INTRODUCTION. 



During the fiscal year ended June 30. 1923. the bureau's fish-cul- 

 tural activities were confined necessarily to certain well-established 

 fields, it being impossible to extend the work into new territory 

 because funds were not available for the purpose. Unless increased 

 appropriations are allowed for the propagation and distribution of 

 food fishes, the work of the division can hardly be enlarged beyond 

 its present limits, and prospects at this time point to a gradually de- 

 clining output. Up to the present time the pre-war record of the 

 bureau has been more than maintained without any increase in the 

 funds applied to the work. However, this high standard of efficiency 

 can not be continued indefinitely in the face of an increase in the cost 

 of all materials and labor entering into the work, the prices of 

 practicallv everytliing used in connection therewith being approxi- 

 mately 67 per cent higher than in 1917. 



FISHES OF INTERIOR WATERS. 



The demand for fish for stocking interior waters of tlie country 

 increases at the rate of about 10 per cent a year. The value of these 

 interior fislieries can hardly be overestimated. They add millions 

 Oi pounds annually to the Nation's food supply, and in many locali-
