Consideration of the results of the exploratory 

 fishing and tagging studies in the inshore and offshore 

 areas in their entirety yields a reasonable picture of 

 the distribution and migratory routes of the major 

 stocks of adult sockeye salmon bound for Bristol Bay. 

 The exploratory fishing in the eastern Bering Sea east 

 of long. 170°W (Fig. 2) showed that the main migra- 



158° 



tion route of sockeye salmon returning to Bristol Bay 

 is in the offshore waters of the southern half of Bristol 

 Bay (Fig. 11). Exploratory fishing and the offshore 

 and inshore tagging studies showed that Bristol Bay 

 stocks remain in the offshore waters until they are 

 within 32 to 80 km of the mouths of their home-river 

 systems.
