LANGTON: DIKT OVERLAP BETWEEN SEVENTEEN NORTHWEST ATLANTIC EINFISH 



This observation may not only be reassuring to 

 the taxonomist but is also of significance to fish- 

 ery biologists in their attempts to identify eco- 

 logical units. It suggests that future food habit 

 studies should be directed towards the juvenile, 

 or at least smaller, stages of closely related spe- 

 cies if the goal is to understand how finfish co- 

 exist by partitioning food resources in the marine 

 environment. 



ACKNOWLEDGMENTS 



My sincerest thanks go to the people who helped 

 generate the diet overlap data described in this 

 paper: Bill Freund, Woods Hole Oceanographic 

 Institution, wrote the computer program that 

 automated the diet overlap calculations; Jacki 

 Murray and John Hauser, Northeast Fisheries 

 Center, modified the program and generated 

 most of the data; Jean Garside and Margaret 

 Hunter, Department of Marine Resources, devel- 

 oped the three dimensional plotting program 

 and generated the figures for the paper.
