Figure 80 Geographic distnbution of bluefin tag release and recapture data from North Atlantic tagging studies, illustrating 

 offshore- inshore movemenLs and one transatlantic migration 



80) The last fish of this group was 

 tagged at Atlantis Canyon (south of 

 Cape Cod) in November 1960 and 

 recaptured off Cape St. Mary's (near 

 Yarmouth), Nova Scotia, in August 

 1 968. In Its nearly eight years of free- 

 dom, its weight had increased from 

 69 kg (estimated) to 185 kg, bringing 

 it into the "giant" category This re- 

 turn was the first to show a migration 

 from New England to Canadian wa- 

 ters. 



Movements dunng the summer 

 feeding season in coastal waters, as 

 indicated by the seasonal progres- 

 sion of the returns from offshore re- 

 leases and also by the movement of 

 the fisheries, is from southwest to 

 northeast This general pattern could 

 be observed from off Maryland to 

 the southern part of the coast of 

 Maine. Medium fish have also been 

 abundant in Nova Scotian waters in 

 some years, off Wedgeport (near 

 Yarmouth) and, more regularly, in 



St. Margaret's Bay (near Halifax) The 

 years of abundance at Wedgeport 

 generally coincided with those in 

 Cape Cod Bay, as did the ages of the 

 fish taken The medium fish were 

 often abundant in Cape Cod Bay 

 through most of August, but did not 

 usually occur in numbers off 

 Wedgeport until September These 

 facts suggest a continuation of the 

 northeastward movement from Cape 

 Cod to Nova Scotia. However, fish 

 were usually numerous in Cape Cod
