There are 107 Salmon Fishery Districts in Scotland, including the 

 Orkney and Shetland, and the small and relatively numerous areas of 

 the Hebridean Islands. Of these there are 40 provided with Boards 

 for the regulation and protection of salmon fisheries. The salmon 

 fishery rentals of these 40 districts may be stated as fully £145,000. 

 The rentals of the five most important districts are given in the

In Mr. Calderwood's report will be found reference to the various 

 changes which have taken place locally, in netting, introduction of 

 salmon passes, alteration of close times, etc., and also to the inspec- 

 tions made by him in 1912. Eeports from 34 District Fishery 

 Boards have been received by the Inspector, and a digest of their 

 contents will be found appended to Mr. Calderwood's report. 



The work of research into the Life History of the Salmon has been 

 carried on as usual, but only a limited sum, as hitherto, has been 

 available for the purpose. The recaptures in 1912 have been less 

 numerous than in recent years, and on this account further report on 

 this subject is held over. 



PART III. 



SCIENTIFIC INVESTIGATIONS. 



During the year 1912 the scientific investigations in connection 

 with the sea fisheries were carried on under the supervision of 

 Dr. T. Wemyss Fulton, the Scientific Superintendent, as authorised by 

 the Board, on the same general lines as in previous years. Most of 

 the research work has been conducted at the Marine Laboratory at the 

 Bay of Nigg, Aberdeen, and other inquiries in relation to the herring
