-Stcanach contents of fur seals from Bering Sea, 1 July 

 to 5 September 1963 



Trace counts are included in frequency counts. (Trace = an occurrence in which there is no 

 measurable amount of volume, usually only a few vertebra or squid beaks.) 



species, Therobromus callorhinus , called seal 

 fish, from vertebrae found in fur seal stomachs 

 taken in the Bering Sea. They placed it, some- 

 what tentatively, in the family Argentiidae. 

 Chapman (1943) subsequently identified T. 

 callorhinus as a species of Bathylagus . This 

 year was the first since T. callorhinus was 

 described that "seal fish" or a similar fish 

 has been identified from fur seals collected 

 in the Bering Sea. 



Practically all bathylagids found in 1963 

 occurred in stomachs fronn deep water areas 

 of the Bering Sea (appendix fig. 1 ). 



Myctophidae 



Three stomachs from fur seals collected in 

 deep water just north of Unalaska Island 



contained lanternfish (appendix fig. 4). One 

 specimen collected on 1 August was identified 

 as Lampanyctus nannochir . The genus and 

 species of the other two lanternfish collected 

 on 3 and 9 August in the same vicinity could 

 not be determined. 



Gadidae 



Fish belonging to the family Gadidae oc- 

 curred in 58 stomachs examined in 1963, 

 representing 8.8 percent of the total volume 

 of food. Theragra chalcogrammus accounted 

 for 7.7 percent (47 occurrences) of the total 

 food volume, 4.7 percent less than in 1962 

 (Fiscus, Baines, and Wilke, 1964). This fish 

 is considered one of the main food species
