149). Thus the average size of individual barnacles was 

 larger (0.36 g) in Nova Scotia than on the Southern 

 New England Shelf (0.13 g). The biomass of barnacles 

 in the Gulf of Maine and on Georges Bank was less than 

 0.5 g/m 2 . 



Frequency of occurrence was highest (15% of the 

 samples) in the Nova Scotia area and substantial!)' lower 

 (2 to 4%) in the remaining shelf areas. They were 

 absent in the two slope areas (Table 10).
