Abstract:
It has long been known that many adult salmon (Salmo salar, L) are picked up dead in the estuary of the River Parrett, and has sometimes been assumed that they were suffocated by high concentrations of suspended solids (SS) in the water, as recorded for example, in evidence given to the Salmon Commissioners in 1902. At the same time, however, concentrations of dissolved oxygen (DO) are known to have been low and their over-riding lethal effect is suspected. Data on water quality and catches of dead and live salmon have, therefore, been examined to investigate the role of these two factors in the mortality.
