the Fisheries Research Board of Canada, the Food 

 and Agriculture Organization of the United Na- 

 tions, and many other national and private re- 

 search organizations have assisted in the promot- 

 ing of the tagging of fishes, and the return of tags 

 with recapture data. 



The tagging results were made possible by the 

 thousands of anglers, captains, and mates who 

 have tagged, and released many of their catches, 

 the commercial tuna fishermen who have cooper- 

 ated with the tagging program, and the clubs, 

 committees and individuals who have encouraged 

 tagging. We regret that space does not permit 

 individual acknowledgments here; the major par- 

 ticipants are listed in the informal progress re- 

 ports which are issued periodically by the Woods 

 Hole Oceanographic Institution. The press and 

 the broadcasting media have also done much to 

 encourage tagging and the return of tags.
