Appendices to Twenty-sixth Annual Report 



Obstructions to the Passage of Fish— 



t. D im dykes disused, built, or iu prospect : — No change since last report. 



2. With regard to the observance of bye-laws : — No change since last report. 



3. Fish passes built or in prospect : — No change since last report. 



4. Natural obstructions not yet dealt with are : — Falls of Tunimell and Falls 



of Keith. 



Pollutions— 



1. The existing pollutions are : — Sewage of Perth and villages in district, 



bleaching works, &c, and several distilleries. 



2. Remedial measures : — Filter works at Blairgowrie and settling ponds 



at Aberfeldy Distillery. The whole subject of pollution in the district 

 is still engaging the attention of the Board. A full report on 

 the subject, compiled by the Chairman of the Board, was recently 

 submitted to the Board, and copies of that report have been laid 

 before the Secretary for Scotland, the Board of Agriculture and 

 Fisheries, LondoD, the Fishery Board for Scotland, the County 

 Council of Perth, and the Town Council of Perth, with the view of 

 some definite action being taken to remedy what is acknowledged to 

 be a serious injury to fishings. 



The Salmon Disease— 



1. Disease was prevalent every month of the year, and reached its height 



in December and January. 

 The river was never free from disease, and has not been for two years 

 at least, and it is doubtful if it has been wholly free for the last ten. 



2. The number of diseased fish taken from the river and destroyed was as 



follows : —

The Spawning Season— 



1. Fish were first noticed spawning on 31st October in the Garry at Blair 



Athol, but they had been spawning some time before they were 

 observed, as they were nearly spawned out, and some spawned fish were 

 seen at same time. 



2. The greatest number spawned about the last half of November and first 



half of December. 



3. Spawning ceased about the middle of January. None actually seen 



after 10th of January. 



4. As regards numbers of breeding fish, and state of the water, the past 



spawning season is regarded as a fairly average one. The river 

 during most of the time was slightly heavy, perhaps, for the very best 

 results, but otherwise conditions favourable. 



Smolts— 



1. Smolts were noticed to be migrating seawards in March. 



2. As a smolt year 1907 was considered rather poor. There was no fishing 



in estuary for them this year, but by observation as far as could be 

 seen the crop was a small one. 



Artificial Propagation of Salmon— 



1. The number of ova secured locally during the past season was 45G,000, 



which is the full carrying capacity of the Board's hatchery at 

 Dupplin. 



2. In securing ova the numbers of male and female fish captured were 



respectively 68 male and 87 female. The total number of fish netted 

 was 290.
