The following report presents the results of the validation study performed on Restormel fish counter (SX 107 613) in 1997. The aim of this work was to assess the counters ability to accurately count migrating adult salmon (Salmo salar, L) and sea trout (Salmo trutta, L) and establish a means by which to distinguish between the two species. The validation of Restormel fish counter is necessary for three principle reasons: To obtain an estimate of the counters current and historical operating efficiency that will enable accurate interpretation of counter data collected over the last four years; To enable modifications, if necessary, to the current operational set-up of the counter to improve the level of counting efficiency; To provide an independent, accurate assessment of the salmon and sea trout runs on the River Fowey to support fishery management decisions.
