possible magnitude of error in the number of 

 males of each age killed in 1968, Differences 

 between adjusted and nonadjusted age composi- 

 tions were about 1 percent each for 3-, 4-, and 

 5-year-old males and 17 percent for 2-year- 

 old males (table 2). The adjusted number of 

 Z-year-old males was less than the nonadjusted 

 number. Adjusted numbers of seals killed are 

 not used in any of the calculations in this re- 

 port because the data are similar for ages 

 3, 4, and 5, and it is not known if the adjusted 

 or the nonadjusted age composition is more 

 representative of the true age composition. 



1/ We did not include 130 6-year-old males taken on the 

 Pribilof Islands 26 June to 5 August, nor 307 males killed on 

 St. Paul Island 3 and 5 August because the data for these seals 

 were incomplete.

FEMALES 



The 13,335 females killed on the Pribilof 

 Islands in 1968 were considered excess to the 

 number needed to maintain the production of 

 pups at the present level. St. Paul Island con- 

 tributed 10,544 females, and St. George Island, 

 Z,791. Right upper canine teeth from 30 per- 

 cent of the females killed were used to estimate 

 the age composition of the total kill (tables 

 A-5 to A-12). 



The kill began about 6 a.m. Monday through 

 Friday on St. Paul Island and about 9 a.m. 

 Monday, Wednesday, and Friday on St. George 

 Island. All females killed were taken from 



hauling grounds, and all females in the drive 

 were killed regardless of age or size. When the 

 kill of males ended 2 August on St. Paul Island 

 and 5 August on St. George Island, 1,233 and 

 173 females, respectively, had beentaken. The 

 relative size of each rookery was used as a 

 guide in killing the remaining 1 1,594 females 

 needed to achieve a quota of 13,000 (table 3). 

 A special effort was made not to exceed the 

 quotas on Reef, Polovina, and Staraya Artil, 

 three rookeries where females are extremely 

 accessible.

 classes 1943-67.
