ing migration, and changes in the ecology of the ocean 

 habitat of salmon, Penobscot and Connecticut smolts 

 are probably exposed to different predator and prey 

 communities during the course of their migrations. 

 These differences would be expected to manifest 

 themselves in growth differences, and as a conse- 

 quence, in differences in survival and maturation of 

 the two stocks.
