124 RURAL MICHIGAN 



It has become evident that the fidi supply of the 

 Great Lakes is diniinishing, and the great im- 

 portance of the industry has promoted the estab- 

 lishment of hatcheries both by the State and the 

 United States for the propagation of fish for planting 

 in the inland waters and in the Great Lakes. Hatch- 

 eries owned or operated by the State under the direc- 

 tion of the Michigan Fish (now Conservation) Com- 

 mission were located (December, 1920), at Paris, 

 Mecosta Connty ; Comstock Park, Kent County ; Hen- 

 rietta, Wexford County; Drayton Plains, Oakland 

 County; Detroit; Sault Ste. Marie; Grayling, Craw- 

 ford County ; and Bay Port, Huron County ; while 

 other hatcheries were under construction at Manis- 

 tique, Schoolcraft County in the Upper Peninsula; 

 Oden, Emmet County; Hastings, Barry County; 

 Benton Harbor, Berrien County; and Harrisville, 

 Alcona County. From these fish hatcheries during 

 the year 1920, the number of fish distributed through- 

 out the State aggregated 128,225,300, including fry, 

 fingerlings and yearlings. These included 12,132,- 

 000 l)rook trout (fry and advanced fry) ; 0,458,500 

 rainbow trout; 9,018,000 wall-eyed pike; 53,870,000 

 perch (fry) ; 18,000,000 whitefish (fry) ; and 891,- 

 000 lake trout (fry). During the past twenty years, 

 according to the superintendent and secretary of the 

 Michigan Fish Commission, most of the work of 

 fish propagation in the Great Lakes has been main- 

 tained by the United States Bureau of Fisheries, 

 which operates hatcheries in Michigan at North- 

 ville, Alpena, and Charlevoix. The list of species
