OCCURRENCE OF FOOD ITEMS 



Food items found in the stomachs 

 of king and coho salmon ranged from 

 freshly ingested organisms to uniden- 

 tifiable jellylike masses. Classification 

 of many of the items was limited by 

 the degree of disintegration. In some 

 instances identification of organisms 

 was facilitated by otolith and vertebral 

 comparisons. Items found and their 

 relative volumes are listed in 

 table 2. 



By Season 



Certain differences in the fre- 

 quency of occurrence of food items 

 existed between the 2 years (table 3).
