SUMMARY 



LITERATURE CITED 



1 . A quantitative analysis of the stomach 

 contents of 1, 287 haddock from Georges Bank, 

 captured by means of otter trawls, form the 

 basis of this study. 



2 . The average body length of all haddock 

 examined was 44 centimeters . Minimum and 

 maximum lengths were 14 and 75 centimeters, 

 respectively. Calculated body wei^ts aver- 

 aged 2 . 1 pounds, with extremes from 0. 1 to 



9 . 2 pounds . 



3 . Stomach content volume varied from 



to 110.0 cubic centimeters; average volume 

 was 2.2 cubic centimeters.

 the primary food groups in decreasing oidei 

 of importance were: crustaceans, mollusks, 

 echinoderms, annelids, and fish.

5, Distinct differences in food of haddock 

 from several parts of Georges Bank warranted 

 the establishment of three food type areas . 

 These areas and the predominant food of had- 

 dock in each are as follows: Georges Basin - 

 brittle -stars. Northeast Peak - decapod 

 crustaceans, and Southeast Part - amphipods . 



6, Most of the food organisms were small, 

 sedentary or slow-moving benthic animals, 



7 , Differences in the food habits between 

 large and small haddock were of a minor 

 nature . 



8 . During the spawning season, February 

 May, the haddock contained smaller quantities 

 of food than fish taken at other seasons of the 

 year. 



9. Seasonal trends in diet composition 

 were not apparent. 



10. In this study more than 173 species of 

 food organisms were observed m the haddock's 

 diet; only 11 species were present m large 

 quantities .
