Appendices to Twenty-sixth Annual Report 



Pollutions— 



1. The existing pollutions are : — Chiefly mill refuse and city sewage. 



2. Remedial measures : — The large sewer referred to in previous reports 



has not yet been completed. One cause of the delay, I believe, has 

 been the unusual height of the river during the whole of 1907. 



The Salmon Disease— 



1. Disease made its appearance this year in the month of December, and 



reached its height in the middle of January. 

 The river was free of diseased fish (comparatively) at end of April. 



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



follows : — 



Males. Females. 

 Kelts, .... 63 37 



The Spawning Season— 



L Fish were first noticed spawning in middle and lower reaches early in 

 November. 



2. The greatest number spawned in December. Principal spawning 



grounds, Alford and Kildrumy districts, 20 to 30 miles up river. 



3. Spawning ceased about end of January. 



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



spawning season is regarded as satisfactory as to numbers and state 

 of river, although the latter was rather on high side. 



Smolts— 



L Smolts were noticed to be migrating seawards early in ApriL 

 2. As a smolt year 1907 was rather below average. 



Artificial Propagation of Salmon— 



L The number of ova secured locally during the past season was 80,000. 



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

 8 fish (3 males and 5 females). Note. — Of the above 80,000, over 

 50,000 appeared to be successfully hatched at hatchery in Fish Street 

 and were put into the river during the first week of June.
