ACKNOWLEDGMENTS 



We thank the hundreds of people (scientists, techni- 

 cians, crew members, and vessel owners and operators) 

 who helped get the tags out and the recoveries in. Some 

 are mentioned in the text; others (including the many 

 "tunaboat observers" who released the tags listed in Ap- 

 pendix 2) are not. We thank W. H. Bayliff who proposed 

 the initial design of the tagging shute. We also thank J. 

 G. Jennings, J. M. Coe, T. Quinn, V. I. Gallucci, R. L. 

 Brownell, Jr., and W. H. Bayliff, for criticizing the 

 manuscript. Unpublished data were furnished by the 

 Inter-American Tropical Tuna Commission through the 

 courtesy of C. J. Orange. R. Butler and N. K. Wiley pro- 

 vided invaluable assistance with data processing.
