Appendices to T u: eat y- second Annual Report 



was fully reported on at the instance of the Dumbarton County 

 Council, by the County Analysts, Messrs. R. P. Tatlock and Thomson, 

 and by Dr. M'Vail, Health Officer. From these it appears that the 

 general pollution is less, but that improvements could still be made in 

 particular instances. 



The Salmon Disease — 



1, 2. and 3. None reported suffering from disease. In May, on one occasion, 

 numbers were killed in the Leven by one discharge of noxious matter. 

 Numbers not known. 



The Spawning Season — 



1. Sea-trout were observed spawning in Luss Water during last week of 



September ; salmon in Fruin during last week of October. 



2. Not accurately fixed. 



3. For sea-trout about end of October ; salmon still spawning on 17th 



December. 



4. Rivers are quick rising and quick falling and were in constant fluctuation 



during the spawning season. 



5. Numbers of sea-trout were much above the average, and for salmon few 



recent seasons have seen anything like the numbers. 

 5. Luss Water and Findlas for sea-trout, Fruin for salmon and sea-trout, 

 and the Endrick for the great majority of salmon. 



Kelts- 



1. Not accurately observed. 



2. April and May. 



3. Not accurately observed. 



4. Much above the average, in fact at times abnormally high. 

 Smolts — 



1. Daily from end of April to beginning of June. 



2. Reported so. 



Artificial Propagation of Salmon — 



A completely equipped hatchery, with a constant water supply, has been 

 erected within 10 yards of Luss Water at Luss. Last season, in 6 

 boxe& containing 24 trays, about 77,000 salmon and sea-trout ova were 

 hatched, and in spring the fry were distributed in suitable streams 

 along the west side of the loch. This season few sea-trout ova have 

 been obtained, as apparently the manager missed his market by the fish 

 spawning earlier. About 36,000 brown trout were obtained and 

 many salmon ova (some 100,000) will be got this season. The house- 

 was subscribed for among the members and is being kept up by the 

 Association. 



Proportion of Male to Female Salmon — 

 No accurate observations have been made. 



General Question — 



1. A District Fishery Board ought to be formed (1) for the Clyde and 



Leven, or (2) for the Loch Lomond watershed, including the Leven 

 alone. 



2. The Endrick ought to be under a responsible control. The rights on that 



river are so indeterminate that no individual proprietor will undertake 

 the cost of general watching. Hence the poaching of salmon in it is 

 a scandal. It is the great nursery of the Loch Lomond salmon. 



3. The leap at the Pot of Gartness ought to be made easier for the fish. An 



expert has reported that 2 or 3 dynamite shots would effect the purpose 

 at a cost of £10. There are so few, comparatively, good spawning 

 streams that every extra mile opened up is of the utmost value. 



4. The whole question of Leven pollution should be considered specially 



from the point of view of the fish and not from the point of view of 

 general public health.
