seals ^ 2 years old on St. Paul Island in 1969, 

 68.5 percent were recovered (table 26). Al- 

 though 600 males were tagged, only 555 were 

 effective because some of the seals lost their 

 tags. Two tagging pliers were found to be 

 faulty after the June 1969 tagging period. Tag 

 losses were: 18, 15, 2, and 40 percent on seals 

 tagged on four hauling grounds in June 1969; 

 4, 1, 2, and 3 percent on seals tagged 1-5 July; 

 and 1, <1, 1, and 5 percent on seals tagged 14- 

 17 July. 



The interval between tagging and recovery 

 of tags ranged from 1 to 40 days. Forty-six 

 percent of the seals tagged were recovered 

 within 7 days, after which the recoveries 

 dropped sharply (table 27). On the basis of 

 a standard recovery interval of 15 days (the 

 interval between the last day of tagging on 17 

 July and the end of the kill on 1 August) , 53, 

 54, and 56 percent of the seals tagged 20-23 

 June, 1-5 July, and 14-17 July, respectively, 

 were recovered in 1969. 



Tagged seals showed a strong tendency to 

 return to the hauling ground of tagging — 74
