Table 4 



Stomach contents of adult bluefish captured during the 1994 and 1995 National Marine Fisheries Service autumn bottom trawl 

 survey. %F=proportion of bluefish stomachs containing a prey (±SE). %W=proportional contribution of identifiable prey to blue- 

 fish diet by weight (±SE). Note that proportions from cluster estimators do not add up to 100*^. SE=standard error from variance 

 estimators for cluster samples.
