Comparison of daily estimated ration with amount of food in stomachs for 5 pilot whales and 4 common dolphins taken incidentally 

 during March-April 1989, off the northeastern United States. AM = Atlantic mackerel, LS = long-finned squid. 



'Obtained from a length-weight relationship from Lockyer (1991) for pilot whales, and from J. Mead (Smithson. Inst., pers. commun. 



1989) for common dolphins. 

 "From a relationship between resting metabolism and body weight (Lockyer 1981) and a correction for assimilation and activity (Kenny 



et al. 1983). 

 3 Obtained by converting prey weight to Kcal by using 1.43 Kcal/g for Atlantic mackerel and 1.34 Kcal/g for long-finned squid (Steimle 



and Terranova 1985).
