WHITEFISH FISHERY OF LAKES HURON AND MICHIGAN 



303 



and 1891-1896 (1896 was the last of the earlier years in which the catch exceeded a 

 million pounds), was 1,464,000 pounds. (In the discussion of this section, yields will 

 be given to the nearest thousand pounds.) The period, 1897-1921, was one of rather 

 consistently low output, the catch of whitefish exceeding a million pounds in only 

 4 isolated years of the 22 for which there are records. The average annual yield for 

 this period was 885,000 pounds.

1 See appendix A for list of years in which the Lake Michigan total includes the catches in the waters of Illinois and Indiana. 



2 Includes blackfins, longjaws, and pilot* (Menominee whitefish); the total for the lake in 1890 does not include the catch of these three species 



3 Includes pilots; the totals for the lake include only the pilots from the State of Michigan waters.
