5. Fish Food Habits . 



Fish stomach contents data are summarized in Figures 19 to 24, 

 which combines data for all sampling sites and dates for each habitat. 

 Staghorn sculpin, threespine stickleback, and juvenile chum salmon 

 captured in submerged level marshes consumed a variety of predominantly- 

 aquatic animals, including amphipods (Corophiim :and Anisogarmarus) , 

 harpacticoid copepods, cumaceans {Hemileuoon) , oligochaetes, and 

 polychaetes (Fig. 19). The diet is diverse partly because data from 

 several samples have been combined. Terrestrial prey were not eaten 

 except by the chum salmon, which ate small amounts of adult insects
