Appendices to Twenty-second Annual Report 



Pollutions — 



1, No. 



2. The large sewer referred to in the previous reports has not yet been com- 



pleted, but it will probably be so before another year. When it has 

 been finished it should do much to purify the lower river. 



The Salmon Disease— 



1. A good deal of disease showed itself about the middle of November 1903, 



mainly in the upper reaches, but the river became flooded about 1st 

 December, since which date it has disappeared. 



2. Low when it began. 



3. 257 salmon taken from the river about the end of November and 



destroyed — mostly male fish, but no exact record kept of sex or 

 otherwise. 



The Spawning Season — 



1. Middle of October in upper reaches — later in lower water, but this 



supposed to be owing to the river becoming flooded. 



2. From end of October to middle of November. 



3. Practically about end of March. 



4. Low on the whole. 



5. More — being later. 



6. The Clunie, Geldie, Gairn, Muick, and Feugh, all tributaries of the 



Dee. Also some good spawning beds in upper reaches of main river. 

 Of the tributaries — the three first mentioned in this answer are 

 best. 



Kelts— 



1. Middle of December. 



2. During April. 



3. Never quite free. 



4. Bather in flood in April when chief migration going on.

 October 1902. Commenced hatching early in February. During 

 hatching period about 18,000 dead ova removed from the boxes — the 

 remainder successfully hatched and put into the river, apparently in 

 a healthy condition, about end of May. The hatchery belongs to the 

 Dee District Board.

 actual enumeration.
