In 1983, 35 potters and 14 dories from Granville harbour and the Blainville maritime station landed 3,900 tonnes of whelk (for a value of 7.5 million francs).

This study aimed to provide decision-making elements for rational management of the resource : stock abundance, catches per unit effort, mortality due to fishing effort and biological properties.   In order to assess the impact of measures to organise the fishing effort on total catches in balance, two predictive models were used: Pella and Tomlinson's generalised production model and Ricker's...
