XXVII -REPORT OF DISTRIBUTION" OF FISH AND EGGS BY THE 

 U. S. FISH COMMISSION FROM JANUARY I, 1886, TO JUNE 30, 

 1887.* 



By M. McDonald. 



The aggregate number of fish and eggs distributed by the U. S. Fish 

 Commission, as collated from the reports of stations, iu the period 

 comprised between January 1, 1886, aud June 3, 1887, was 210,G28,413. 



The actual number distributed, however, was several hundred thou- 

 sand less than this, the discrepancy resulting from the fact that the 

 eggs of Salmonidae produced at one station have been transferred to 

 and hatched out at other stations and consequently have been reported 

 twice, once as eggs aud again as fry or older fish. The aggregate dis- 

 tribution by species is shown in the following summary, from which it 

 will be seen that the whitefish, the shad, and the carp still constitute 

 the main features of the work of the U. S. Fish Commission.
