INTRODUCTION 
The record level of hatchery production attained during the fiscal 
year 1936 was subject to a slight recession in 1937. The decline from 
a total of 8,170,000,000 fish and eggs to 7,919,000,000 was relatively 
insignificant for an enterprise which is influenced by many outside 
factors and is consequently liable to noticeable fluctuation in produc- 
tion. 
At the present time conservationists and sportsmen are greatly 
interested in the development of stream-improvement work and the 
conduct of stream surveys, both intended to provide a more rational 
policy of stocking the streams and lakes. These studies have resulted 
in detailed and elaborate stocking programs for thousands of miles 
of public waters. The promulgation of such programs emphasizes 
even more strongly the vital role of the hatcheries in maintaining 
sport fishing. The most carefully designed plan for fish stocking and 
conservation is utterly useless without the raw material in the form 
1 Administrative Report No. 33, Appendix IV to the Report of the U. 8. Commissioner of Fisheries for 
1937. Approved for publication Nov. 1, 1938.
