"To Hit et al.: Sizes of walleye pollock consumed by Eumetopias jubatus 



531 



Steller sea lions can consume a wide range of different 

 size pollock (4-78 cm). Whether or not these differences 

 in sizes of pollock consumed between regions and de- 

 cades reflect differences in availability, size preferences, 

 or year-class strength is not known and requires further 

 study primarily with fine-scale data from scientific sur- 

 veys and concurrent scat collections.
