The Salmon Disease — 



1. A good deal of disease, first seen in end of October, worst in November, 



still observable in a modified degree. 



2. Normal. 



3. Three hundred fish taken from the river in November, proportion about 



2 females to 1 male. In December 150 fish taken from river — propor- 

 tion of sex same. No clean fish. 

 Note. — It has been slightly worse this year than in some previous years. It is believed 

 that the polluted waters from the mills, and obstruction to the ascent of fish 

 by dykes, promote disease, the dykes having the effect of causing the fish to 

 congregate in hundreds in limited spaces. The disease has always been worst 

 on the lower river, where there are paper mills.

60,000 ova put into the hatchery at Fish Street towards end of December.

 hatchery is carried on at the mutual expense of the Dee and Don 

 District Boards. 



Proportion of Male to Female Salmon — 

 No information obtainable on these points.
