THE MAGNITUDE AND SCOPE OF THE FISH- 

 CULTURAL WORK OF THE U. S. BUREAU 

 OF FISHERIES, 19 JO 



By R. S. Johnson 



Fish-cultural operations were conducted at 35 permanent 

 stations, in connection with which field collecting stations 

 to the extent of 86 were operated, the work of the Bureau 

 extending into 32 states. Forty-two different species of 

 fresh and salt-water fishes were propagated at the various 

 stations, and large collections were made from the overflow 

 waters of the Illinois and Mississippi Rivers of fishes indi- 

 genous to that region. 



The total output of fish and eggs for the year amounted 

 to 3,231,462,579, exceeding the record year of 1909 by 

 124.330,668. 



Four hundred and forty-three million one hundred and 

 seventy-seven thousand eggs and 18,250 fishes were deliv- 

 ered to various state commissions, and 600,000 eggs of the 

 salmon and trout were shipped to foreign countries. The 

 fishes and eggs allotted to the state commissions were sent 

 into 18 states, the eggs being hatched under state auspices 

 and the resulting fry deposited in state or public waters. 



With reference to the fishes propagated, the regular 

 hatcheries may be classified as follows : 



Marine species 3 



River fishes of the eastern seaboard 5 



Fishes of the Pacific Coast S 



Fishes of the Great Lakes 7 



Fishes of the interior 15 



The conspicuous increases over the year 1909 were in 

 sockeye, silver and Atlantic salmon, lake trout, lake herring, 

 yellow perch, shad, cod, flatfish, and steelhead trout, the 

 production of the three latter species exceeding all pre- 

 vious vears.
