The cod, one of the most widely fished species in the North 

 Atlantic, lives on offshore banks and along our coasts from 

 Maine to Virginia. 



made of bottom-dwelling organisms on the Continental 

 Shelf from Nova Scotia to New York. These organisms, 

 many of which are the food of groundfish, are very 

 important parts of the ecological web of life in the sea. 



A 3-year series of bottom surveys provided a base of 

 knowledge of the seasonal changes in groundfish com- 

 munities in the area. Growth rates of many species have 

 been determined, the young stages identified, and the 

 environmental conditions in relation to survival at various 

 stages in the life cycle have been assessed. 



Visiting investigators can be provided laboratory space 

 with running sea water and space on the Albatross IV. 

 Arrangements for space should be made with the Lab- 

 oratory Director well in advance of the reservation dates 

 desired. 





Although the sea scallop spends most of its time resting on the 

 bottom, it escapes starfish and other enemies by "jet-propelled" 

 darting movements.
