454 U.S. BUREAU OF FISHERIES 



OUTPUT 



The hatchery production and distribution for the fiscal year 1933 

 was in excess of that of 1932, the increase being approximately 1.8 

 percent. The total output of eggs, fry, and fish of all sizes was 

 7,202,155,625. This increase was achieved in spite of the reduction 

 in the appropriation for hatchery operations, and represents a more 

 intensive use of existing facilities, together with expansion and im- 

 provement at the older stations and the operation of several new 

 auxiliaries and rearing units. It is especially gratifying that the fish 

 in the category of fingerlings were distributed in greatly increased 

 numbers over the previous year. The output of this larger stock 

 amounted to 182,338,625, an increase over last year of 22.7 percent. 

 The percentage of the various groups represented a considerable 

 change from the previous year. Game fishes accounted for approxi- 

 mately 2 percent of the total and the bulk consisted of 5 marine 

 species, amounting to 86.7 percent of the entire output. Commercial 

 species of the interior waters represented 8.5 percent ; while the anadro- 

 mous forms, those fish which migrate from salt water to fresh water 

 for spawning and are largely of a commercial classification, represented 

 2.7 percent; the balance, less than 1 percent, comprising various mis- 

 cellaneous forms. This represents an increase in the game fishes, an 

 increase in the marine varieties, and a drop for both the commercial 

 species of the interior watere and the anadromous types. The figures 

 for output include the fishes salvaged from the overflowed areas in the 

 upper Mississippi River, including those which are replanted directly 

 in the waters of the river itself and the very small percentage which is 

 distributed to more distant points. Summarizing, 18 individual 

 species were produced in larger numbers than during the previous year, 

 and the details are tabulated above. 



COOPERATION WITH OTHER CONSERVATION AGENCIES 



The existence of an International Association of Game Fish and 

 Conservation Commissioners, comprising the fish and game authori- 

 ties of most of the States, the Dominion of Canada, and some of the 

 Canadian Provinces, demonstrates the importance attached to con- 

 certed action in meeting mutual problems. Cooperation is a potent 

 force in fisheries conservation and the Division of Fish Culture has 

 had the fullest possible recourse to the benefits arising from joint 

 deUberation and action with agencies engaged in like activities. While 

 one of the primary original functions of the division was to assist the 

 States in maintaining fish resources, many of the States have now 

 developed to a point where their efforts can be advantageously 

 coordinated with those of the Bureau. 



Much of the common effort is a result of the contacts maintained by 

 the Bureau's fi^eld employees in charge of the hatcheries with the 

 State fish and game personnel. No formal agreements or programs 

 are necessary to enable these individuals to take advantage of various 

 opportunities for good management requiring the jouit use of equip- 

 ment, etc. As the Bureau's appropriations have decreased it is 

 becoming more vital that the States undertake to supplement Federal 

 fish-cultural work by contributing in one form or another to the 

 support of the propagation activities, and especially by acting as a 

 distributing agency for the fish produced in the Bureau's hatcheries.
