AbstractThe populations of the bivalve Callista chione (L.), have experimented a severe decline in recent years in the Maresme coast, Catalonia, (Spain), where it has a considerable commercial interest. This trend is framed within a general decline of most other fisheries and tends to be attributed to overfishing. We have addressed other possible causes such as changes in the quality of coastal waters in terms of chemical nutrient or chlorophyll concentrations or the effect of sand extraction for beach nourishment, but have failed to establish general relationships with catch per unit effort
