distribution of these species on private applications, 

 must be overcome. It is essential to make the fact known that the 

 bureau's fish-cultural activities are not alone designated for the bene- 

 fit of the angler and the casual fisherman but also for the purpose of 

 furthering an important industry and for augmenting the food 

 supply of the Nation. 



When the analysis of the distribution records shows an output of 

 over 6,000,000,000 cod, haddock, pollock, flounder, mackerel, etc., the 

 question may arise as to the utility of this activity. It should be 

 borne in mind that the three marine stations propagating these 

 forms are operating at a negligible cost, not greatly in excess of the 

 cost of buying the trout food utilized at the game-fish hatcheries. 

 Again, in considering items of over 150,000,000 each of whitefish and 

 pike perch the fact should be kept clearly in view that the stations 

 in the Great Lakes area propagating these forms also are propa- 

 gating other commercial forms as well as large numbers of game 

 fish, particularly trout, during a period of the year. It has been 

 stated in previous reports that no definite evaluation of the results 

 attained from the operation of Federal hatcheries is possible. Dur- 

 ing the past year the passage by Congress of a 5-year expansion 

 program, with over 30 items providing for the expansion of existing 

 fish-cultural activities or the establishment of new ones, is an indica- 

 tion of the conviction of that body relative to the value of Federal 

 fish-cultural work. Such conviction on the part of Congress is, of 

 course, to a great extent, a reflection of the sentiment and viewpoint 

 of the country at large, which viewpoint is further attested by the 

 constantly increasing flood of applications for game fish.
