We consider it unfortunate that no return of rod-caught fish is 

 available. Although the total may be insignificant as compared with 

 the coast netting return, it would be extremely valuable as showing the 

 beneficial results to the rod from the removal of river nets, and there- 

 fore the increase in the potential stock of breeding fish. We have con- 

 sistently advocated the policy of developing as far as possible the coast 

 salmon fishing, and of confining the use of sweep nets in rivers and 

 estuaries so as to allow a proportion of every run of fish to ascend to 

 the fresh waters, their natural and only spawning grounds. 



It appears that in the case of several rivers where sweep netting 

 has been reduced, a satisfactory increase lq the number of fish has 

 resulted. The Inspector ia his report, herewith, states that there 

 are comparatively few rivers in Scotland in which, nowadays, netting 

 is carried on to excess, but he points out that, from the decline in the 

 general market supply, it would appear that the breeding stock is 

 insufficient to maintain a satisfactory catch. 



From the results of the Salmon Kesearch, interrupted by the war 

 but now happily recommencing, it has become sufficiently clear that 

 in spite of the well-ascertained homiag instinct of the salmon, the 

 nets on one part of the coast may be operating amongst fish from a 

 different district. One of the main objects in the iavestigations 

 now beirig resumed is to ascertain if possible how far movements of 

 fish along the coast are likely to affect the stock of given districts. 

 In 1915, for instance, when the experimental nets were fishing at 

 Kintradwell, on the east coast of Sutherland, a large number of the 

 marked fish were recaptured on the east coast of Caithness, while some 

 had penetrated to the Pentland Firth. It is proposed to follow up 

 as far as possible this northward movement of fish, and by marking 

 them at a point further north and again releasing them, to ascertain 

 their further movements.
