.CJSILSa harengua £allasi. Pacific herring 

 have oeen one o? four leading food species in 

 5 of the 6 years that collections were made 

 off Washington. They were seednd in impor- 

 tance in 1967 (15 6ccurrencea--see fig, 16), 

 and contributed 24,2 percent of the total food 

 volume, 



gflgraulls mordax. Northern anchovies were 

 eaten oy fur" seals collected during 5 of the 

 6. year* off the Washington coast since 1958. 

 fha? ranked fifth in total food volume in 1967, 



and first in 1961 and 1965. Northern anchovies 



were found In the same general locality in 1 961, 

 196S, and 196? (fig. 1?). 



Salmonidae. Salmon occur with greater fre- 

 quency ih the Stomachs of fur Seals taken off 



Washington than in those from other areas. 

 Collectively, the five Pacific salmon have been 

 among the four leading kinds of fish eaten by 

 fur Seals in 5 of the 6 years that collections 

 have been made off Washington. Salmonids 

 ranked fifth in total frequency of occurrence 

 in 1958-67. 



The proportion of food volume contributed 

 by salmon has remained nearly constant since 

 1958, occurring in 138 (1.5 percent) of 9,364 

 stomachs examined from all areas. Off Wash- 

 ington, salmon were found in 61 (6.1 percent) 

 Of 1,001 stomachs examined and in 10.7 percent 

 of stomachs containing food. 



In 1967, salmon ranked first in total food 

 volume (fig. 15) and were found in 18 of 131 

 • tomachi (fig. 17). All five species of Pacific
