Vitellogenin content in European eel ( Anguilla anguilla ) in Flanders, Belgium
As part of a large-scale monitoring program of bioaccumulating contaminants in the European eel ( Anguilla anguilla ) in Flanders (Belgium), we investigated potential effects of xenoestrogens in these fish. The present paper describes the results of the plasma vitellogenin (VTG) content, measured in...
