remained at beach sites over winter and were joined 

 by Atlantic silversides and mummichog to form a 

 winter assemblage (Table 4). 



During summer an "offshore, hard-bottom" 

 assemblage consisting of adult gadids (Atlantic cod, 

 haddock, white and red hake), adult flounders (win- 

 ter yellowtail), ocean pout, adult sculpins, and skates 

 assembled inside Passamaquoddy Bay. Sea raven, 

 longhorn sculpin, ocean pout, and little skate 

 remained at this site over winter and were joined by 

 juvenile fishes from the beach zone. The other 



species apparently move to offshore sites in the Bay 

 of Fundy and/or to the Scotian Shelf (McCracken 

 1959; Wise 1962; Edwards 1965; Kulka and Stobo 

 1981). 



The "offshore, soft-bottom" assemblage consisted 

 of American plaice, witch flounder, white hake, four- 

 beard rockling, and skates as described by Bigelow 

 and Schroeder (1939). This group at station B was 

 the most stable assemblage studied and had the 

 largest regular component. Conversely, similar 

 assemblages which occurred at the shallower, soft-
