percent were recovered there (table 28) . Only 

 9 of 380 tagged seals recovered were taken on 

 St. George Island. The proportion of tagged 

 4-year-old males recovered on the hauling 

 ground of tagging was higher than that of 3- 

 year-old males, but not significantly so. 



Discussion of tagging. — Eighty percent of 

 the tags applied to seals in 1968 were recovered 

 in 1968 and 1969. If additional tags are re- 

 covered in 1970, a utilization rate of slightly 

 over 80 percent for these males is indicated. 

 The percentage of seals recovered during the 

 period in which they were tagged (20 June to 

 1 August) was similar in 1968 and 1969 (P = 

 0.76). 



The proportions recovered of tags applied in 

 late June of 1968 and 1969 and in mid-July of

1968 and 1969 to seals on accessible hauling 

 grounds were nearly equal (fig. 11) (P = 0.40 

 and P = 0.74, respectively). 



Total recoveries were significantly different 

 (P< 0.001), however, for tags applied on ac- 

 cessible hauling grounds on dissimilar tagging
