BULLETIN OF THE BUREAU OK FISHERIES. 



In order to counteract the effect of the very exhausting fisheries of the 

 Great Lakes, the Government has for many years maintained hatcheries in 

 that region, and in 1908 operated 6 belonging to the United States and 2 

 belonging to the State of Michigan. The fishes to which attention is given are 

 those which enter most largely into the catch of the fishermen, namely, the 

 whitefish, cisco, lake trout, and pike perch, the annual output of which now 

 exceeds one and one-half billions. Under arrangement with the Canadian 

 authorities, 2 egg-collecting stations for whitefish, cisco, and lake trout are 

 maintained at points in Ontario.

& Interior station, headquarters of the fish-cultural work in Michigan, conveniently located, and place where most of 

 the lake-trout eggs are hatched. 



c Hatcheries belonging to State of Michigan, leased by Bureau of Kisheries. 



The hatcheries on the rivers and lakes of the Pacific coast region are devoted 

 almost exclusively to the various salmons. In California, where the Bureau 

 established a salmon hatchery as early as 1872, there is one central or main 

 station, at Baird, on the McCloud River, with important collecting and eyeing 

 stations on two other tributaries of the Sacramento. In Oregon a central 

 hatchery at Oregon City, on the Willamette River, has three subhatcheries on 

 tributaries of the Columbia in Oregon and Washington and three subhatcheries
