TABLE 8. — Percent age composition of female seals sampled from the kills, 



Pribilof Islands, Alaska, 1958-62 



were essentially alike, the two sets of data 

 were combined. In 1962, however, selective 

 killing on St. Paul Island for young females 

 during the July- August kill and for old females 

 during the September kill produced differences 

 in age composition, making it necessary to 

 list the samples separately. There was no 

 September kill on St. George Island in 1962 

 because the female quota was taken in August. 



Reproduction 



Gross reproductive condition was deter- 

 mined for a sample of 562 tagged and 917 un- 

 tagged females on St. Paul Island and for 200 

 tagged females on St. George Island. Sum- 

 maries of the reproductive condition of these 

 females are given in tables 9, 10, and 11. 

 Figure 3 show the reproductive condition of 

 tagged seals, by age class, sampled from the 

 August kill. Figure 4 shows the reproductive 



condition of female seals, by date and age, 

 sampled from the September kill. The prog- 

 ressive increase in percent post partum fe- 

 males, for each age class, is attributed to a
