REPORT OF THE COMMISSIONER OF FISHERIES. 



As will be noted from the summary of distribution, the output of 

 fingerling fish of all species was 35 per cent smaller than that of the 

 j)revious year. This is largely accounted for hj the smaller number 

 of rescued fish handled as compared with that year. Shortage in the 

 general propagation fund also had its effect upon this branch of the 

 work, as large numbers of young fish can not be reared without in- 

 Yolving considerable expense for food and labor. 



During the fiscal year 1923 fish-cultural work was conducted by the 

 bureau in 33 States and in the Territory of Alaska, involving the 

 operation of 37 main stations and 32 auxiliaries, and the propagation 

 of over 40 species of food fishes. Consignments of e3'ed eggs of cer- 

 tain sjDecies were furnished on request to several foreign Govern- 

 ments, and in numerous instances allotments of eggs were transferred 

 to State hatcheries and other stations of the bureau as an economical 

 and efficient means of rehabilitating depleted waters. 



The bureau does not transfer eggs or fry of the important commer- 

 cial fishes to points remote from the source of collection, as the entire 

 available supply is needed for the maintenance of the fisheries in- 

 home waters. This applies especially to the Pacific salmons, to the 

 whitefish, lake trout, and pike perch of the Great Lakes region, and 

 to the shad and the marine species of the Atlantic coast.
