An assessment of the potential for the application of two simple models to Atlantic salmon, Salmo salar, stock management in chalk rivers
Many salmon populations in the UK are under threat, which is assumed to result from a combination of anthropogenic and natural factors. Positive management is required to bring them back to their former productivity levels. An attempt has been made to use two simple models to assess the suitability...
