Information on marine and freshwater survival and exploitation of River Bush salmon was developed into a model illustrating the potential ranges of grilse production per 1000 smolts. Values were attributed to the grilse ‘crop’ at each of three potential production stages – commercial landings, angler catches and fertilized egg production – using both published and derived valuations. Using the model, a range of values per wild smolt was calculated for grilse production on the River Bush.
