This report summarizes the findings of the project, focusing on the Torridge Catchment, initiated to investigate the circumstantial evidence linking changes in agricultural land use to deterioration in both river water quality and salmonid populations. The Torridge catchment was chosen for the study because of a decrease in salmonid rod catches, along with a general deterioration in river quality.
Historical changes in the River Torridge; comparison between study catchments; conclusions on the factors affecting river quality and fishery status; recommendations for future management.
