except in the fall. However, the fall sample was small 

 (Table 4). On rocky and gravel bottoms, toad crabs 

 were much more abundant (Table 4). Furthermore, the 

 overall mean numbers of snow crab per stomach from 

 cod captured on mud and sand bottoms were substan- 

 tially greater than for cod captured on gravel and rocky 

 bottoms. For toad crab, mean numbers per stomach 

 were higher in cod captured on rocky and gravel bot- 

 tom than from sand and mud bottoms. 



Crab:cod size relationship 



Three distinct size groups of snow crab were detected 

 (Fig. 7). One group, found only during the spring sam- 

 pling, was comprised mainly of recently molted males 

 ranging in size between 77 and 107 mm CW (Fig. 7). 

 These soft-shelled crabs were consumed by cod rang- 

 ing in size between 49 and 66 cm (Fig. 7). The second 

 group of snow crab comprised hard-shelled adult 

 females with eggs. This group of crabs was consumed 

 only by larger cod ranging in size between 67 and 106 

 cm (Fig. 7). The third and most numerous group of
