result of overfishing with bull nets 

 (deep gill nets) in 1923 and 1924 when 

 abnormal weather (heavy storms) had 

 concentrated the stocks within a small 

 area of deep water in eastern Lake 

 Erie.

 and legislation of the commercial fish- 

 eries of Lake Erie. Trans. Amer.Fish. 

 Soc. 62:100-107. 



Description of experimental design 

 and presentation of selected data to 

 show type of results from studies of 

 relation of mesh size to release of 

 undersized fish and catch of legal- 

 sized fish of several species. Recom- 

 mendations are given on legal specifi- 

 cations for trap net meshes.

Review of 1927-32 activities with 

 emphasis on the practical nature of the 

 program and with particular reference

 fishes. The Fisherman (Grand Haven,

1933a. Preliminary report on investigation 

 of chubnet meshes in Lake Michigan. 

 The Fisherman (Grand Haven, Mich.) 

 2(4):3-4, 8. 



Condensed summary of numbers and 

 pounds of lake trout and chubs per lift 

 of chub gill nets of different mesh size 



in different regions of Lake. Abundance 

 of chubs and small trout on Michigan 

 side of Lake, 2.7 times that in Wis- 

 consin, was attributed to use of larger 

 meshes in Michigan nets. Uniform adop- 

 tion of 2-3/4-inch mesh was recom- 

 mended.

 Michigan. Mich. Tradesman 52(2674): 

 25. A letter. 



Review of the development of the 

 deep trap net fishery showing fronn 

 statistical records the dangerous in- 

 crease of production of whitefish re- 

 sulting from the use of the gear and 

 the disastrous depletion of grounds 

 fished intensively by deep trap nets. 

 Advocates specific restrictive regula- 

 tions.

 veys. Trans. Amer. Fish. Soc. 64:107-

Recommendation of the question- 

 naire as a cheap and efficient means 

 of obtaining biological and statistical 

 data on fish and fisheries and of learn- 

 ing the views of the industry on ques- 

 tions of management and regulation. 

 Includes examples to demonstrate the 

 reliability and usefulness of data from 

 questionnaires.
