APPENDIX B 



Overall Prey of 60 Predators Which Were Fully Sampled 



and Well Represented in Collections 



during the NEFSC's 1977-80 Bottom Trawl Surveys 



Stomach content data for 60 predator species sampled 

 during the 1977-80 NEFSC bottom trawl surveys are 

 presented in Tables B-l though B-60. These tables 

 represent predator species for which 25 or more individuals 

 each were sampled. 



For 44 of these 60 species, stomach content data are 

 given according both to predator length categories and to 

 geographic areas of collection. Those 44 species were 

 selected based on the greatest number of individuals (at 

 least 25) and areas (at least two) represented by the 

 samples. For the remaining 16 of these 60 species, 

 stomach content data are given according only to predator 

 length categories. 



The tables for the 44 predators listed by both predator 

 length and geographic area have two subtable numbers 



(e.g., Tables B-l a and B-lb, respectively). The tables for 

 the 16 predators listed by only predator length have one 

 main table number (e.g., Table B-3). 



Stomach content data have been summarized, when 

 necessary, to fit on one page to aid in making comparisons 

 among predator species. Whenever the list of prey species 

 had to be so summarized, fish prey, in almost every 

 instance, were left intact at the expense of those other prey 

 which had contributed the least percentage by weight to the 

 predator's diet, and which were then condensed into higher 

 taxonomic groups. In instances when the list offish prey 

 had to be summarized, only species which made up <1% of 

 the total stomach contents by weight and which were not 

 commercially important were then lumped into higher 

 taxonomic groups.
