Figure 31. — Number of seals seen per hour of effort. In each square (areal unit) occupied by a research vessel In 

 February 1966, off California. The sides of each square measure 18.52 km. (10 nautical miles). Squares V24-H25 and 

 V23-H22 were not occupied. See table C-2. 



the proportion of young animals in the popula- 

 tion. Males formed only a small part of the 

 population in this area and usually arrived later

TAG RECOVERIES 



One tagged male and 26 taggedfemales were 

 taken in 1966 (table 49). Tagged seals of both 

 sexes made up 8.5 percent of those age 4 and 

 younger and 5.3 percent of those age 5 and older. 



No seals tagged on Robben Island or on the 

 Commander Islands were taken at sea by U.S. 



research vessels; however, three seals tagged 

 as pups on Southeastern Rookery, Medny Island 

 (Commander Islands) in 1965^^ were found dead 

 on U.S. west coast beaches in 1966 by beach- 

 combers. One was found 20 March on a beach 

 near Tillamook, Oreg. (lat.45°33' N.), another 

 on 17 February near Moclips, Wash. (lat.
