Mr. Calderwood, in his report, Appendix N, refers to several 

 districts in which, owing to the removal of river netting and netting 

 close to the mouths of rivers, a marked improvement has resulted in 

 the stock of salmon. He points out that the improvement cannot be 

 shown in the weight of salmon carried by railways, etc., since rod- 

 caught fish is not marketed to any extent. He refers specially to the 

 Deveron, Spey, and Ayr as rivers in which this improvement has 

 lately been shown. He has similarly referred in previous years to 

 the Helmsdale and the Thurso. 



During 1910 he inspected the various districts of the Solway with 

 reference more especially to the practice of using fixed nets on the 

 tidal flats, for the capture of white-fish, as well as for the capture of 

 salmon. This question has formed the subject of more than one 

 inquiry in the past, and is to receive further attention in the near 

 future. He also visited the districts of the Leven and Loch Lomond, 

 Add, Awe, the Isle of Mull, Spey, Deveron, and Don. Eeference is 

 made to various matters of interest connected with these districts in 

 the Inspector's Keport. 



The rentals of 31 districts from which reports have been received 

 amount to the sum of £121,373. In 1909 and 1908 the rentals of 33 

 districts w^ere respectively £140,223 and £121,521. The following are 

 the rentals of the five most important districts since the year 1900: —

In addition to Appendix 0, containing reports from District 

 Fishery Boards, will be found a statement of the number of boxes of 

 salmon delivered at or near Billingsgate in each month of the year 

 1910, and the average monthly price, including returns as to Scottish, 

 English, Irish, and Continental salmon. Other Appendices are: — The 

 rateable values of salmon fisheries in the various districts in Scotland ; 

 the list of close times applicable to the various districts ; and a list 

 of the Chairmen and Clerks of District Fishery Boards. 



Published as separate papers are two by Mr. Calderwood on the 

 results of salmon marking, being a seventh paper by him on this sub- 

 ject, and on the infrequency of spawning in the salmon, as shown by 

 the examination of scales. By Prof. Noel Paton a paper is also 

 published along with those, on a study of three fish received as 

 " mended male kelts."
