respectively) were taken on St. Paul Island in

Tag Recoveries and Tagging 



Tag Recoveries . --Except for a few tagged 

 animals taken for experimental use, tagged 

 male and female seals were not killed pur- 

 posely, but rather, were taken only if thev 



were within the limits described on pages 3 

 and 8 of this report. 



A total of 4,205 tags were recovered from 

 seals tagged as pups; 1,890 checkmarks from 

 seals that had lost their tags were recorded. 

 These data are summarized in table 8 by sex, 

 age, and island, and are given in more detail 

 in appendix table 14. The homing tendency 

 of tagged male and female seals is shown 

 in table 9 by age and in table 10 by rook- 

 ery.
