Hall, A.E., Jr., and Oliver R. Elliott 



1954. Relationship of length of fish to 



incidence of sea lamprey scarring 

 on white suckers, Gatostomus 

 commersoni , in Lake Huron. 

 Copeia 1954, No. 1, pp. 73-74. 

 Percentages of white suckers with 

 lamprey scars at various lengths 

 were: 5.0-10.9 inches, 11.0; 

 11.0-14.9 inches, 40.1; 15.0-20.9 

 inches, 70.6 percent. Incidence of 

 multiple scars also increased with 

 length of fish. These relations are 

 attributed to: mechanical difficulty 

 of lamprey attachment to the smaller 

 fish; greater ability of the larger fish 

 to survive attack; greater length of 

 time larger fish have been exposed 

 to attack. 



Comments on the unique value and 

 importance of the Great Lakes fish- 

 eries, explanation of decreasing 

 productivity as the result of overfish- 

 ing, and statement that adequate and 

 uniform regulations are needed to 

 conserve and restore the stocks. 



1938. The ineffectiveness of regulation 



of the Great Lakes fisheries by the 

 individual states. Proc. Great 

 Lakes Fish. Conf., Detroit, Mich., 

 Feb. 25-26, 1938, Council of State 

 Governments, pp. 48-60. 

 Review of bacteriological and limno- 

 logical studies refuting contention that 

 pollution has been a significant factor 

 in the decline of Great Lakes fisheries, 

 outline of evidence that overfishing has 

 been the major cause, and comments 

 on the impossibility of adequate regula- 

 tion under divided control by the 

 individual states.

 Summary of arguments in support of 

 belief that overfishing caused depletion 

 of Great Lakes fisheries, review of 

 past failures to attain adequate regula- 

 tions through voluntary cooperation 

 of state and provincial agencies, and 

 recommendation for establishment of 

 central control by means of inter- 

 national treaty.

 Lake Erie under the three general 

 divisions: analysis of statistics of 

 yield in relation to fishing intensity; 

 life -history studies (age, growth, 

 mortality, migration, food, • ■ •) of 

 important species; limnological and 

 ecological inquiries with special refer- 

 ence to pollution problems.
