60 Thirty-ninth Annual Report of the Fishery Board for Scotland. 



for other reasons which have been set forth in previous Eeports. 

 There has been no revision of these Acts since 1868. 



The Board's investigations into the migratory movements and 

 habits of salmon were continued during 1920 and have yielded 

 interesting and valuable results, which are being published in a 

 separate paper. 



In view of the probability of further schemes being promoted for 

 the utilisation of water-power from Scottish rivers, and of the danger 

 to spawning grounds thereiu involved, the question of the value 

 of artificial propagation of salmon assumes increased importance, 

 and during the year the Board put forward proposals for the conduct 

 of hatching experiments to be carried out in the River Add, but 

 owing to the necessity for national economy the experiments have 

 had to be postponed. 



With a view to co-ordination and economy proposals were also 

 made for the centralisation under the # Board's charge of the work 

 of examining the salmon scales collected throughout the United 

 Kingdom and formerly dealt with separately by the Fishery de- 

 partments of England, Scotland and Ireland. 



The results of the researches made on the sea trout of the Eiver 

 Forth by Mr. W. J. M. Menzies, assistant to the Inspector of Salmon 

 Fisheries, were issued during the year in the Board's Salmon 

 Fisheries series of scientific publications.
