4.-THE FISHERIES OF THE GREAT LAKES. 



INTRODUCTORY NOTE. 



The fisheries of the Great Lakes, by reasoji of their great extent and 

 tlie energetic measures taken by the General Government and tlie 

 various States to maintain and increase tlieir productiveness, have 

 received an unusual amount of public attention, which has been increas- 

 ing during late years, owing to the more extensive fish-cultural opera- 

 tions carried on, the threatened depletion of some of the lakes, due to 

 wasteful methods or overfishing, and the growing necessity for concur- 

 rent action on the part of the several States and Canadian Provinces for 

 the preservation of this important industry. 



This Commission has aimed to keep well informed as to the status of 

 the lake fisheries and has within a comparatively short time conducted 

 two thorough investigations of the industry, viewed from the stand- 

 point of the economic fisherman. The first canvass of this region, since 

 the census of 1880, was made in 1885; the results of this couiprehensive 

 investigation of the history, apparatus, methods, and statistics of the 

 fisheries were published in a report entitled " Review of the Fisheries 

 of the Great Lakes in 1885" (330 pages, 7 charts, and 37 illustrations of 

 fishes, api^aratus, etc.). 



The present paper represents the results of q^n Investigation of the 

 commercial fisheries of the Great Lakes conducted by this Commission 

 during the fiscal year 1892, and illustrates the condition and extent of 

 the industry during the year ending December 31, 1890. Notice of 

 the field work and a summarized account of the results of the inquiry 

 have appeared in my annual leport for 1892. The following agents 

 of the Division of Fisheries participated in the investigation and can- 

 vassed the regions specified: W. A. Wilcox and T, M. Cogswell, Lake 

 Superior; E. E. Race and U. P. Parker, northern, western, and eastern
