Table 1. --Exploratory fishing effort in southern Lake Michigan by cruise and year, 1962-65 



drags were made at the 5- fathom interval. 

 Only 19 drags, or less than 2 percent of the 

 total fishing effort, were in 7 fathonns or less. 

 At depths from 10 to 70 fathoms the coverage 

 was more complete (table 2). 



The fishing effort by port was unequal, and 

 not all ports were visited on each cruise. 

 Muskegon, Mich., and Grand Haven, Mich., 

 were visited only at the beginning of the study. 

 Milwaukee was visited only in June 1962 and 

 July 1964. Racine was also visited infre- 

 quently because it is near Waukegan. The 

 ports near the areas covered intensively 

 were Ludington, White Lake, Saugatuck, and 

 Benton Harbor on the east shore and Wauke- 



gan, Port Washington, and Manitowoc on the 

 west shore. The total effort was 444 drags off 

 the east shore and 354 drags off the west 

 shore. The large number of drags off Luding- 

 ton and Manitowoc was because of the inclu- 

 sion of this cross-lake transect in operations 

 that were concerned primarily with explora- 

 tions of northern Lake Michigan and Green 

 Bay. A large number of drags were also made 

 off Saugatuck, which is the home port of the 

 Kaho . (table 3). 



Because of stornns very little fishing was 

 possible during January and February (table 4). 

 During the remaining 10 months at least two 

 depth series were made each month.
