The foregoing output may be conveniently classified on the follow- 

 ing geographic basis, which agrees quite closely with the general 

 character of the operations of me hatcheries: 



Marine species of the Atlantic coast 3, 646, 827, 048 



Migratory species of the Atlantic coast 333, 322, 576 



Fishes of the Great Lakes 926, 201, 687 



Migratory fishes of the Pacific coast 206, 173, 456 



Fishes of the interior waters ... 46, 438, 526 



Total '. 5, 158, 963, 293 



It is possible to record a further reduction in the unit cost of fish- 

 cultural operations. Taking into consideration all expenditures 

 chargeable to fish culture and fish distribution, together with the 

 salaries of all employees in the fish-cultural service, the cost of fish 

 produced and planted in 1917 was $114.46 per milhon, as against 

 $117.86 in 1916, $131.65 in 1915, $146.36 in 1910, and $239 in 1905. 

 This record is noteworthy in view of the increased cost of all supplies, 

 materials, and temporary labor, and indicates increased efficiency and 

 economy.
