LAKE FISHERIES 



The yield of the fisheries of the Great Lakes including the inter- 

 national lakes of northern Minnesota during 1930 amounted to 

 94,947,642 pounds, valued at $6,050,267. This is an increase of 11 

 per cent in quantity, but a decrease of 11 per cent in value as com- 

 pared with the catch and its value for 1929. These fisheries gave 



12 With reference to the figures published in this section the reader should refer to that section in the 

 latter part of the book entitled " Statistical survey procedure" which gives in detail methods for collecting 

 statistics, compilation practices, and conversion factors. This is most necessary for a complete understand- 

 ing of the statistics presented herewith. 



The statistics of the catch presented herewith were obtained largely from the records of the various State 

 fishery agencies and from the Dominion Bureau of Statistics, Ottawa, Canada. The data for the operating 

 •units (fishermen, vessels, boats, and gear) of the United States were obtained largely by bureau agents in 

 a special canvass; although State records in sev^eral instances were very helpful in this work. 



In all cases the statistics collected are for the calendar year, except for Lake of the Woods, Rainy Lake, 

 and Lake Namakan in Minnesota, which are for two seasons. For Lake of the Woods the seasons are from 

 June 1 to Nov. 1 and Dec. 1 to Apr. 1, and for Rainy and Namakan Lakes from May 15 to Nov. 1 and Dec. 1 

 to Apr. 1. The catch for these two seasons, in the order named, have been combined to constitute a year. 

 The quantity of fish taken in these lakes between Jan. 1 and Apr. 1 amounted to less than 3 per cent of the 

 ;!otal catch of these lakes in 1927.
