1 Data for 1958 taken from Ford Wilke, Karl Niggol, and Clifford H. Fiscus. 1958. Pelagic 

 fur seal investigations, California, Oregon, Washington, and Alaska, 1958. Bureau of Commercial 

 Fisheries, Marine Mammal Biological Laboratory, Seattle, Wash. [Processed, 96 pp. J 



Data for 1959 from Karl Niggol, Clifford H. Fiscus, Jr., and Ford Wilke. 1959. Pelagic 

 fur seal investigations, California, Oregon, and Washington, 1959. Bureau of Commercial Fisheries, 

 Marine Mammal Biological Laboratory, Seattle, Wash. [Processed, 92 pp. J 



Data for 1961 from Clifford H. Fiscus, Karl Niggol, and Ford Wilke. 1961. Pelagic fur 

 seal investigations, California to British Columbia, 1961. Bureau of Commercial Fisheries, Marine 

 Mammal Biological Laboratory, Seattle, Wash. [Processed, 87 pp. ] 



Data for 1964 from Fiscus and Kajimura (1965); data for 1965 from Fiscus and Kajimura (1967). 



2 All males are age 5 or younger, except one 8-year-old. 



since 1958 are shown in table 27. Generally, 

 the age and sex composition of the population 

 off Washington is similar to that of the popu- 

 lation off California (U.S. Fish and Wildlife 

 Service, Bureau of Commercial Fisheries, 

 1969). The proportion of females ages 1 to 



4 years increases as summer approaches. 

 This increase may be explained in part by the 

 northward migration of gravid females and 

 probably by a gradual increase in the number 

 of young animals that are still appearing from 

 seaward and moving south.
