446 U. S. BUREAU OF FISHERIES

EGG COLLECTIONS 



The commercial fisheries of the Atlantic coast and the Great Lakes 

 are the principal sources of supply for eggs for the bureau's work. 

 Vast numbers of the eggs available in these fields would be wasted 

 were it not for the efforts put forth by the bureau to conserve them. 

 In some cases the eggs are planted on the spawning grounds imme- 

 diately after fertilization is accomplished, but whenever conditions 

 make it possible they are transferred to hatcheries, incubated, and the 

 resulting fry liberated on suitable spawning grounds in the region in 

 which the eggs were taken. 



As compared with the statement of the preceding year, the records 

 of last year show a slight increase in the total number of eggs col- 

 lected, the most important increases being among the pike perch, 

 cod, and winter flounder.
