body length from tip of nose to tip of tail, 

 allowed to escape in previous years, were killed 

 in 1969. The animals were killed each week 

 from 25 June to 1 August Monday through 

 Saturday beginning at 6 a.m. on St. Paul 

 Island and Mondays, Wednesdays, and Fridays 

 beginning at 9 a.m. on St. George Island. 



We sampled 20 percent of the males killed 

 22-26 July for age and body length to continue 

 a study of the relation between body length and 

 abundance. 



No effort was made to kill seals on inacces- 

 sible hauling ground areas such as Zapadni 

 Point and parts of Ardiguen and Gorbatch 

 Rookeries, or to frighten them away from these 

 areas. 



A kill of 38,678 males in ages 2 to 6 included 

 32,621 taken on St. Paul Island and 6,057 from 

 St. George Island (tables A-l to A-4). Trends 

 in the availability of 3- and 4-year-old males 

 taken in these kills to 31 July are given in fig- 

 ure 3 for St. Paul Island and in figure 4 for 

 St. George Island. The age composition of 

 the kill on each island was determined daily 

 by rookery from right upper canine teeth 

 collected from 20 percent of the males killed. 



Table 1 and figure 5 give the kill of males 

 on the Pribilof Islands from year classes 1947 

 to 1967.
