1937. The Great Lakes fisheries: their 

 proper management for sustained 

 yields. Trans. Am. Fish. Soc, 

 Vol. 66, (1936), pp. 131-138. 

 Recommendation of seven -point pro- 

 gram of regulation and research: 

 centralized control and discretionary 

 power; complete statistics properly 

 analyzed; research on causes of 

 fluctuations in abundance and yield; 

 identification of races and studies of 

 migrations; experimental investiga- 

 tions of gear; evaluation of artificial 

 and natural propagation; control over 

 introductions of exotic species. 



1937. The dispersal of smelt, Osmerus 

 mordax (Mitchill), in the Great 

 Lakes region. Trans. Am. Fish. 

 Soc, Vol. 66(1936), pp. 160-171. 

 Record of plantings of smelt in the 

 Great Lakes and a year -by-year ac- 

 count of the spread of the smelt 

 through Lakes Michigan, Huron, 

 Superior, and Erie . 



1937. The North Central States -Wildlife 

 Conference. The Prog. Fish.- 

 Cult., Bur. Fish. Memo. 1-131, 

 No. 26, pp. 15-19. 

 Review and evaluation of papers and 

 discussions at the conference on such 

 questions as: methods and values of 

 surveys; fish population s of "type" 

 waters and limitations of the type- 

 water concept; effectiveness of 

 artificial propagation and environmental 

 improvement . 



1937. The age, growth, and sex ratio of 

 the Lake Superior longjaw, 

 Leucichthys zenithicus (Jordan and 

 Evermann). Pap. Mich. Acad. 

 Sci., Arts, and Lett., Vol. 22 

 (1936), pp. 691-711. 

 Life -history study giving data on age 

 and size distribution, growth in length 

 and weight, growth compensation, sex 

 ratio, length -weight relationship, and 

 condition (a negative correlation demon- 

 strated between the growth rate and 

 condition of individual fish) . Protection 



of longjaw to end of sixth year of life 

 (total length, about .10. 3 inches) is 

 advocated. 



1937. Artificial propagation of commer- 

 cial fish of the Great Lakes. 

 Trans. 2ndN. Am. Wildlife Gonf., 

 pp. 605-612. (Reprinted with 

 slight changes of title and text in 

 The Progressive Fish-Culturist, 

 Bur. Fish. Memo. 1-131, No. 28, 

 1937). 



General discussion of the subject, with 

 emphasis on the facts that correlations 

 have not been found between fry plant- 

 ings and the later take of fish and that 

 fish-culturists have underestimated 

 the effectiveness of natural reproduc- 

 tion and also have failed to consider 

 the true loss of eggs to the lake (killing 

 of green fish, inefficient stripping, • • •) 

 attendant on artificial propagation. 



1938. Michigan's commercial fisheries 

 of the Great Lakes. Mich. Hist. 

 Mag., Vol. 22, pp. 3-39. 



Review of fishery from earliest to 

 modern times with respect to fishing 

 grounds, boats and gear (construction 

 and operation of different types 

 described), and trends of production. 

 Includes accounts of early statistical 

 and biological surveys and of modern 

 research programs and an analysis 

 of present-day problems of regulation 

 and management. 



1938. The extent of the depletion of the 

 Great Lakes fisheries. Proc. 

 Great Lakes Fish. Gonf., at Detroit, 

 Mich., Feb. 25-26, Council of State 

 Governments, pp. 10-17. 

 Presentation and discussion of charts 

 showing outstanding examples of col- 

 lapse in production in Lake Erie 

 sturgeon, Lake Superior whitefish, 

 Lake Huron yellow perch, • • • . 

 Stresses fallacy of use of total produc- 

 tion figures that do not reflect progres- 

 sive shift of species composition from 

 more valuable to coarse varieties or 

 show effects of exploitation of new 

 grounds or varieties (as in the recently 

 expanded lake herring fishery of Lake 

 Superior) .
