TABLE 15. --Release Jnd recovery--Michigan--Continued 



'With drags, 21; without drags. 30; no data, 6. 

 'Based on recoveries within the year of release 



below the averages. It is also unusual that 

 nearly all bottles were located somewhere 

 near or between the above-mentioned ports. 

 The northernmost bottle was found 2 miles 

 north of the Big Sable Point and the southern- 

 most caught in a pound net 4 miles south of 

 Grand Haven. Five bottles moved northeast- 

 ward, five eastward, and the rest in a southerly 

 direction. Thirty-three (87 percent) of 38 

 bottles held their drags. 



Grand Haven to Sheboygan 



Thirty-eight bottles (table 21) were released 

 June 23, 1932, along this transect (fig. 18), 

 and 27 (71 percent) were recovered. Only 

 seven (26 percent) retained the drag. Not a 

 single bottle was found on the west shore. 

 Sixteen floated southeast and 11 northeast, 

 distributing from 1 mile north of Macatawa, 

 Michigan, to 12 miles south of Frankfort, 

 Michigan. Although all of the bottles, excluding 



the one found after 335 days, were picked up 

 between 8 and 48 days, averaging 29.7, those 

 released toward Sheboygan were recovered 

 during the later days because of greater dis- 

 tances. For example, the averages of the 

 first 5 bottles dropped near Grand Haven 

 were 12.6 days and 12.8 miles, the central 

 bottles averaged 28.2 days and 35.2 miles, 

 and the last 8 bottles showed 42.9 days and 

 60.6 miles. The minimum miles ranged from 

 5-84 and averaged 37.6. 



Sheboygan to Sturgeon Bay 



Thirty-three bottles (table 22) were released 

 on June 24, 1932, along the Wisconsin shore 

 (fig. 19). All recovered bottles were found 

 along the eastern coast of the lake except one 

 that was discovered 445 miles distant in Lake 

 St. Clair on June 6, 1942. Eighteen floated 

 northeast (one entering Grand Traverse Bay) 

 and seven moved southeast. The 24 bottles
