gradual shift from killing females from the 

 hauling grounds to killing those taken from 

 rookery fringes or from rookeries. 



The annual variations in pregnancy rates, 

 by age and island, are given in table 12 for 

 1956-62. There have been no changes in 

 pregnancy rates that can be attributed to the 

 effect of herd reduction. Variations by age 

 observed are the result of the locations where 

 the females were obtained rather than of 

 population manipulation. As previously stated, 

 females taken from rookeries or from the 

 rookery fringe areas exhibit pregnancy rates 

 much in excess of those taken from the 

 hauling grounds. While it is known that many 

 rookery females infiltrate the hauling grounds 

 and are included in the kill, it is not possible 

 to identify a mixture that is representative 

 of the herd as a whole. 



Appendix tables 16, 17, and 18 show the 

 reproductive condition, by day and island, of 

 females sampled in 1962. Appendix tables 19 

 and 20 show- the reproductive condition of 

 female seals 4 or more years old and 5 or 

 more years old sampled from the kill. 



TAG RECOVERIES AND TAGGING 

 Tag Recoveries 



A summary of tags and checkmarks re- 

 covered from the kill in 1962 is given in 

 table 13 by sex, age, and island. Tagged male 

 seals were killed only if they were within 

 the length limits prescribed for taking males, 

 or 106.6 to 123.8 centimeters (42 to 48 3/4 

 inches), tip of nose to tip of tail. Only the 

 minimum length restriction of 106.6 centi- 

 meters (42 inches) applied to the taking of
