CONCLUSIONS 



Immature herring were tagged experi- 

 mentally with loops of polyvinyl chloride 

 tubing during the I960 Maine fishing season. 

 A total of 8,300 tagged herring released in 

 units of 100 to 500 gave a recovery rate vary- 

 ing from to 5 percent. The greatest known 

 distance to recovery was 50 miles; greatest 

 speed of travel was 10 miles per day; and the 

 longest time to recovery was 391 days with 

 an average recovery time of 18 days.
