Fourteen samples of gooseneck barnacles 

 were collected during the spring. Lepas 

 pectinata pacifica, including some cyprid 

 stages, were found in all samples, and two of 

 the samples included Lepas anatifera . Most 

 of the barnacles were small; the capitulum of 

 the largest was only 8 mm. long. Gooseneck 

 barnacles were also found on four seals 

 collected in Bering Sea in July and August. 

 L. £. pacifica was present in all four samples 

 and L. anatifera in one. 



Food 



The food and feeding habits of fur seals off 

 the Pacific coast of the United States were 

 summarized by Fiscus, Baines, and Wilke 

 (1964). Observations at sea and examinations 

 of stomachs show that fur seals feed primarily 

 at night and during early morning, although 

 they feed actively throughout the day in areas 

 where the food species remains in upper water 

 layers in daylight. Usually stomach volumes 

 were greatest early in the morning and de- 

 creased until late afternoon. 



Stonnachs from 876 fur seals from four 

 areas were examined. Seventy-two percent of 

 the stomachs contained at least trace * announts 

 of food. The percentages of stonnachs con- 

 taining food from the four areas were: Cali- 

 fornia, 75; Oregon, 100; Washington, 79; and 

 Bering Sea, 69. The samples off Oregon (10 

 stomachs) and Washington (28 stomachs) are 

 too small for meaningful comparison with 

 other data. The proportion of fish and squid 

 in fur seal stomachs varies from year to year 

 depending on the locality where seals are 

 feeding. Collections made off the Continental 

 Shelf usually contain nnore squid; those made 

 on the Continental Shelf and slope usually con- 

 tain more fish. The percent of fish and squid 

 in 1964 were: 



Fish Squid

California 84.6 15.4 



Oregon 100.0 Trace 



Washington 93.8 6.2 



Bering Sea 64.4 35.6 



Food specimens found in fur seal stomachs 

 were identified by (1) comparing them with 

 preserved whole fish and skeletons and (2) 

 using identification keys by Andriashev (1937; 

 1954), Berry (1912), Clemens and Wilby (1961), 

 Clothier (1950), Evermann and Goldsborough 

 (1907), Sasaki (1929), Schultz (1936), and 



Wilimovsky (1958). 7 To provide information 

 on the size of the food species in fur seal 

 stomachs, various counts, measurements, and 

 weights of the rennains of undigested speci- 

 mens were taken whenever possible. 



The following fishes and squids were identi- 

 fied from stomachs of fur seals collected in 

 1964. The common and scientific names of 

 fish are from the published list (where appli- 

 cable) of the American Fisheries Society 

 (1960).

The detailed results of examinations of 

 stomach contents are shown in tables 5-8. The 

 locations where each food species occurred in 

 stomachs are shown in appendix figures 1-8. 

 Major food items usually remain the same each 

 year in a given area, but individual rank nnay 

 change. Figure 4 shows the percentage of 

 stomach content by volume and percentage 

 occurrence of food species that contributed 

 more than 2 percent of the total volume.
