sea, homing tendency, and commercial value 

 of skins by age and sex. Fur seal pups of both 

 sexes have been tagged and checkmarked 

 nearly every year on St. Paul Island since 1947 

 and on St. George Island since 1956. Yearling 

 fur seals, primarily males, were first tagged 

 in 1961. This section gives the number of tags 

 and marks recovered from male and female 

 seals killed on the Pribilof Islands in 1965 

 and discusses the techniques that were used in 

 tagging and marking pups and in selecting 

 yearlings for tagging on St. Paul Island. 



Tag recoveries .-- Tagged seals killed in 

 1965 were taken only if within the limits set 



for killing all seals. The limits for taking 

 males on both Islands were from 42,0 inches 

 (106.7 cnn.) long to, but not including, those 

 with nnanes. All females driven with the males 

 were taken. During the special kill of females 

 on St. Paul Island 23-27 August, only those with 

 black or mixed black and white vibrissae were 

 killed. All females driven during the special 

 kill of females on St. George Island 16-27 

 August were taken, regardless of vibrissal 

 color. Possibly a few of the 65 tagged seals 

 taken on St. Paul for studies of fur value by 

 age and sex were outside the prescribed 

 limits.
