A total of 302 seals selected and tagged as 

 yearlings on St. Paul Island in 1961 (M-series), 

 1962 (N-series), and 1963 (O-series) were re- 

 covered on the Pribilof Islands in 1964. The 

 recovery information is given in tables 11 

 and 12. 



Information on 45 Soviet-tagged seals killed 

 on the Pribilof Islands in 1964 is given in 

 table 13 and in appendix table 15. 



Tagging--Pups .-- The number of pups tagged 

 in 1963 is listed in table 14 by rookery, and a 

 record of pups tagged on the Pribilof Islands 

 since 1941 is given in appendix table 16. Tag 

 and checkmark locations on pups tagged since 

 1947 are shown in appendix figure 1. 



Of 24,991 Q-series tags attached to pups in 

 1964, 19,998 were used on St. Paul Island and 

 4,993 on St. George Island. This was the second 

 year of a 2-year program designed to deter- 

 mine the influence, if any, of age of pups when 



tagged on survival. As in 1963, half of the pups 

 on St. Paul Island were tagged in late August 

 and half in late September. Mortality rates of 

 the two groups will be compared in 1967 when 

 the survivors return at age 3. 



All tags used in 1963 and in August 1964 

 were attached at the hairline of the front 

 flipper. Tags used in late September 1964 

 were attached about 2 inches toward the tip 

 of the flipper from the hairline. At this point, 

 tags will not interfere with muscles and blood 

 vessels as they do when attached at the hairline. 



Under the reduced tagging program, a crew 

 of 10-12 men is adequate in that this number 

 is large enough to complete tagging on the 

 largest rookeries in 1 day, yet small enough 

 to permit quality in tagging and gentler handling 

 of pups .
