PROPAGATION AND DISTEIBUTION OP FOOD FISHES, 1924 369 

 Shipments of fish eggs to foreign countries, fiscal year 1924 



EGG COLLECTIONS 



The records show a large increase in egg collections over those of 

 the preceding year. This excess was made possible by the unusual 

 degree of success attained in the work with the commercial fishes, the 

 collections of the marine species alone exceeding those in 1923 by 

 over 800,000,000. An important factor in this connection was the 

 work conducted in connection with the fisheries on Georges Bank, 

 these operations yielding nearly 197,000,000 eggs in addition to those 

 obtained for the hatcheries. In its prosecution spawn takers detailed 

 by the bureau accompany the vessels to these distant fisheries to take 

 and fertilize eggs of the cod and haddock, which would otherwise be 

 discarded, and plant them on the natural spawning areas. 



Other notable increases in the yearly collections were in those of 

 the pike perch, yellow perch, and black-spotted trout in the Yellow- 

 stone National Park, and of Loch Leven trout in the Meadow Creek 

 field.
