The purpose of this study was to verify whether any changes in sex ratio might occur in soft-shell clams ( Mya arenaria) located in an intertidal harbor zone located at the mouth of the Saguenay Fjord in the Saint Lawrence estuary (Baie Sainte-Catherine (BSC), Québec, Canada) likely to be contaminat...
