anglers, and the remainder elsewhere in the Maritime Provinces in commercial salt- 

 water nets. However, more were taken in the freshwater section of other rivers than 

 in that of the Miramichi (C. J. Kerswill, personal communication). 



A considerable number of marked fish originating in the Port Daniel River, 

 Quebec, has also been taken around Newfoundland (.^), as have specimens marked in 

 Maine rivers (^5). 



In contrast to the wide distribution of Atlantic Salmon from these rivers, only 

 one out of 31,359 Margaree River smolts was recaptured on the east coast of New- 

 foundland; they were taken mostly in the waters of western Cape Breton and the 

 neighboring mainland of Nova Scotia {66: 381). 



Specific examples of results from taggings at sea are as follows: 



Off Bonavista on the coast of eastern Newfoundland {21) : 



Of 386 grilse tagged, 140 were recovered — 93 "/o in Newfoundland waters, 7 "/o 



in Canadian mainland waters. 



Of 68 older specimens tagged, 28 were recovered — about 57°/o in Newfoundland 



waters, 40 "/o in Canadian mainland waters, and somewhat less than 4 "/o off 



Labrador. 

 In Cabot Strait between Newfoundland and Nova Scotia (J^): 



Recaptured along the eastern part of the north shore in the Gulf of St. Lawrence 



and in waters off the northern part of western Newfoundland. 

 In the eastern end of Belle Isle Strait {14): 



Recaptured in parts of the Gulf of St. Lawrence where fish tagged in Cabot Strait 



did not go. 

 The results of the Cabot Strait and Belle Isle taggings were interpreted by Belding 



{14) as indicating two distinct stocks. 



Since Atlantic Salmon do not originate in Massachusetts rivers, specimens taken 

 from time to time off that coast probably come from the rivers of eastern Maine or 

 even from the St. John River. Other examples of rather extended movements are af- 

 forded by the capture of Salmon by trawlers 90—100 miles seaward from the outer coast 

 of Nova Scotia, and 100 miles from the nearest land, on Georges Bank {l8~). 



European findings also support the conclusion that some of them make extended 

 journeys (up to 1,600 miles), while others appear to move relatively short distances 

 {102). Especially definite are Aim's observations (2). Young fish from rivers tributary 

 to the Baltic and Gulf of Bothnia migrate to the southern part of the Baltic, where they 

 feed and then return to their rivers as grilse or older fish. Smolts from the rivers of 

 western Finland and from the northern and middle parts of Sweden move down the 

 Swedish coast to the southwestern corner of the Baltic or travel across the mouth of 

 the Gulf of Bothnia and then down to the Polish and Pomeranian coasts. Fish from 

 Estonia and Latvia find an adequate quantity of food comparatively close to their 

 native rivers. 



Apart from the capture of one Scottish fish in Greenland waters, there is no
