Abstract:
A study has been made of the River Don, Aberdeenshire, as to the relationship between the catches of migratory fish on rod and line and the quality of the water, particularly as to the concentrations of dissolved oxygen (DO) since, during some past seasons, when catches have been below average, concentrations of DO at Grandhome have at times also been low. A preliminary examination of annual combined catches of 'salmon' and grilse (salmon that have spent only one winter at sea before returning to the river), expressed as corresponding proportions of those in the R. Dee, Aberdeenshire, had indicated a slight correlation with annual average DO and a much more significant correlation with river flow. However, no firm conclusions could be drawn from that analysis without having access to information on catches in the R. Dee, inter alia.
