THE MIGRATION AND CONSERVATION OF SALMON 



also has a few fish that travelled up to 45 

 miles per day and one remarkable specimen 

 which, on the data given, moved at no less 

 than 60 miles per day, over a distance of 

 nearly 700 miles. 



In Scotland other marking experiments 

 have been carried out in earlier years which 

 demonstrated among the fish concerned a 

 more local movement than has been shown in 

 the work which I have just mentioned. The 

 results of these earlier experiments were 



confirmed by the Norwegian fish which were 

 recaptured close to the place of marking and 

 by another station which was established at 

 the mouth of the Trondheim Fjord in that 

 country. 



The first sea marking experiments were 

 carried out in 1913 and 1914 in the inner 

 part of the Moray Firth where the distribu- 

 tion of recaptured fish was entirely different 

 from that already described for the north- 

 west coasts and Norway.
