Summary, by States, of the distribution of fish, fiscal year 1939_________ 596 
INTRODUCTION 
In announcing the gross production of 8,024,540,685 fish and eggs 
at Federal fish hatcheries during the fiscal year 1939, the Bureau 
recognizes that the significance of such a contribution is obscured 
without further analysis in the form of a report of hatchery production 
in terms of pounds of fish. However, no such treatment can be fol- 
lowed in handling the billions of fry and eggs of commercial marine 
species, but it is expected to place in operation during the fiscal year 
1940 a system of weighing all the game fish distributed. Again, the 
production of a few hundred thousand fry or fingerlings of a species 
which is subject to intense fishing pressure, such as certain species 
of Pacific salmon, is of greater importance than the distribution of 
millions of fish of lesser economic value, such as the yellow perch. 
It may well be asked why these figures are not reversed and maximum 
production maintained with the varieties which exhibit the greatest 
need for restorative measures. This question can be answered by 
pointing out that, broadly speaking, artificial propagation must be
