COSY - Density-dependence in cockle populations: possibilities for a sustainable fishery

Objectif

This project will contribute to our understanding of the role density-depending processes in the dynamic of an exploited bivalve species ( Cerastpderma edle ) from natural beds in the Wadden Sea and the Oosterschelde estuary.

By using an innovative modelling approach the B-N diagram, some specific issues will be addressed to identify the relevant spatial scale(s) at which density dependence occur and may affect population dynamics of C. edule: possible occurrence of density-dependant mortality in cockle populations: the factors responsible for density-dependant growth and or survival in cockles i.e competition for space or trophic resources: and finally possible impacts in terms of Economy i.e. sustainability and profitability of the cockles fisheries and of ecology, i.e. protection of estuarine habitants including food reservation for wading birds.
