OUTPUT. 



The combined work of the fish-cultural stations and the rescue 

 crews during the year resulted in a net output of 5,125,101,320 fish 

 and fish eggs for distribution as compared with 4,962,489,405 for the 

 year previous. Some points of interest to be noted in comparing the 

 appended tables summarizing by species the net outputs for the fiscal 

 years 1922* and 1921 are an increase in the fiscal year 1922 of approxi- 

 mately 50 per cent in the output of fingerling fish and of about 3 per 

 cent in the aggregate output, accomplished with a decrease of about 

 6 per cent in operating costs. The cost per million of the fish and 

 fish eggs produced during 1922 was $120.36 as against $128.06 per 

 million for 1921. Of the total output for 1922 all but approximately 

 35,000,000 may properly be classed as of direct commercial im- 

 2)ortance.
